Michael Huber: "The Callisto Protocol is a solid first entry in what Striking Distance hopes to be the next big horror franchise. Flawed, but unique and engaging melee combat is a fun way to fight against terrifying foes, while Black Iron Prison is an alluring space to investigate. Limited exploration, a cliché story, and forgettable firearms hold it back from being truly great. However, underneath the blemishes, The Callisto Protocol pushes horrifying visual detail to emphasize tense and perilous encounters."
