A co-op survival horror shooter against an AI that learns from your actions. It grows more dangerous, relentlessly hunts you, and turns mistakes into deadly traps. Hide, hack security systems, and work together to survive.
Protocol:Terminate
Steam
The future where humanity no longer fights its own wars. Battles are waged by machines - self-learning AIs deciding who wins and who falls. But within the chaos of conflict, "anomalous behavior" is becoming more common - robots gaining consciousness and playing by their own rules. You are Debuggers. People without a past or a future. Your mission is to suppress the "awakened" machines, cover up the truth, and uphold the myth of AI infallibility. But in a world where Legionnaires learn, evolve, and begin to see humans as an obstacle... how much time does humanity really have left?

Play together in a squad of up to 4 players. Work as a team: cover each other, hack terminals, distract enemies, and fight your way out alive. Every mistake has a cost - survival is only possible together.

Your enemy is not a scripted machine but a living hunter. The robot learns, analyzes your actions, and adapts to your team’s tactics. It may seem slow as it stalks the corridors, but soon it will know exactly where you’re hiding. Every encounter is unique. Every clash more dangerous than the last.

Sometimes pulling the trigger is the worst choice. Hide in cover, distract the enemy with noise, cut the lights, and use the environment to stay unseen. But remember: the robot hears everything you hear. Get too close - and it’s fatal.

Build your loadout to match your playstyle. Attachments, sights, stocks, and more gear to fine-tune your weapons. Perks and upgrades for your PDA: hacking, traps, improved combat efficiency. Each build unlocks new ways to play and makes your team unique - every session unforgettable.
