About Mortal Decay

Mortal Decay is a survival horror game set after World War III. You play as a starving survivor whose strength is fading as you enter an abandoned prison in search of food. The prison is not empty: unknown pursuers chase you, and you are too weak to fight, so you must escape.

The prison's past

As you search for a way out, you collect clues about why the prison was abandoned and the tragedies of the people who lived there. The pursuers’ motives are unknown, as is what they want with you.

Sneak and survive

You use stealth to avoid enemies across expansive, detailed environments. Multiple enemies have unique AI, and the game uses chilling sound design.
