SCP: Project Pneuma is a single-player game, and its October 30, 2026, version 0.41 update made saves from earlier versions incompatible. Zatun’s Steam FAQ describes Chapter I as the current Early Access campaign, with Chapter II in development. The official information reviewed does not establish general save-slot or save-location details, or confirm mod and Steam Workshop support. Here is what is documented—and what players should check before starting or buying.
Release status and system requirements can change while the game is in Early Access, so use the current Steam listing and the latest update notes for the latest information.

What is the current state of SCP: Project Pneuma?
SCP: Project Pneuma is available in Steam Early Access, with Chapter I described as the playable campaign and Chapter II still in development. Steam lists its Early Access release date as October 25, 2026, and identifies Zatun as both developer and publisher. That means the available game is a work in progress, not a finished release with all planned chapters present.
Zatun describes Chapter I as a campaign involving explorable environments, investigation, environmental puzzles, and anomalous encounters. The developer says Chapter II is not included in the current version. Treat that as a statement about the version described in the Steam listing and developer FAQ; check the live page and newer announcements in case the contents have since changed.

Early Access matters when deciding whether to begin now. The current campaign may be playable, but the game and its content are still being developed. A planned chapter or estimated development schedule is not a delivery guarantee, and updates can change how a player’s existing installation behaves. The most concrete example for current players is the version 0.41 save warning discussed below.
Will my save work after an update?
Not across every update: version 0.41 specifically made saves from earlier versions incompatible and instructed players to start a new game. The version 0.41 notes are dated October 30, 2026, and are reproduced by SteamDB from Steam Community update notes.
Quick wins for a faster PC:
Scan for outdated or missing drivers - takes under a minuteDriver Scan →Clear out junk files and repair common Windows errorsFree Scan →If you have a save created before that update, do not assume it will load in version 0.41. The notes say that earlier-version saves cannot be loaded; the stated workaround is to start a new game. This is a specific migration warning for that update, not proof that all future updates will invalidate saves or that the same thing will happen on every patch. Read the version 0.41 notes for the original notice.
The available official material does not settle several broader save questions: how often the game saves, whether it offers multiple save slots, where save files are stored, or whether later versions preserve compatibility with saves made after 0.41. Avoid relying on an assumed save system or treating a particular folder or backup method as developer-confirmed. Before updating, check the notes for that specific version. If a note warns about incompatible saves, plan for a new game rather than expecting an old save to migrate.

For players deciding whether to start now, the practical choice is straightforward: start if you are comfortable with the possibility that an Early Access update could affect progress, and review each update’s notes before installing it. The 0.41 warning is evidence that a compatibility break has happened once; it does not establish the frequency or policy of future save changes.
Does SCP: Project Pneuma have multiplayer or co-op?
No multiplayer mode is listed: Steam identifies SCP: Project Pneuma as single-player, and Zatun’s launch announcement also calls it a single-player game. The reviewed sources do not list co-op or another multiplayer mode.
That makes the game a solo experience based on its published feature information. If you are looking for a game to play together, do not buy it expecting co-op on the strength of an unverified assumption. The listing can change as development continues, so check the current Steam feature information for any later announcement. Zatun’s launch announcement provides additional confirmation of the single-player framing.
Can you install mods or use Steam Workshop?
Mod and Workshop support are unconfirmed in the official sources reviewed. The Steam listing and Zatun’s launch announcement do not establish that the game supports mods, nor do they establish that modding is prohibited.

- What You Get: Anker USB-C Hub (7-in-1), welcome guide, 18-month warranty, and our friendly customer service.
That distinction matters: absence of a listed feature is not the same as a developer saying the feature will never exist. If mod support is essential to your purchase decision, check the latest Steam store features and developer announcements for a direct confirmation. Do not assume that a Workshop page, community-made files, or a particular installation method exists based on the game being available on Steam.
Likewise, the available information does not explain whether any future mod support would be official, whether Workshop would be the distribution method, or whether mods would remain compatible after game updates. Until Zatun or an official feature listing answers those questions, the reliable answer is simply that support has not been confirmed by the material cited here.
What does the Early Access version include?
The current version described by Zatun contains Chapter I; Chapter II is in development and is not included in that version. The developer describes Chapter I as a campaign built around exploration, investigation, environmental puzzles, and anomalous encounters.
Zatun’s Steam FAQ estimates that Chapter I takes most players “around 2+ hours.” That is a developer estimate, not a guaranteed playtime: an individual player’s pace and approach can differ. It is useful as a rough indication of the campaign’s stated scope, but not as a promise of a specific completion time.

The Early Access label also means the available chapter should not be confused with the whole planned game. The developer says Chapter II is in development, but the cited material does not make its future availability or timing certain. The announcement is a plan, not a release date. Players who want a complete multi-chapter story before buying should check the live listing for the latest content status and decide whether Chapter I alone meets their expectations.
Zatun’s developer FAQ gives an estimated Early Access period of approximately 6–12 months, while noting that the timeline may change. Treat this as an estimate rather than a firm launch window for a finished version or a commitment that Chapter II will arrive within that span. For the latest status, rely on current developer updates rather than carrying an older estimate forward as a fixed schedule.

Steam lists Windows 10 64-bit, 8 GB of RAM, 30 GB of available storage, and an SSD as minimum requirements. Its recommended requirements include Windows 11, 16 GB of RAM, and 30 GB of storage. The Steam listing also publishes processor and graphics requirements, but verify those exact entries on the live page before purchasing because requirements can change.
| Requirement level | Operating system | Memory | Storage |
|---|---|---|---|
| Minimum | Windows 10 x64 | 8 GB RAM | 30 GB available; SSD required |
| Recommended | Windows 11 | 16 GB RAM | 30 GB |
The table reflects the requirements described in the Steam system requirements; it is not a substitute for checking the live listing. In particular, the processor and graphics entries are also part of Steam’s published requirements, so compare those against your PC rather than relying only on operating system, RAM, and storage. The explicit SSD requirement is worth checking before installation: a drive with enough free space is not necessarily enough if it does not meet the listed storage type.

These are PC requirements for the Steam version described by the listing. The sources cited here do not establish requirements for other platforms. If you are close to a listed minimum, check the full current requirement details and any newer developer guidance rather than inferring compatibility from only the headline values.
What should you check before starting or buying?
Use this short checklist to match the game’s current state to what you want from it:
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitches- For a solo campaign: Steam lists the game as single-player. The reviewed sources do not list multiplayer or co-op.
- For a complete story: Chapter I is the current campaign described by the developer; Chapter II is planned and in development, not included in that version.
- For a saved run: version 0.41, dated October 30, 2026, broke compatibility with saves from earlier versions. Check every later update’s notes rather than assuming either safety or another break.
- For modding: official material reviewed does not confirm mods or Workshop support. Look for a direct current statement before making that a requirement.
- For PC compatibility: compare your hardware with the full live Steam requirements, including processor and graphics entries. The listing says an SSD is required at minimum.
- For timing: treat the stated Early Access duration as an estimate that may change, and use current announcements for new content or schedule details.
Steam’s listing and update notes are the key references because this is an Early Access game and both content and technical details may change. The dated version 0.41 save notice remains useful for understanding that particular update, but it cannot answer how a later patch will behave.
