About the Game

Descend floor by floor through an abandoned building where every elevator takes you to a new level to explore. Grab what you can, avoid what you must, and make it back up alive.

The Elevator


It all starts here. Pick your floor, step into the elevator, and begin the descent alongside the other players.

Explore Together


Play solo or with up to 6 players online. Every floor is randomly generated, so no one knows what's waiting ahead. Each level also hides its own mini-games to take on, but stay sharp: traps and enemies are lurking around every corner. With more players, you cover more ground, share the risks, and usually come out better off.

End of the Run


Once the descent is over, a machine inside the elevator lets you trade everything you've collected for cash, with a board displaying your earnings. It's time to take stock of the expedition before heading back up.

The Lobby


Between runs, your lobby serves as your base. Sell what you've found, customize the space, and gear up for the next expedition.
