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.
Upgrading guns
Feed your gun to the 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

| M9 | Pistol | Listed in coverage of the trailer as a wall-outline buy. Press |
