Scott Cawthon's indie horror game Five Nights at Freddy's (also available for Android) should probably be called "Half a Shift at Freddy's Before You Quit by Leaving a Scrawled Middle Finger for Your Supervisor to Find the Next Morning". The gist is that you take a job as an overnight security guard at Freddy Fazbear's Pizza, where all you should have to do is sit around and watch the monitors, though what you actually end up doing is finding yourself being stalked by animatronic horrors who creep through the dark hallways to where you cower in your office, nice and fresh for dismemberment. Your defense? Well, all you can do, all you can literally do, is play with the light switches and close the two doors on either side of you. Temporarily. See, you have a limited supply of power to last you through the night, and keeping the electronic doors closed or the lights on will burn through it much, much faster, leaving you defenseless when it runs out. As a result, you have to watch your monitors, tracking the movements of the unpredictable fur-and-steel murderers, and figure out when it's safe to leave yourself exposed. So, yes, Five Nights at Freddy's is basically proof that the internet has a deep, abiding love affair with jump scares, self-loathing, and trying to make you void your bowels.
