Are you ready for the scariest game of them all? Convince yourself you are as you take on Outlast.

Stealth is key as players explore the asylum trying to uncover it's secrets, but this journalistic endeavor quickly turns terrifying as Miles gets hunted down by crazed human looking creatures and needs to escape the facility. Player's have no way to fight these creatures as Miles is equipped with just a camcorder that enables him see in the dark and will constantly need to flee from disturbing creatures and hide wherever is possible.

These unpredictable enemies can appear at any time and players need to be ready to run and try to shake them off at any instant. Player's never have a moment to mentally recover as horrors are literally everywhere in the game. Even more terrifying is that the game's setting and characters are inspired by actual asylums and instances of criminal insanity.
