Old Evil — a new horror game that begins its plot a few years ago, it was the fall of 2018. A group of recruits from a private military organization underwent basic combat training in a forest near the Witch Hills. A few days before the end of training, the team stopped communicating. A search team was sent to the landing site. Cedric Still was in this group. It was he who saw the tracks going deep into the woods. A narrow, almost overgrown path Gray approached the peat bank of the swamp. There was an unpleasant, dizzying feeling.

The gameplay in Mask of Sanity is not that complicated, and everything happens here in the first person view. All you need to do is explore the premises of the hospital, look for clues, solve puzzles and guess riddles, and along the way hide from enemies that may attack you. But be careful and decide for yourself whether or not to fight your enemies. Perhaps it is better to run away from them. It’s up to you, even in Mask of Sanity you will find just an unimaginable atmosphere, horror. which are hard to imagine, a sea of ​​random events, and dark rooms with halls overflowing with something clearly sinister, and possibly otherworldly.
