The rich live underground. Safe. Shielded. Climate-controlled.

You live at the top, where the sun can kill you.

They call you Penthouse Rats. Useful bacteria. Every shift, you and your crew descend into the ruins of the old world to scavenge scrap for the machines below. The quota must be met. The creatures are waiting. And there is no safe way to move.

THE NOISE PARADOX One creature hunts sound: your footsteps, your gunshots, your voice. Another feeds on silence - stand still and it reads you as prey. When both are present, there is no safe behavior. You must constantly choose between two threats.

SMART CREATURES. EACH ONE HUNTS DIFFERENTLY Every creature on the surface has its own AI behavior and counterplay. One mimics your teammates. One grabs you and throws you across the room. One blinds you. One only moves when you're not looking. One holds you still while others close in. Learn every single one, or become what you're here to collect.

PROCEDURALLY GENERATED DUNGEONS Three distinct locations, a rusted carnival, a dead factory, and a forgotten subway. The layout reshuffles every run. Landmines. Turrets. Locked doors. Radiation surges. No two shifts are the same.

PROXIMITY VOICE CHAT Your voice carries through the corridors. Scream for help and your crew hears you, but so does everything else. Whisper to survive. Coordinate to extract. Trust no one who sounds like your friend.

MEET THE QUOTA, OR ELSE Scavenge valuable scrap from the ruins of human civilization. Dodge traps and creatures. Extract before the radiation surge hits. Sell enough to satisfy the machines that run what's left of the world. Fall short, and there won't be a next shift.
