About the base game:

The Callisto Protocol is a survival horror game directed by Glen Schofield, a co-creator of the iconic Dead Space series. Once again, he sends players to outer space. You'll play as Jacob Lee, an inmate of Black Iron Prison, a maximum-security compound built on the second-largest moon of Jupiter, the eponymous Callisto. Things turn from bad to worse when other prisoners start changing into monsters. Jacob has to face those horrors and unveil the dark secrets of Callisto.

Survival horror

It's a perfect game for every player who appreciates an exciting story and a tense atmosphere that keeps you on the edge of your seat. In the hostile world of Callisto, every enemy encounter may be your last. Consequently, Jacob has to use everything he can to survive. The Callisto Protocol combines range and hand-to-hand combat. You'll find quite unusual weapons, such as a gravity gun. It's going to be brutal, so prepare yourself for the sight of severed limbs and shot-off legs.
