Outlast

One of the most terrifying games of recent memory, Outlast was made available for free for PS Plus customers on the PS4 earlier this year. Set in a home for the criminally insane, its plot revolves around an intrepid reporter who follows up on a tip that human experiments are being conducted on inmates. After breaking into the asylum, things naturally go sideways. With enough jack-in-the-box scares, nail-biting sequences and disturbing subtexts to make Wes Craven flinch, Outlast is a must for survival horror fans.
