Fell out of the sky onto a rooftop. No idea why. The building goes down and it doesn't stop. Something's always watching, there's a mouth on the roof, and nothing makes sense. Figure it out alone or bring friends if you want but they're gonna die too. Good luck

SUBFLOOR is a co-op horror game where you and your friends descend into a procedurally generated building full of things that want you dead.
You fell out of the sky onto a rooftop. There's a mouth up here. It's hungry. The only way forward is down - floor after floor of dark rooms in a building that's never the same twice.
No weapons. No fighting back. Your only defense is folding into a cube and hoping whatever's in the room moves on.
Entities lurk below. Some hunt by sound. Some hunt by sight. One kills you just for looking at it. One only moves when you're not watching. Learn how they work or don't - they're gonna find you either way.
Scavenge junk from every cabinet, drawer, and shelf you can find. Bring it back to the roof. Feed the mouth. Use what you earn to upgrade your light source, you might lose it though if you're not careful
Every run is different. Every floor gets worse. Play solo if you're brave or bring up to 3 friends if you want witnesses.
Nothing down there makes sense. That's the point.
