BULKHEAD acknowledges that a community-manager message was incorrect and circulated as a Discord screenshot. The September 4 clarification supersedes that message: the studio says successful earlier alpha or beta sessions did not establish official Linux support.

That distinction matters if you played an earlier build. A working session then is evidence about that build and setup, not a promise that the September client or Early Access release will work.

The developer specifically tells players who bought the game expecting Linux via Proton at launch that they can seek a refund. It hopes to confirm compatibility later, without committing to a date. Read that statement before planning to play on a Linux desktop or a Steam Deck running SteamOS. EVIDENCE / 01BULKHEAD: Linux compatibility update, September 4Open source (opens in a new tab)

The published system requirements remain Windows-based. If you can use a Windows PC, compare it with the PC requirements; changing the operating system alone does not establish that the hardware is sufficient. EVIDENCE / 02WARDOGS on SteamOpen source (opens in a new tab)
