Backrooms: Overstay

Backrooms: Overstay is a co-op survival horror game set in an endless, procedurally generated Backrooms. Explore, scavenge, and survive solo or with up to 8 players while you search for the way out.

• Endless procedural levels. The yellow, humming Level 0 generates endlessly around you, with no edges and nothing repeating. Every run is seeded, so share a seed to play the same map with friends.
  
• Stealth against four hunters. Each enemy hunts differently and has a weakness you learn: stay unlit, stay quiet, or stay out of sight. Weapons only stagger them, so running and hiding beat fighting.
  
• Survival and sanity. Manage hunger, thirst, stamina, warmth, and health. Rising stress brings hallucinations and false sounds.
  
• Craft and build. Gather materials, unlock blueprints, build and reinforce a shelter, set traps, and crawl into the vent network to break line of sight.
  
• 8-player online co-op. Positional proximity voice chat the monsters can hear, plus solo play and optional PvP.
  
• Your rules. Calm, Normal, or Cruel difficulty, optional permadeath, and a real goal: reach the exit and escape, or get kept forever.
