Zatun's psychological survival horror game reaches Steam Early Access for Windows PC on 25 October 2026. Chapter I will be playable at launch, and a demo is available now.
At Site-19, a containment failure has left researcher Alexie facing escaped anomalies and dwindling supplies. Zatun says SCP: Project Pneuma will enter Steam Early Access for Windows PC on 25 October 2026, with the full Chapter I campaign included.
PocketGamer.biz profiles Zatun as a developer of PC games. The studio also makes games for iPad. Its work extends to iPhone and Android. Game Informer has linked the developers of Pneuma: Breath of Life with The Turing Test, a first-person puzzle game about the philosophy of human consciousness.
The opening chapter moves through abandoned sectors and research facilities. Players will also reach forest areas and checkpoints around the ruined site. They take the role of Dr Alexander "Alexie" Kolchak, one of the few survivors, and investigate the disaster while trying to stay alive.
Zatun describes a single-player game built around exploration and stealth. Investigation and environmental puzzles also drive the campaign. Direct combat is not presented as a reliable way out: supplies are limited, and survival depends on learning how each anomaly behaves. Players uncover the containment failure through journals and voice recordings. Environmental evidence and abandoned equipment fill in more of the story.
The announcement names SCP-173Z as one of the threats. SCP-096Z is also listed. Zatun names SCP-939Z, then SCP-239Z. The announcement does not describe their individual mechanics, so their behaviour cannot yet be assessed from the information provided.
The horror also comes from changes to the environment. Hallucinations can distort familiar spaces, and routes may shift without warning. As Alexie's mental state deteriorates, the line between the facility and his perceptions begins to blur.
That makes perception part of the survival challenge. A passage that looks safe may not stay that way, while investigating the site helps players piece together its history. Zatun has supplied no independent gameplay testing or performance measurements. The announcement sets out the intended mechanics, but offers no evidence of how consistently they work in play.
Zatun says a sequel is in development. It is planned to add locations and gameplay features, with more narrative content and anomalous encounters. The studio has given no release date for it. During Early Access, Zatun says community feedback will guide work on performance and stability. It also plans to use that feedback to address balance and overall polish.
Zatun announced the Early Access date on 14 October 2026. The Windows PC release is set for 25 October, and a playable demo is already available on Steam. Chapter I's full story campaign is included. The announcement gives no price. It also provides no detailed technical specifications, and lists no further platform releases.
The short interval between announcement and launch gives players a chance to try the demo before release. NGB has also covered a longer Steam wishlist runway for Squadron 42. The games have separate schedules, with SCP: Project Pneuma set for Early Access in October. The demo and wishlist are available through the game's Steam page.
Early Access makes a game available before the developer considers its broader development work complete. It gives the studio a chance to gather feedback and revise the experience, but does not guarantee when later content will arrive or how much the game will change. For Project Pneuma, Chapter I is the confirmed playable scope at launch. The planned sequel and any future additions sit outside that package.
