The Callisto Protocol Deluxe Edition Steam Altergift

Survival horror on a dead moon

The Callisto Protocol drops players into Black Iron Prison, a maximum-security facility on Jupiter's moon Callisto, three centuries from now. Jacob Lee, an inmate caught up in a sudden outbreak, must fight through transformed prisoners and hidden horrors to escape, uncovering what the United Jupiter Company has been hiding beneath the surface along the way.

Combat mixes close-quarters brutality with ranged weapons and a gravity tool once used to control the prison population, forcing players to adapt as the creatures they face keep evolving. Scavenging for weapons, gear and abilities is essential to staying ahead of the threat as Jacob works his way through Black Iron Prison and out onto the moon itself.
