Concrete Abyss

Concrete Abyss is a 1-4* player co-operative horror roguelite PvE extraction shooter. You are a Liquidator, a projected consciousness piloting a synthetic body, contracted by the Canadian Centre for Spatial Resonance following their investigation into localized spatial resonance anomalies.  
DESCEND
Explore the many sub-sectors of the K.D.V.R. Facility and complete your objectives each floor to unlock the elevator and continue your descent towards the source of the anomaly.
SCAVENGE
Once you're down there, you're on your own. Loot whatever you can find to craft supplies and ammo, or perhaps exchange it for other uses?
SURVIVE
Over years of neglect, K.D.V.R. is now overrun with a whole ecosystem of alien creatures, unnatural horrors that defy understanding, and K.D.V.R's own malfunctioning security AI.
THE CLOCK IS TICKING
The longer you stay in a sub-level, the more hostile the space gets: increased enemy presence, the world bending around you, and the security AI growing more frustrated with your continued intrusion.

*The game is intended for a maximum of 4 players, however inquisitive liquidators will be able to increase this limit without external tools.
