Procedure Zero

Procedure Zero is a first-person stealth game about an auditor imprisoned after copying information he was never meant to see. His prison file contains no name or sentence, only the word ZERO. In the block, lights sometimes go out; when they return, one prisoner has vanished, and you are next.

Stealth and missions

You watch the guards, learn their routes and wait for a chance to act. You can create distractions, such as turning on a radio or setting a cardboard box on fire. When a guard investigates, you can knock him out with a baton, drag him by the legs into an empty room and lock him inside. Not every mission can be completed quietly: some involve beating someone up, and prisoners in whose cells you enter will attack you with their fists. You can also start a fight with any prisoner. Documents you find along the way reveal what is happening in the prison.

Prison alliances

Cigarettes and coins are the prison's currency. You use them to buy information, favors and help from other prisoners. Almost everyone wants something from you, and keeping your side of a deal can earn you an ally.

Take over the prison

With each mission, you take control of another part of the prison. The map shows which areas are yours. You gradually gather people to help uncover who is behind the disappearances and find a way out.
