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.

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.
