A hard-as-nails but still quite a satisfying experience.
Void of any puzzles or exploration features, The 3rd Birthday is a dedicated shooter game that focuses on making life difficult for the player. But there are loads of great-looking cinematics as well as in-game vids with a twisted story that revolves around a screwed timeline. Talking about twisted, the monsters are called Twisted, and they look the part, which makes killing them an unsightly and morbid experience. For fans, no mention of mitochondria here.
Of course, the best parts of the game is Aya Brea herself, with costume unlockables and the infamous shower scene, which requires a perverted amount of dedication to unlock. Unless the main protagonist is your motivation to play the game, or you're a glutton for punishment, look elsewhere perhaps.
