01 / QUICK CHECK
Check these before the elevator drops
Elevator symbolsThe elevator symbols are floor modifiers that change economy, utility, exit conditions or danger. A launch-week player guide observed 15 effects, but this is not an official pixel-perfect icon atlas and current in-game labels remain authoritative.Squad sizeGRAIN ROT supports solo and online co-op. A FAQ posted by u/grainrotofficial says a lobby can support as many survivors as the host setup can handle, while the game is balanced and best played with around four. Each participant needs a copy.Enemy field notesFor a Corrupted Elite, two Steam discussions independently place the first chance around floor 5; one says Elite Rooms become more common near level 10. These are community reports, not a guaranteed spawn formula.Fuse repairsWhen the elevator rolls a missing or blown fuse, search nearby boxes, lockers and toolboxes, carry the fuse to the elevator panel, insert it, and confirm return power before starting a long loot route.
