You woke up in a psychiatric hospital. There was not a single living soul around. You wandered through the endless corridors of the hospital for half a day, until you came across strange mutilated creatures. Maybe it's just a dream. But I felt the monster's breath behind you, you quickly came to your senses and decided that you need to run. You managed to get a weapon and now you have something to protect yourself. Fight off these monsters and get out of this mental hospital.
