Background is a set of events invented for a plot, presented as preceding and leading up to that plot. It is a literary device of a narrative history all chronologically earlier than the narrative of primary interest. In my project it's a single player strategic horror game emphasizing logical thinking and planning. They often stress resource and time management, which usually takes precedence over fast action and character involvement. Tactical organization and execution are necessary, and the game creators usually place the decision-making skills and delivery of commands in the player's hands. The story behind the game is so horrible and tragic. The game is based on a true story. The story is about on a suicide of 406/B, M. K. Ali Hall, PSTU.
