20 Scariest Video Games Of All-Time

10. Outlast

Outlast isn't the best reviewed game on this list - indeed, it was met with mostly warm but not fantastic critical appraisal upon release. Still, as an exercise in terror, it's - quite frankly - horrifying in all the ways that a true horror game should be. And then some.

Partly inspired by the visual aesthetics in the film Jacob's Ladder, then (check it out if you haven't seen it - traumatising), Outlast has you as Miles Upshur, a freelance journalist who wants to investigate a mental asylum, and has only the ability to video stuff and run away. Did we mention that the environment the game is set in is immersed mostly in darkness, and that you have to view everything through a night vision camera?

And that said camera often runs out of batteries, because the people who designed this game really, really wanted you to suffer? And then there's the fact that Outlast is packed to the brim with all those little "tricks" that horror games so lovingly like to employ: lights shutting off at random, unseen things running around in the darkness. And that's just the beginning.
