Mortuus is a round-based zombies FPS for 1–4 players (solo or online co-op) from developer Hamuno. Each run builds a new procedurally generated brutalist map, in day or night, clear weather or storm. You buy doors, find the power switch, take guns off the wall or from the Mystery Box, buy perks, upgrade guns at the Gun Ascension altar and draft one upgrade after every round. Steam lists over 30 guns, five elements, special enemies and boss fights, plus a hidden ritual that wakes the Mother. Full release: January 11, 2027 on Steam for Windows, macOS and Linux; a free demo is out now. Field note ## Read the lights, not the map The map changes every run, but the lamps don’t. Players in the official Steam discussions point to two constants: [ Red lamp Door to Power — the generator room.

In co-op, each player has their own.

Players mention a Second Chance perk and a melee perk. [Official] [Official] [Players] - **[Gun Ascension](https://mortuusgame.com/wiki/perks-and-upgrades/#gun-ascension)**: Feed your gun to the altar and choose how it gets stronger, as many times as you can afford.

Mortuus is still in development; values can change between demo patches and the full release. See [how we source](https://mortuusgame.com/about/). --- # Enemies & bosses URL: https://mortuusgame.com/wiki/enemies/ Last verified: 2026-10-29 Roster Regular zombies chase, cut you off or go around you from early rounds. Later, specials join: the Juggernaut, the Lope, which runs on its arms, and the Skitter, which comes across the ceiling — “and more.” There are boss fights, and a hidden ritual wakes the Mother. [Official] ## Roster Common ### Zombies The horde. From the early rounds, some chase you, some cut you off and some go around. They get tougher as rounds climb. [Official] [Press] Tip Shoot the legs and they crawl — a cheap way to slow a pack. State ### Crawlers Not a separate type: zombies whose legs you shot off keep coming on their arms. [Official] Tip Watch the floor in tight corridors. Special ### Juggernaut Named on Steam among the later-round specials. The store text describes a special that charges through its own horde to grab you. [Official] Tip Keep an escape lane when you hear the horde parting. Special ### Lope Runs on its arms. [Official] Tip Fast and low — aim lower than head height. Special ### Skitter Comes across the ceiling. [Official] Tip Check above you in rooms with high ceilings. Boss ### The Mother Woken by a hidden ritual. Players report the route: collect three hearts, offer them at the Gun Ascension altar, enter her room. [Official] [Players] Tip Full route and prep in the Easter egg guide. ## How damage reads on enemies - Arms and legs come off where you shoot them. [Official] - Big guns punch holes straight through, so a line of zombies is a target, not a threat. [Official] - Bodies fall the way the bullet sent them, then bleed out, burn up or shatter depending on how they died — a hint at the elemental damage types. [Official] ## Not yet documented Health values, damage numbers, the rounds where each special first appears, and the other specials Steam refers to as “and more” have not been published. We list stats only when the developer publishes them or they can be reproduced reliably. ## FAQ **Q: What enemies are in Mortuus?** Regular zombies (which chase, flank or cut you off), plus later-round specials named on Steam: the Juggernaut, the Lope (runs on its arms) and the Skitter (crawls across the ceiling). There are also boss fights, including the Mother. **Q: Who is the Mother in Mortuus?** A boss woken by the hidden ritual described on the Steam page. Players report reaching her by offering three hearts at the Gun Ascension altar. ## Sources Labels: [Official] store page or pinned post · [Dev] developer statement · [Players] community report, not confirmed by the developer · [Press] coverage. - [Official] [Mortuus — Steam store page (app 3680170)](https://store.steampowered.com/app/3680170/Mortuus/) — 2026-10-29 - [Players] [Community thread: "通關方式" (how to clear the demo)](https://steamcommunity.com/app/3680170/discussions/0/567049339876318931/) — 2026-10 - [Press] [MeinMMO — Steam Next Fest October 2026 top 10 (German)](https://mein-mmo.de/steam-next-fest-oktober-2026-top-10/9/) — 2026-10 Spotted something outdated?

