G4TV writes: "Cryostasis: Sleep of Reason is an especially appealing game for fans of horror who want something distinctive. It's a slow, brooding, atmospheric journey into interactive story telling and very different from other recent games in the spooky genre. Other player may be turned off from the repetition of both foe and corridor. In a larger sense, it all makes sense and adds to both the story and atmosphere of the game – the claustrophobic steel hallways, the desolate white wasteland awaiting outside, and the fear that every fight may be your last. If you don't mind the frozen nature of the gameplay, this is a ghost story well worth experiencing". 4/5
