When tension runs high and suspicions rise, even reviving your teammates might come at a cost.Choose wisely. Your survival depends not just on what you do… but who you trust.And while you search, something else hunts.Entities roam the facility and forest beyond. They stalk, hunt, and listen.

Your survival depends not just on what you do… but who you trust—and what you can’t hear coming.Core FeaturesHidden Traitor Mechanic One of you has been compromised. Assigned a secret role, they walk among the team—pretending to help while secretly working against you. Only they know who they are. And only they can unleash what they’ve become.Voice-Based Horror Proximity voice chat is your only lifeline—but it’s unreliable. The entities hear everything. They mimic your voice, replay screams, and distort words to confuse and isolate. What you hear can’t always be trusted.Atmospheric, Shifting Environment Explore a massive facility tangled in overgrowth and paranoia. From decaying bunkers to fog-drenched trails, the deeper you go, the more unstable everything feels—like the map itself doesn’t want you to leave.Entity-Driven Fear You’re not just being watched. Entities stalk, hunt, and learn from your voice. Some follow. Some mimic. Others twist your perception entirely. Whether AI or something worse, they’re always listening—and always getting closer.Risk-Reward Revival System Collect five portal components to escape. But at any point, the team can spend one to revive the dead—even if that means bringing the saboteur back. Every decision has consequences. Who do you really want to save?Unpredictable Multiplayer Horror For 2–8 players. Each session brings new scares, new traitors, new tricks. Randomized roles, dynamic AI behaviour, and voice-based deception ensure no run plays the same twice.Replayable TensionNo two sessions are ever the same. A hidden saboteur, unpredictable AI entities, voice-driven deception, and risk-heavy revival choices ensure every match unravels differently. Trust breaks, alliances shift, and fear evolves—run after run.
