The first co-op horror extraction game on mobile, with full PC cross-play. Squad up, loot cursed ruins, escape alive — and try not to die laughing. CO-OP HORROR EXTRACTION — NOW ON MOBILE The horror extraction genre finally comes to your phone, and it's finally fun for everyone. No hardcore grind. No steep learning curve. Just you, your friends, and a cursed ancient ruin full of things that want to eat you. Drop in with up to 4 players, loot cursed tombs, and extract before ancient horrors end your run. Go deeper for rarer relics, but push too far and you lose everything. SCARY ALONE. HILARIOUS TOGETHER. Solo? Genuinely terrifying. With friends? Pure chaos. Play on mobile or PC with full cross-play — your squad, your platform. Proximity voice chat turns every run into unscripted comedy. Dance in front of the boss. Watch your friend's ridiculous death replay on loop. Panic-scream a warning that comes three seconds too late. Oh, and one of your "teammates" might not be human. 20+ MONSTERS FROM FOLKLORE YOU'VE NEVER HEARD OF Every creature comes from ancient Eastern supernatural legends — each with its own origin story, skill, and weakness. The Ghost Bride hunts only one player — and only that player can see her. The Puppet copies your teammate's voice to lure you in. Fight them, outsmart them — or capture them alive. PICK YOUR ROLE. OWN YOUR STYLE. Choose your character — Explorer, Supporter, Fighter — each with a unique playstyle. Then dress them however you want. Tactical gear, elegant maid outfits, wacky headgear so weird even ghosts step aside. Your role, your look. EVERY RUN HITS DIFFERENT Randomized maps, traps, loot, and monster spawns. Dynamic conditions shifts mid-raid — blood moons, dense fog, solar eclipses — each changing how monsters behave. No two runs play the same.