See [how we source](https://mortuusgame.com/about/). --- # Weapons URL: https://mortuusgame.com/wiki/weapons/ Last verified: 2026-10-29 Key facts Mortuus has over 30 guns. [Official] You get them off the wall, from the Mystery Box [Official], or bring them in your loadout [Players]. You upgrade them at the Gun Ascension altar. [Official] More weapons are planned after launch. [Official] ## Getting guns ### Wall weapons “Take a gun off the wall.” [Official] Players report there’s a wall buy in every room, and that they appear as a light grey weapon outline on the wall — easy to miss on grey concrete. [Players] ### Mystery Box “Hit the mystery box.” [Official] It moves every run along with the rest of the map. [Official] Odds and its weapon pool haven’t been published. ### Loadout Between runs, players pick a loadout whose total cost is paid from money banked in earlier runs. Unlocked items still cost bank money each time you equip them. [Players] See [Levels, bank & loadouts](https://mortuusgame.com/wiki/progression/). ## Upgrading guns Feed your gun to the [Gun Ascension](https://mortuusgame.com/wiki/perks-and-upgrades/#gun-ascension) altar and choose how it gets stronger, as many times as you can afford. [Official] Round-end drafts add more: players cite headshot multipliers, extra ammo, fire-rate increases, infinite ammo, lightning damage and a cash bonus. [Players] [Dev] [Players] ## Weapons players name most Player reports, demo buildNo official weapon list has been published. These names come from Steam discussions; stats are players’ claims and balance can change before launch. | Weapon | Type | What players say | | PKM | Machine gun | Called the “subjectively best weapon” by one player: with two headshot upgrades it one-shots normal zombies; three ammo upgrades push it to nearly 900 rounds with 196 in the mag. Map makers ban it as an “overtuned” wall buy. [Players] [Official] | | Bizon | SMG | Named alongside the PKM as an “overtuned” wall buy that challenge maps remove. [Official] | | UMP | SMG | A player reports one-shot headshots with it until the end of round 26. [Players] | | Rebar | — | Appears in a player bug report about its reload. Type not documented. [Players] | | M9 | Pistol | Listed in coverage of the trailer as a wall-outline buy. [Press] | | Knife | Melee | One-hits early zombies; needs more hits from round 6+ unless a melee upgrade rolls. Players debate whether it’s too strong with the melee perk. [Players] | ## Wonder weapons A player answering “will there be wonder weapons” says there’s already one in the demo, and expects more with launch and the map editor. [Players] It has not been named officially. The pinned FAQ confirms more weapons are coming, possibly including community suggestions. [Official] ## FAQ **Q: How many guns are in Mortuus?** Over 30, according to the Steam page, with more weapons planned after launch per the pinned FAQ. **Q: What is the best gun in Mortuus?** Players most often name the PKM and the Bizon as overpowered wall buys, and the UMP for headshots. Balance can change before the January 2027 release. **Q: Are there wonder weapons in Mortuus?** A player says one already exists in the demo; it hasn’t been named officially. ## Sources Labels: [Official] store page or pinned post · [Dev] developer statement · [Players] community report, not confirmed by the developer · [Press] coverage. - [Official] [Mortuus — Steam store page (app 3680170)](https://store.steampowered.com/app/3680170/Mortuus/) — 2026-10-29 - [Official] [Pinned "Mortuus | Frequently Asked Questions" — Steam discussions](https://steamcommunity.com/app/3680170/discussions/0/567049623178348498/) — 2026-10-27 - [Players] [Community thread: "Took 1 hour to find the first generator room"](https://steamcommunity.com/app/3680170/discussions/0/567049339876261804/) — 2026-10-24 - [Players] [Community thread: "the subjectively best weapon"](https://steamcommunity.com/app/3680170/discussions/0/562546073917287966/) — 2026-10-28 - [Official] [Pinned "Workshop Maps | Share Your Creations" — Steam discussions](https://steamcommunity.com/app/3680170/discussions/0/567049039351201180/) — 2026-10-21 - [Players] [Community thread: "little bit of feedback after playing" (knife)](https://steamcommunity.com/app/3680170/discussions/0/569300439979305166/) — 2026-10 - [Players] [Community thread: "will there be wonder weapons"](https://steamcommunity.com/app/3680170/discussions/0/562546073917194651/) — 2026-10-27 - [Players] [Community thread: "Not a Fan of Banking Being Limited"](https://steamcommunity.com/app/3680170/discussions/0/567049339876206328/) — 2026-10 - [Players] [Community thread: "No" (difficulty scaling discussion)](https://steamcommunity.com/app/3680170/discussions/0/567049339876338185/) — 2026-10-25 - [Players] [Community thread: "Rebar reload issue/bug"](https://steamcommunity.com/app/3680170/discussions/0/567049339876275672/) — 2026-10 - [Press] [Venn Studios — Mortuus curator notes (trailer breakdown)](https://www.venn-studios.com/research/curator/mortuus/) — 2026-10-21 - [Dev] [Developer (Hamuno) replies in "constant freezing and low fps"](https://steamcommunity.com/app/3680170/discussions/0/567049039351148172/) — 2026-10 Spotted something outdated? Mortuus is still in development; values can change between demo patches and the full release. See [how we source](https://mortuusgame.com/about/). --- # Perks, Ascension & upgrades URL: https://mortuusgame.com/wiki/perks-and-upgrades/ Last verified: 2026-10-29 Four layers - Perks — bought from machines scattered across the map. [Official] - Gun Ascension — feed your gun to the altar and choose how it gets stronger, repeatable as long as you can pay. [Official] - Upgrade draft — pick one upgrade after every round. [Official] - Elements — five of them, per Steam. [Official] ## Perks Perk machines are scattered around the map and, like everything else, move every run. [Official] No official perk list exists yet. Perks players mention by name: - Second Chance — strong enough that challenge-map makers remove it. [Official] - Melee perk — players say it makes the knife very strong early. [Players] ### Vending machines Separate from perk machines: map makers describe vending machines as a source of stat boosts alongside level-ups. [Official] ## Gun Ascension Find itThe Ascension room has a purple/violet lamp above its door. [Players] “Feed your gun to the Gun Ascension altar and choose how it gets stronger, as many times as you can afford.” [Official] Two practical consequences: - Commit to one gun. Repeated Ascensions compound, so spreading points across guns weakens you. - The altar matters twice. Players offer the three hearts here for the [Easter egg](https://mortuusgame.com/guides/easter-egg/). Ascension costs and the exact upgrade options haven’t been published. ## Upgrade draft After every round, pick one upgrade from a draft — so each run builds differently. [Official] Demo coverage describes a choice of three, picked by each player individually. [Press] ### Draft options players report | Upgrade | Notes | Source | | Headshot damage multiplier | A player runs two on the PKM to one-shot normal zombies | [Players] | | Ammo capacity | Three stacks reportedly push the PKM to ~900 reserve / 196 mag | [Players] | | Rate of fire increase | Mentioned in a performance report with lightning damage | [Dev] | | Infinite ammo | Same report; players say free ammo makes runs much easier | [Dev] | | Lightning damage | An elemental effect players name | [Dev] | | Cash bonus | Boosts money earned; players use it to bank faster | [Players] | | Melee upgrade | Keeps the knife viable past round 6 | [Players] | | Hollow-point damage | Shown as an upgrade choice in trailer coverage | [Press] | Names are paraphrased from player posts; in-game wording may differ. Players also note that almost every upgrade in the demo is locked to the full game. [Players] ## The five elements Steam lists “Five elements” as a key feature, without naming them. [Official] What we can say: - Players mention lightning damage. [Dev] - The store says bodies “bleed out, burn up or shatter depending on how they died.” [Official] Which element causes which effect isn’t documented. We’ll list all five once they’re named officially or confirmed in-game. ## FAQ **Q: What is Gun Ascension in Mortuus?** An altar where you feed your gun and choose how it gets stronger. You can repeat it as many times as you can afford. Its room is marked by a violet/purple lamp. **Q: How does the upgrade draft work in Mortuus?** After every round you pick one upgrade from a draft. Coverage of the demo describes a choice of three, picked by each player individually in co-op. **Q: What perks are in Mortuus?** Perks are bought from machines scattered across the map. There is no official list yet; players mention a Second Chance perk and a melee perk, plus separate vending machines that give stat boosts. **Q: What are the five elements in Mortuus?** Steam confirms five elements but hasn’t named them. Players mention lightning damage, and the store notes bodies can bleed out, burn up or shatter depending on how they died. ## Sources Labels: [Official] store page or pinned post · [Dev] developer statement · [Players] community report, not confirmed by the developer · [Press] coverage. - [Official] [Mortuus — Steam store page (app 3680170)](https://store.steampowered.com/app/3680170/Mortuus/) — 2026-10-29 - [Players] [Community thread: "Took 1 hour to find the first generator room"](https://steamcommunity.com/app/3680170/discussions/0/567049339876261804/) — 2026-10-24 - [Press] [gaming-st.com — Mortuus demo guide: Japanese, co-op, PC specs (Japanese)](https://gaming-st.com/pc-games/mortuus-demo-japanese-coop-pc-specs/) — 2026-10 - [Official] [Pinned "Workshop Maps | Share Your Creations" — Steam discussions](https://steamcommunity.com/app/3680170/discussions/0/567049039351201180/) — 2026-10-21 - [Players] [Community thread: "little bit of feedback after playing" (knife)](https://steamcommunity.com/app/3680170/discussions/0/569300439979305166/) — 2026-10 - [Players] [Community thread: "the subjectively best weapon"](https://steamcommunity.com/app/3680170/discussions/0/562546073917287966/) — 2026-10-28 - [Dev] [Developer (Hamuno) replies in "constant freezing and low fps"](https://steamcommunity.com/app/3680170/discussions/0/567049039351148172/) — 2026-10 - [Players] [Community thread: "Not a Fan of Banking Being Limited"](https://steamcommunity.com/app/3680170/discussions/0/567049339876206328/) — 2026-10 - [Press] [Venn Studios — Mortuus curator notes (trailer breakdown)](https://www.venn-studios.com/research/curator/mortuus/) — 2026-10-21 - [Players] [Community thread: "progress"](https://steamcommunity.com/app/3680170/discussions/0/567049339876359200/) — 2026-10 Spotted something outdated?

