Enter the blackest regions of space where hell awaits. The Callisto Protocol is a third-person survival horror game that pits you against the unspeakable horror of an alien invasion while you are trapped in a prison facility. Play as Jacob Lee, a man in the worst place at the worst time. You’ve been thrown into the maximum security penitentiary Black Iron Prison, located on the hostile surface of Jupiter’s moon, Callisto. But something has gone horribly wrong. Due to the machinations of the prison warden, alien biophages have infiltrated the base, turning humans into hideous flesh-eating monsters. What was once a prison is now a massive deathtrap where only the most steadfast of wills can survive.
Made by the creator of Dead Space, The Callisto Protocol ups the ante on survival games with its gut-wrenching body horror and updated survival mechanics. Face horrific, misshapen creatures composed of fused faces, writhing tentacles, and rows of sharp teeth. You must also contend with mechanical foes, as the security robots will terminate any attempt to escape with extreme prejudice.
You can be versatile in combat: choose between guns or close combat. You can also employ a device that manipulates gravity. You can also improve your gear using workbenches scattered around the facility.
Use everything that can give you an edge. Fight where you must, run and hide where you can. The monsters of The Callisto Protocol won’t spare a second in making you their next meal.
