Dead Mans Diary — is a tense first-person survival horror game set in a post-apocalyptic setting. Fifteen years have passed since the start of the nuclear war, which led to a global catastrophe. Nuclear fallout completely destroyed humanity. Those few who managed to survive are hiding in underground bunkers. However, supplies are running out, and periodically some people are banished to the surface so that the rest can survive. This is how the protagonist finds himself in a dead, hostile world, with no idea what to do and how to stay alive.
