What is The Callisto Protocol?
The Callisto Protocol is a narrative-driven, third-person survival horror game set 300 years in the future. Players will take on the role of Jacob Lee, who finds himself imprisoned in Black Iron Prison on Jupiter's moon, Callisto. When inmates begin to transform into monstrous creatures, chaos erupts within the prison walls.
To survive, Jacob must fight his way to safety and escape Black Iron Prison while uncovering the dark secrets hidden beneath the surface of Callisto. The game features both shooting and close-quarters combat mechanics, requiring players to adapt their tactics against rapidly evolving creatures. Players can scavenge for new weapons, gear, and abilities to help them outrun the growing threat and escape the horrors of Jupiter's Dead Moon.
The Callisto Protocol was developed by Striking Distance Studios and published by KRAFTON, Inc. It was released on December 1, 2022. The game is available for single-player experiences and supports controller input. Players can expect to spend approximately 10 hours completing the main story, 12 hours if they include additional content, and 16 hours for a completionist playthrough.

The Callisto Protocol is a satisfyingly gory spiritual successor to the Dead Space series, but it’s ultimately more of a striking modern mimic than a scary new mutation.

Gory and moody, The Callisto Protocol doesn't mess with the survival horror formula, instead embracing all its beats and clichés to tell a grim sci-fi tale that drips with menace.

Dead Space comparisons are impossible to avoid - but while The Callisto Protocol's missing some of the depth and tension, it makes up for it with production value and bloody-minded fun.

If you wanted anything more out of this second crack at making a new sci-fi IP in survival horror, or something markedly different that acknowledges just how far gaming has come since 2008, The Callisto Protocol is not your answer.

5 / 10
Though it starts off on a strong note, The Callisto Protocol's focus on action-heavy spectacles fails to adequately explore its horror and overcrowds its weak combat mechanics.