[Players] Most unlocks are locked to the full game in the demo, and demo progress will not transfer to the full release. [Players] [Official] ## Levels & XP Players reach level 17–20 after only a few runs, and believe the demo grants boosted XP (one estimate: 3×). [Players] Treat demo levels as a preview — they reset at launch. [Official] ## Banked money - Money earned in a run goes into a bank shown in the top-right of the loadout screen. [Players] - Players say banking “hundreds of thousands” is easy; one reports over 26k from an hour of solo play. [Players] - Fastest method players cite: a fast-firing weapon on the torso, plus the cash-bonus upgrade. [Players] ## Loadout cost Your loadout shows a total cost (top-left) paid from your bank. Unlocking an item costs money, and equipping it costs again each run — a design some players dislike and others defend as a way to start runs with a build already in mind. [Players] The UI may not update when you no longer afford a selected item.

Banking hundreds of thousands is reportedly easy. **Q: Will Mortuus have a skill tree?** Press coverage of the demo says the full version adds meta-progression through a skill tree.

Our guides teach signals and systems that stay constant, cite where each fact comes from and say plainly when something is unknown. Advice that is our own reasoning, not a sourced fact, carries no source label. ## Sources Labels: [Official] store page or pinned post · [Dev] developer statement · [Players] community report, not confirmed by the developer · [Press] coverage. - [Official] [Mortuus — Steam store page (app 3680170)](https://store.steampowered.com/app/3680170/Mortuus/) — 2026-10-29 - [Official] [Mortuus Demo — Steam store page (app 5363350)](https://store.steampowered.com/app/5363350/Mortuus_Demo/) — 2026-10-29 Spotted something outdated?

