Synthesized from 2 Yomimono stories · updated Oct 9

PROCEDURE ZERO was announced in September 2026 as a first-person survival horror game set in a prison. DELANIVO GAMES, the project of Polish independent creator Lukasz Twardowski, opened a Steam page for it. The player is an inmate with no name, no crime, and no record, tracked by surveillance cameras and treated as a normal prisoner. The game was scheduled for release within 2026 and supports Japanese display.

By October, the plan had a specific date. The game was confirmed for Steam on PC on Thursday, November 12, 2026. It is no longer described only as a 2026 release but as a dated one. The pricing was not stated. The premise remains a first-person stealth game set in a prison where cigarettes work as currency.

A free demo covers the first two missions, roughly 25 minutes of play. The demo was scheduled for Steam Next Fest, which runs from Monday, October 19 to Monday, October 26. The game supports Japanese voice audio alongside 23 text languages, a detail that places the project in front of a Japanese audience at the festival. Twardowski develops it alone under the DELANIVO GAMES name.
