Sector Null

Every Run is Different The sub-surface layout changes every time you play. You'll navigate through up to 250 procedurally generated rooms per run - ranging from reactor chambers and server hubs with blinking LED grids, to creaking metal walkways hanging over a bottomless void.

Fight the Infection, or Lose Your Mind The virus isn't just a status bar. As your corruption levels spike, your vision distorts and the environment begins to warp. Keep your head together, because reaching maximum corruption means losing your mind entirely. However, some alternate paths out of the facility might require you to embrace the rot.

Get Your Hands Dirty on the Terminals You can't just run to the exit. You’ll have to physically interact with industrial systems to escape. Replace blown server fuses, vent steam pressure valves, reboot corrupted memory cores, and drain pools of acid or radioactive waste to clear your path.

Conserve Your Energy, or Stay Silent Resources are scarce. Your flashlight battery is constantly draining. Sometimes, staying crouched in the shadows is your only way to survive the Crawlers, Watchers, and whatever else is stalking you from the abyss.

Permanent Upgrades Surviving runs and unlocking achievements gets you coins. Spend them in the shop to permanently upgrade your character for future attempts: buy the Glock, increase your run speed, make your flashlight batteries last longer, or boost your health and stamina.

15 Achievements, Multiple Endings How will you get out? Escaping normally is just one option. You can overload the nuclear reactor, isolate yourself in quarantine to save the surface, yield to VERA’s suspicious demands, or even manage a bizarre symbiosis with the creatures. Find all the endings and unlock the ultimate achievements.