After every round, draft upgrades that support that gun. Keep a loop route to kite crowds. In the demo, the run caps at round 25, where you can vote for “just one more round.” [Official] [Players] [Players] ## The loop, in one line Survive the round → spend your points → choose your upgrade → repeat. [Official] Points go on doors, debris clearance, wall guns, Mystery Box spins, perks and Ascension. Every purchase competes with the others, so a plan matters. ## Rounds 1–5: get a gun, start opening - Earn efficiently. Fighting zombies earns your points. Players report that a fast-firing gun aimed at the torso earns a lot of money. [Players] - The knife is strong early. Players find it one-hits early zombies, but by round 6+ it needs more than one hit unless you have a melee upgrade. [Players] - Buy a wall gun. There is reportedly a wall-buy weapon in every room. [Players] - Open toward unexplored space. Buy doors and clear debris. [Official] ## Rounds 5–12: power, perks, Ascension - Turn on the power. Follow the red lamp — full walkthrough in [How to turn on the power](https://mortuusgame.com/guides/power/). - Buy perks from machines scattered across the map. [Official] - Start Ascending. Feed your gun to the Gun Ascension altar and choose how it gets stronger — as many times as you can afford. [Official] - Draft with intent. One upgrade after every round. [Official] Pick upgrades that stack on the gun you’re Ascending. ## Rounds 12–25: specials and crowd control From early rounds some zombies chase you, some cut you off and some go around. Later the Juggernaut, Lope and Skitter join in — the Skitter comes across the ceiling. [Official] See [Enemies](https://mortuusgame.com/wiki/enemies/). - Shoot legs to slow threats. Leg shots make zombies crawl. [Official] - Look up. Skitters arrive from the ceiling. - Use penetration. Big guns punch holes straight through bodies. [Official] Line crowds up in corridors. - Keep a loop. A courtyard or a ring of rooms you can circle beats standing in a dead end. ## First-run checklist Tick as you go. Saved in this browser only. - Swap the pistol for a wall buy - Open doors toward unexplored space - Find the red lamp and turn on the power - Note where the violet lamp (Ascension) is - Buy your first perk - Ascend your main gun at least once - Draft for one clear build - Keep a loop route you can kite zombies around - Bank points for the late rounds - Reach round 25 Reset checklist ## After round 25 (demo) When you finish wave 25 in the demo, the team can vote “JUST ONE MORE ROUND” for a final wave. [Players] The full game is reported to have no round cap. [Press] ## FAQ **Q: Is Mortuus hard for beginners?** It follows familiar round-based zombies rules, so the loop is easy to pick up. The challenge is the random map: you have to find power and key rooms fresh every run. **Q: What should I buy first in Mortuus?** A wall gun to replace the pistol, then doors toward unexplored space until you find the power. Perks and Gun Ascension come after you have a stable route. **Q: Can you play Mortuus solo?** Yes. Mortuus supports single-player as well as online co-op for up to 4 players. ## Sources Labels: [Official] store page or pinned post · [Dev] developer statement · [Players] community report, not confirmed by the developer · [Press] coverage. - [Official] [Mortuus — Steam store page (app 3680170)](https://store.steampowered.com/app/3680170/Mortuus/) — 2026-10-29 - [Official] [Mortuus Demo — Steam store page (app 5363350)](https://store.steampowered.com/app/5363350/Mortuus_Demo/) — 2026-10-29 - [Players] [Community thread: "Took 1 hour to find the first generator room"](https://steamcommunity.com/app/3680170/discussions/0/567049339876261804/) — 2026-10-24 - [Players] [Community thread: "little bit of feedback after playing" (knife)](https://steamcommunity.com/app/3680170/discussions/0/569300439979305166/) — 2026-10 - [Players] [Community thread: "the subjectively best weapon"](https://steamcommunity.com/app/3680170/discussions/0/562546073917287966/) — 2026-10-28 - [Players] [Community thread: "Not a Fan of Banking Being Limited"](https://steamcommunity.com/app/3680170/discussions/0/567049339876206328/) — 2026-10 - [Players] [Community thread: "Can everyone vote to continue after wave 25?"](https://steamcommunity.com/app/3680170/discussions/0/562546073917271190/) — 2026-10-28 - [Press] [MeinMMO — Steam Next Fest October 2026 top 10 (German)](https://mein-mmo.de/steam-next-fest-oktober-2026-top-10/9/) — 2026-10 Spotted something outdated?

