Map editor & Workshop

Beyond the random maps, Mortuus lets anyone build their own. The demo already includes the editor — and the Workshop is filling up.

Guide Verified Applies to Demo (Steam app 5363350), after the Oct 20, 2026 optimization patch
Short answer

“In Mortuus, everyone has the opportunity to create their own maps,” and maps are shared through the Steam Workshop. 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

  1. Publish to the Steam WorkshopYour map needs its own Workshop page before you can share it. Official
  2. Copy the Workshop linkFrom your map’s Workshop page. Official
  3. 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.

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

Community maps to try

From the pinned showcase thread. Official Descriptions are the creators’ own claims; links open Steam.

MapCreator’s pitch
The PyramidRed, horror-inspired; a central pyramid linked to spawn by one hallway. Medium–hard.
Escape the FacilityUnderground lab escape. Medium; 2–4 players recommended.
Site 19 | SCP-173 ContainmentSmall–medium containment facility.
Outdoor Arena – NightTwo rooms plus power and Ascension; built for XP and practice.
The OfficeOffice-themed, 4 players suggested — with its own Easter egg.
Hotel LancasterPush deeper into the hotel to unlock weapons and upgrades.
Alley ChallengeOne room of alleys; no Ascension, no Second Chance perk, no overtuned wall buys.
Staircase ChallengeNo Ascension or Second Chance; stats only from level-ups and vending machines.

Design notes from the challenge maps

Creators balance maps by removing systems: challenge maps drop Gun Ascension, the Second Chance perk and “overtuned” wall buys such as the Bizon and PKM, leaving vending machines and level-ups as the only stat sources. Official It’s a useful signal of which pieces players consider strongest.
