About The Callisto Protocol
The Callisto Protocol is a third-person survival horror game set in 2320, 300 years in the future. You play as Jacob Lee, an inmate at Black Iron Prison, a maximum-security penitentiary on Jupiter’s moon Callisto. When a mysterious outbreak turns inmates into monstrous creatures and throws the prison into chaos, Jacob must fight his way to safety while uncovering the secrets beneath the moon’s surface and the mysteries surrounding the United Jupiter Company.
Combat and survival
You combine ranged weapons with close-quarters combat against rapidly evolving creatures. A gravity weapon once used by Black Iron’s guards lets you control your opponents; you can also attack at close range, hack off limbs and blast off legs. Scavenging helps you unlock weapons, gear and abilities as you try to escape the growing threat.
Callisto and Black Iron
Jacob’s struggle takes place in the isolated, hostile environment of Jupiter’s dead moon. The horrors of Black Iron Prison and the centuries-old secrets that haunt Callisto lie both above and below its surface.
Gore Skin Collection
The game also includes the Gore Skin Collection.