See [how we source](https://mortuusgame.com/about/). --- # Mortuus Easter egg: hearts & the Mother URL: https://mortuusgame.com/guides/easter-egg/ Last verified: 2026-10-29 Short answer Players report that killing zombies in certain rooms lets you collect hearts. Gather three, bring them to the Gun Ascension altar (violet lamp over the door) and offer them. That opens the Mother’s boss room. [Players] The Steam page confirms only that a hidden ritual wakes the Mother. [Official] The exact trigger rooms and the boss mechanics are not officially documented. ## What is confirmed - There is a hidden ritual that wakes the Mother, described on the official store page. [Official] - The game has special enemies and boss fights. [Official] - The October 20, 2026 demo patch added “a few hidden content things” the developer chose not to reveal, preferring they be “found naturally.” [Dev] - In the demo, a run ends at round 25 or when you reach the Easter egg / first boss. [Press] [Press] ## The hearts route (player-reported) Community reportThis route comes from a player answer in the official Steam discussions (originally in Chinese, translated here). We have not seen it confirmed by Hamuno. Treat specifics as provisional for the current demo build. - Open the map and turn on the powerNot proven to be required, but you will need points, a real gun and access to the wider map anyway. The power room sits behind the door with a red lamp. [Players] See [how to turn on the power](https://mortuusgame.com/guides/power/). - Locate the Gun Ascension roomIts door has a violet/purple lamp. [Players] Remember the route back — the layout is new every run. - Collect hearts from zombies in certain roomsThe report says that in some rooms, after killing zombies, you can collect a heart. [Players] Which rooms qualify is not documented; clear rooms methodically and watch for a pickup. - Collect three heartsThree is the number given in the report. [Players] - Offer them at the Ascension altarThe same altar you use to upgrade guns. [Players] - Enter the Mother’s roomThe offering is said to open access to the Mother boss room (“BOSS母體房”). [Players] Fight prepared — see below. ## How to prepare for the Mother No one has published boss numbers we can verify, so this is general preparation that follows from the confirmed systems: - Ascend your main gun first. The altar can be used repeatedly as long as you can afford it. [Official] Since the hearts go to the same altar, you’ll be there anyway. - Pick sustain in the draft. After every round you draft one upgrade [Official]; players mention picks like extra ammo and headshot damage on strong guns. [Players] See [upgrades](https://mortuusgame.com/wiki/perks-and-upgrades/). - Buy perks before the attempt. Perk machines are scattered around the map. [Official] - In co-op, assign roles. One player scouts rooms for hearts while others hold the horde. Doors you buy open for everyone. [Press] - Watch the round count in the demo. The run ends at round 25, so don’t leave the attempt too late. ## Still unknown | Question | Status | | Which rooms drop hearts | Not documented [Unknown] | | Whether power must be on first | Not documented [Unknown] | | The Mother’s attacks, phases and reward | Not documented [Unknown] | | Whether the full game changes the ritual | Not announced [Unknown] | | The rest of the hidden content added Oct 20 | Developer won’t reveal [Dev] | We will update this page when the developer or reproducible gameplay confirms more. We do not publish guessed numbers. ## Easter eggs on Workshop maps Custom maps built in the demo’s editor can hide their own Easter eggs — one creator’s office-themed map asks “Can you find the easter egg?” [Official] Those are separate from the official Mother ritual. See the [map editor guide](https://mortuusgame.com/guides/map-editor/). ## FAQ **Q: How many hearts do you need for the Mortuus Easter egg?** Three, according to the player report that first described the route in the official Steam discussions. The developer has not published official steps. **Q: Where do you put the hearts in Mortuus?** Players report offering them at the Gun Ascension altar — the room marked by a violet/purple lamp over its door. Doing so is said to open the Mother’s boss room. **Q: Does finishing the Easter egg end the demo?** Coverage of the demo says a run ends at round 25 or when you reach the Easter egg / first boss. The full game has no round cap planned. **Q: Is the Easter egg in the same place every run?** No fixed location exists because the map is procedurally generated each run. Use the door lamps (red = power, violet = Ascension) to orient yourself. ## Sources Labels: [Official] store page or pinned post · [Dev] developer statement · [Players] community report, not confirmed by the developer · [Press] coverage. - [Official] [Mortuus — Steam store page (app 3680170)](https://store.steampowered.com/app/3680170/Mortuus/) — 2026-10-29 - [Players] [Community thread: "通關方式" (how to clear the demo)](https://steamcommunity.com/app/3680170/discussions/0/567049339876318931/) — 2026-10 - [Dev] [Steam announcement: "DEMO Optimization Patch"](https://store.steampowered.com/news/app/3680170) — 2026-10-20 - [Players] [Community thread: "Took 1 hour to find the first generator room"](https://steamcommunity.com/app/3680170/discussions/0/567049339876261804/) — 2026-10-24 - [Press] [MeinMMO — Steam Next Fest October 2026 top 10 (German)](https://mein-mmo.de/steam-next-fest-oktober-2026-top-10/9/) — 2026-10 - [Press] [gaming-st.com — Mortuus demo guide: Japanese, co-op, PC specs (Japanese)](https://gaming-st.com/pc-games/mortuus-demo-japanese-coop-pc-specs/) — 2026-10 - [Official] [Pinned "Workshop Maps | Share Your Creations" — Steam discussions](https://steamcommunity.com/app/3680170/discussions/0/567049039351201180/) — 2026-10-21 - [Players] [Community thread: "the subjectively best weapon"](https://steamcommunity.com/app/3680170/discussions/0/562546073917287966/) — 2026-10-28 Spotted something outdated?

