Alien: Isolation is one of the best survival horror games of the last 10 years. We gave the game an 8.5/10 in our review and said: Alien: Isolation is close to a survival horror masterpiece that, while unforgiving, carries itself with an unbridled sense of style and class. It authentically recreates the look and feel of the original 1979 film while still feeling incredibly rewarding. Through some wizardry, the game plays just as well, if not better, on Switch, and is to be commended as one of the best ports the platform has ever seen.
