ObsCure (PC/PS2/Xbox, 2004)
Perhaps no other game has ever been this aptly named. ObsCure was a title that hardly made a blip on the radar, but if one did happen to experience it, they would probably need a diaper change to get through the survivor horror game. The game focuses on a group of annoying high school seniors who uncover a secret laboratory where experiments are done on other students. Taking a page out of Alan Wake (or vice versa, considering its release date), you must use various flashlights to keep the infected army of students and guards at bay while escaping the facilities in order to warn the rest of your classmates. Yes, somehow there was a sequel to this, which was horrible, and a third in the series is in the works. Get. Excited.