See [how we source](https://mortuusgame.com/about/). --- # How to turn on the power URL: https://mortuusgame.com/guides/power/ Last verified: 2026-10-29 Short answer Look for a door with a red light above it. Players say it is labelled “Door to Power” and leads to the generator room with the power switch. [Players] [Players] Buy doors and clear debris until you reach it. [Official] ## Why the power room moves between runs Every run builds a new procedurally generated map, so the doors, perk machines, Mystery Box and the way out are never where they were last time. [Official] Players confirm the generator hunt starts over each run. [Players] You can’t memorize a route. You learn to read signals instead. ## Fastest way to the power - Don’t stay on the pistolPlayers note there is a wall-buy weapon in every room. [Players] Swap as soon as you can afford one; it makes the hunt safer. - Open doors earlyBuying doors and clearing debris is how the map opens. [Official] Players say maps aren’t big and doors aren’t expensive. [Players] - Scan for the red lampThe power door “always has a red light above it.” [Players] Check above door frames as you enter each new space. - Ignore the violet lamp — for nowA purple light marks the Gun Ascension room. [Players] Note where it is; you’ll come back. - Flip the switch, then mark the routeRemember the turns back to the hub rooms. Layouts with repeating stairs and intersections are easy to get lost in, as players point out. [Players] TipExplore one branch at a time and back out of dead ends immediately. Courtyards and corridors repeat visually; count turns rather than trusting landmarks. ## Door lights at a glance | Light | Room | Why you care | | ■ Red | Door to Power / generator room [Players] | Turn on the power | | ■ Purple / violet | Gun Ascension room [Players] | Upgrade guns; players offer hearts here for the [Easter egg](https://mortuusgame.com/guides/easter-egg/) | ## What turning on the power does Steam’s description lists “find the power switch” as one of the core steps of opening the map. [Official] It does not spell out which machines need power, and we haven’t found a developer statement listing them. We won’t guess — if you’ve tested this, the [about page](https://mortuusgame.com/about/) explains how we verify reports. ## FAQ **Q: How do you turn on the power in Mortuus?** Buy doors and clear debris until you find the door with a red lamp above it — players say it is labelled “Door to Power.” The generator room is behind it; flip the power switch there. **Q: Why can’t I find the generator room in Mortuus?** The map is procedurally generated, so the power room moves every run. Follow the red lamp. Players also note the maps are not large and doors are not expensive, so open aggressively. **Q: What does the purple light mean in Mortuus?** A purple/violet lamp marks the Gun Ascension room, where you upgrade guns — not the power room. ## Sources Labels: [Official] store page or pinned post · [Dev] developer statement · [Players] community report, not confirmed by the developer · [Press] coverage. - [Official] [Mortuus — Steam store page (app 3680170)](https://store.steampowered.com/app/3680170/Mortuus/) — 2026-10-29 - [Players] [Community thread: "Took 1 hour to find the first generator room"](https://steamcommunity.com/app/3680170/discussions/0/567049339876261804/) — 2026-10-24 - [Players] [Community thread: "where is the generator room?"](https://steamcommunity.com/app/3680170/discussions/0/567049339876250872/) — 2026-10 Spotted something outdated?

Doors open for all, so one player funding a door helps everyone. Coordinate who pays. - Split roles on a fresh map. One scout hunts the red power lamp and the violet Ascension lamp while the others hold the spawn. - Diversify Ascension. Ascension and drafts are personal — build different weapons for crowd clearing and single-target damage. - Revive before you buy. A dead teammate is a lost gun on the line. ## Split-screen, crossplay & platforms - Split-screen / couch co-op: requested by players, not announced. [Not announced] - Platforms: Mortuus is a single Steam app for Windows, macOS and Linux with full controller support. [Official] No console versions have been announced; see [Platforms](https://mortuusgame.com/platforms/). - Family Sharing: supported, per Steam’s feature list. [Official] ## FAQ **Q: How many players can play Mortuus together?** Up to 4 players in online co-op. You can also play solo. **Q: Does the Mortuus demo have multiplayer?** Yes. The demo’s Steam page says it contains multiplayer co-op. **Q: Does Mortuus have split-screen?** Not announced. Players have asked for split-screen/couch co-op in the Steam discussions; Steam lists online co-op only. **Q: How do I invite friends in Mortuus?** Host a match from the multiplayer menu (public or friends-only lobby) and invite friends through Steam; friends can also accept a Steam invite or browse matches to join. ## Sources Labels: [Official] store page or pinned post · [Dev] developer statement · [Players] community report, not confirmed by the developer · [Press] coverage. - [Official] [Mortuus — Steam store page (app 3680170)](https://store.steampowered.com/app/3680170/Mortuus/) — 2026-10-29 - [Official] [Mortuus Demo — Steam store page (app 5363350)](https://store.steampowered.com/app/5363350/Mortuus_Demo/) — 2026-10-29 - [Press] [PlayCo-opGame — How to play Mortuus multiplayer](https://playco-opgame.com/how-to-multiplayer/mortuus/) — 2026-10 - [Press] [gaming-st.com — Mortuus demo guide: Japanese, co-op, PC specs (Japanese)](https://gaming-st.com/pc-games/mortuus-demo-japanese-coop-pc-specs/) — 2026-10 - [Players] [Community thread: "Can everyone vote to continue after wave 25?"](https://steamcommunity.com/app/3680170/discussions/0/562546073917271190/) — 2026-10-28 - [Official] [Pinned "Mortuus | Frequently Asked Questions" — Steam discussions](https://steamcommunity.com/app/3680170/discussions/0/567049623178348498/) — 2026-10-27 Spotted something outdated?

[Official] The editor is in the free demo. More tools and objects are planned, but they are not a high priority before launch. [Official] ## How to share your map - Publish to the Steam WorkshopYour map needs its own Workshop page before you can share it. [Official] - Copy the Workshop linkFrom your map’s Workshop page. [Official] - Post it in the pinned threadAdd name, difficulty, theme and unique features in “Workshop Maps | Share Your Creations.” [Official] Rules in that thread: the map must relate to Mortuus and follow Steam’s guidelines. [Official] Browse everything on the [Mortuus Workshop](https://steamcommunity.com/app/3680170/workshop/). ## Current editor limits - No bridge tool yet. Players fake bridges with props, but zombies won’t pathfind onto them. [Players] - Default assets only. Creators describe their maps as built “with default assets.” [Official] - Zombie rules aren’t editable yet. Customizing game rules is planned for the future. [Official] ## What’s planned | Feature | Status | | More editor features, tools, objects | Planned, low priority for now [Official] | | Custom game rules | Planned [Official] | | Full mod support (custom enemies, weapons) | Asked by players; no answer yet [Unknown] | ## Community maps to try From the pinned showcase thread.

