Cigarettes buy information. Information opens doors.
The free PROCEDURE ZERO demo is now available on Steam: the first two missions, about 25 minutes of play.
PROCEDURE ZERO blends first-person stealth with psychological horror. Your name is not in the register — and someone who officially does not exist is still knocking. Trade cigarettes for information, learn patrol routines and use the radio to draw a guard's attention away. You never kill anyone.
The demo has text in 23 languages and full audio in English, Simplified Chinese, Japanese, Polish, Brazilian Portuguese and Russian. PROCEDURE ZERO is made by one developer in Poland and takes part in Steam Next Fest from October 19 to 26, 2026.
