›Story

INFERNO PROTOCOL takes place in a vast and deadly labyrinth that supports up to 6 players, spanning an enormous area roughly equivalent to 22,000 football fields. Every corner of this structure is different, confronting you with mind-bending situations. The most important rule to reaching the exit is simple: survive.

You don’t know why you’re here or who brought you. All you know is that something is deeply wrong with this massive structure. Curved walls, impossible corridors, and an unexplainable atmosphere… this place exists to test you. You are trapped in this cage with no map and no rescue team. Use every tool at your disposal to mark your path and escape this madness.