[Official] It’s a useful signal of which pieces players consider strongest. ## FAQ **Q: Does Mortuus have a map editor?** Yes. The demo includes a Workshop map editor, and players are already publishing custom maps to the Steam Workshop. **Q: How do I share a Mortuus custom map?** Publish it to the Steam Workshop, copy the Workshop link and post it with a short description in the pinned “Workshop Maps | Share Your Creations” thread. **Q: Will the Mortuus map editor get more tools?** Yes — more features, tools and objects are planned, but the pinned FAQ says they are not a high priority right now. ## Sources Labels: [Official] store page or pinned post · [Dev] developer statement · [Players] community report, not confirmed by the developer · [Press] coverage. - [Official] [Pinned "Workshop Maps | Share Your Creations" — Steam discussions](https://steamcommunity.com/app/3680170/discussions/0/567049039351201180/) — 2026-10-21 - [Official] [Pinned "Mortuus | Frequently Asked Questions" — Steam discussions](https://steamcommunity.com/app/3680170/discussions/0/567049623178348498/) — 2026-10-27 - [Official] [Steam Workshop for Mortuus](https://steamcommunity.com/app/3680170/workshop/) - [Players] [Community thread: "How do I build a bridge?"](https://steamcommunity.com/app/3680170/discussions/0/562546073917312884/) — 2026-10-28 - [Players] [Community thread: "will there be wonder weapons"](https://steamcommunity.com/app/3680170/discussions/0/562546073917194651/) — 2026-10-27 Spotted something outdated?

See [how we source](https://mortuusgame.com/about/). --- # Performance & fixes URL: https://mortuusgame.com/guides/performance/ Last verified: 2026-10-29 Try these first - Update the demo — the Oct 20 patch fixed shaders not warming up, which caused effect and scope lag even on high-end PCs. [Dev] - Lower your mouse polling rate below ~2000 Hz if turning the camera stutters. [Dev] - Turn off in-game V-Sync/G-Sync and FPS limit and set them in your GPU control panel instead (player tip). [Dev] ## Camera stutter: mouse polling rate The developer explained that turning or looking around could feel like a lag spike, but it was actually an engine issue skipping inputs at polling rates around 2000 Hz and above. A fix was being published at the time. [Dev] If you still see it, drop your mouse to 1000 Hz in its software and retest. ## Effects and scopes lag: shader warm-up “Several players even on some higher end systems have had lag, specifically with some effects and scopes,” caused by shaders not being properly warmed up. The October 20, 2026 patch fixed it. [Dev] Let Steam finish updating the demo before testing again. ## Random freezing and frame drops - V-Sync / G-Sync / FPS cap: a player in the official thread recommends turning all of them off in-game and handling them globally in the NVIDIA app or your driver panel. [Dev] - Heavy scenes: players report drops with lots of zombies, gore, high ambient light, and stacked fire-rate and lightning effects. [Dev] Lower effects settings for late rounds. - Menu stutter: one player noticed hitching only when hovering the left-side buttons in the multiplayer lobby menu, not in-game. [Dev] ## Low-end PCs: potato mode is planned The developer says the optimization patch was aimed at low-end PCs and that a potato mode is planned, with “quite a big focus” before launch. [Dev] Check the [minimum requirements](https://mortuusgame.com/platforms/) — Steam lists a GTX 750 Ti-class GPU and 6 GB RAM for Windows. [Official] ## Antivirus flags (Kaspersky “Trojan”) The developer says the detection is a false positive: the executable is brand new and unsigned, sees heavy traffic and reports information like playtime and gun stats to backend servers, so it gets flagged. A Microsoft manual review was pending. [Dev] SafetyThis applies only to the copy installed through Steam. Never download Mortuus “demo” or “full game” files from other sites. We don’t host any game files. ## Linux: stuck on the title screen - Use the native Linux build, not Wine/Proton. [Players] - If it still fails, try Steam Linux Runtime 3 instead of the default runtime in the game’s compatibility settings. [Players] - Still stuck? The official Discord is where debugging happens. [Players] ## Steam Deck Players report the demo running smoothly on Steam Deck, even over hotel Wi-Fi in co-op. [Players] Mortuus has full controller support. [Official] ## FAQ **Q: Why does Mortuus lag when I turn the camera?** The developer traced one cause to high mouse polling rates (about 2000 Hz and up): an engine issue skipped inputs and felt like lag spikes. A fix was published; lowering polling rate is a quick test. **Q: Is the Mortuus demo a virus? My antivirus flagged it.** The developer says the flag is a false positive: the new, unsigned executable reports gameplay stats to its servers, and Microsoft review was pending. Download only from Steam. **Q: Does Mortuus run on Steam Deck?** Players report the demo runs smoothly on Steam Deck. Valve’s official Deck rating was not shown at the time we checked. **Q: Will Mortuus have a low-end mode?** Yes. The developer says a “potato mode” is planned before launch. ## Sources Labels: [Official] store page or pinned post · [Dev] developer statement · [Players] community report, not confirmed by the developer · [Press] coverage. - [Dev] [Steam announcement: "DEMO Optimization Patch"](https://store.steampowered.com/news/app/3680170) — 2026-10-20 - [Dev] [Developer (Hamuno) replies in "constant freezing and low fps"](https://steamcommunity.com/app/3680170/discussions/0/567049039351148172/) — 2026-10 - [Dev] [Developer (Hamuno) reply on antivirus false positives](https://steamcommunity.com/app/3680170/discussions/0/567049339876310406/) — 2026-10 - [Players] [Community thread: Linux title-screen issue](https://steamcommunity.com/app/3680170/discussions/0/562546073917204052/) — 2026-10-27 - [Players] [Community thread: "Steam Deck Compatible"](https://steamcommunity.com/app/3680170/discussions/0/567049039351401986/) — 2026-10 - [Official] [Mortuus — Steam store page (app 3680170)](https://store.steampowered.com/app/3680170/Mortuus/) — 2026-10-29 Spotted something outdated?

See [how we source](https://mortuusgame.com/about/). --- # Mortuus FAQ URL: https://mortuusgame.com/faq/ Last verified: 2026-10-29 ## The game ### What is Mortuus? A round-based co-op zombies FPS for 1–4 players by Hamuno. Every run builds a new procedurally generated brutalist map. You buy doors, find the power, take guns from walls or the Mystery Box, buy perks, upgrade guns at the Gun Ascension altar and draft one upgrade per round. ### Who makes Mortuus? Hamuno is listed on Steam as both developer and publisher. ### Is Mortuus like Call of Duty Zombies? Players and press compare it to CoD Zombies’ round-based formula. The big difference is the map: Mortuus generates a new one every run instead of using fixed maps. ### How many guns are in Mortuus? Over 30 per Steam, with more weapons planned after launch. ## Release & price ### When does Mortuus release? January 11, 2027, on Steam ([details](https://mortuusgame.com/release-date/)). ### How much is Mortuus? Planned price $14.99; a $19.99 Supporter Pack is being considered; launch discount for the first few weeks; no pre-orders. ### Is there a Mortuus demo? Yes, free on Steam since October 14, 2026, with co-op and the map editor. It caps runs at round 25 and goes offline about 1–2 weeks before launch ([demo guide](https://mortuusgame.com/demo/)). ### Does demo progress carry over? No. Stats, levels and other demo progress will not transfer to the full release. ## Platforms ### Is Mortuus on Xbox or PS5? No console version has been announced. Steam lists Windows, macOS and Linux ([platforms](https://mortuusgame.com/platforms/)). ### Does Mortuus run on Steam Deck? Valve hasn’t rated it, but players report the demo runs smoothly on Deck. It has full controller support. ### Does Mortuus have split-screen? Not announced; it supports online co-op only. ## Gameplay ### How do I turn on the power? Find the door with a red light above it (players say it’s labelled “Door to Power”) and flip the switch in the generator room ([power guide](https://mortuusgame.com/guides/power/)). ### How do I do the Easter egg? Players report collecting three hearts from zombies in certain rooms and offering them at the Gun Ascension altar to open the Mother’s boss room. Not officially confirmed ([Easter egg guide](https://mortuusgame.com/guides/easter-egg/)). ### What does the purple light mean? It marks the Gun Ascension room. ### Can you continue after round 25 in the demo? After wave 25 the team can vote “JUST ONE MORE ROUND” for one final wave. ### Can I make my own maps? Yes — the demo includes a map editor and maps are shared on the Steam Workshop ([map editor guide](https://mortuusgame.com/guides/map-editor/)). ## Technical ### Why does my antivirus flag Mortuus? The developer says it’s a false positive on a new, unsigned executable that reports gameplay stats; a Microsoft review was pending. Only install from Steam. ### Why does Mortuus stutter when I turn? High mouse polling rates (~2000 Hz+) triggered an engine input issue; the developer published a fix. Lowering polling rate is a quick test ([fixes](https://mortuusgame.com/guides/performance/)). ## Sources Labels: [Official] store page or pinned post · [Dev] developer statement · [Players] community report, not confirmed by the developer · [Press] coverage. - [Official] [Mortuus — Steam store page (app 3680170)](https://store.steampowered.com/app/3680170/Mortuus/) — 2026-10-29 - [Official] [Mortuus Demo — Steam store page (app 5363350)](https://store.steampowered.com/app/5363350/Mortuus_Demo/) — 2026-10-29 - [Dev] [Steam announcement: "Mortuus Release Date Revealed!!"](https://store.steampowered.com/news/app/3680170) — 2026-10-26 - [Official] [Pinned "Mortuus | Frequently Asked Questions" — Steam discussions](https://steamcommunity.com/app/3680170/discussions/0/567049623178348498/) — 2026-10-27 - [Players] [Community thread: "Took 1 hour to find the first generator room"](https://steamcommunity.com/app/3680170/discussions/0/567049339876261804/) — 2026-10-24 - [Players] [Community thread: "通關方式" (how to clear the demo)](https://steamcommunity.com/app/3680170/discussions/0/567049339876318931/) — 2026-10 - [Players] [Community thread: "Can everyone vote to continue after wave 25?"](https://steamcommunity.com/app/3680170/discussions/0/562546073917271190/) — 2026-10-28 - [Official] [Pinned "Workshop Maps | Share Your Creations" — Steam discussions](https://steamcommunity.com/app/3680170/discussions/0/567049039351201180/) — 2026-10-21 - [Dev] [Developer (Hamuno) reply on antivirus false positives](https://steamcommunity.com/app/3680170/discussions/0/567049339876310406/) — 2026-10 - [Dev] [Developer (Hamuno) replies in "constant freezing and low fps"](https://steamcommunity.com/app/3680170/discussions/0/567049039351148172/) — 2026-10 - [Players] [Community thread: "Steam Deck Compatible"](https://steamcommunity.com/app/3680170/discussions/0/567049039351401986/) — 2026-10 - [Press] [MeinMMO — Steam Next Fest October 2026 top 10 (German)](https://mein-mmo.de/steam-next-fest-oktober-2026-top-10/9/) — 2026-10 Spotted something outdated?
