WARDOGS does not run on Linux or Steam Deck. Steam lists Windows as the only supported platform, and the kernel-level Elytra anti-cheat that shipped with Early Access has no Linux or Proton path.
BULKHEAD stated the position plainly before launch. In an official Steam post on 4 September 2026, developer KingHoward wrote: "We do not officially support Linux and we cannot commit to having support for launch," and told players who had bought the game expecting Proton support on 10 September to refund it.
Why it worked during the beta and stopped at launch
The closed beta builds used Easy Anti-Cheat, which has a Proton compatibility path that a developer can enable. That is why Linux players and Steam Deck owners were able to play during the test period.
BULKHEAD has characterised that as happenstance rather than as supported behaviour. The anti-cheat changed to Elytra for the Early Access build, and a kernel driver written for Windows has no equivalent Proton route.
This is the part that generated the most frustration, and it is worth being precise about: the capability was real during the beta, but it was never an announced feature, and the developer statement of record has been consistent that Linux was unsupported.
The refund BULKHEAD offered
The 4 September post is unusually direct: "Please, refund the game if you mistakenly bought it thinking you would be able to run Linux via Proton on September 10th."
That was published before Early Access opened, which matters for Steam’s refund window. If you bought on the strength of beta-era Linux compatibility, this is the developer telling you to take the refund rather than wait.
Standard Steam refund rules still apply to the request itself; the developer post is a statement of intent, not a separate refund mechanism.
Launch options and workarounds
Players have found launch parameters that get the client to start under Proton, far enough to reach the firing range. It does not get you into a match: the anti-cheat removes you from official servers.
BULKHEAD has advised against this route and indicated it carries a ban risk. Given that incorrect bans were already an acknowledged problem at launch, deliberately presenting an unsupported environment to a kernel anti-cheat is a poor trade.
There is no configuration, Proton version or compatibility layer that resolves this. The blocker is a Windows-only kernel driver, not a missing library.
Do not use launch-parameter workarounds to get onto official servers. The developer has warned they may result in a ban, and no workaround makes the anti-cheat itself run.
What BULKHEAD has not published
There is no date for Linux or Proton support. The team says it is "still working on Official Linux Proton compatibility" and will update its stance "once we have this confirmed", which is a goal rather than a commitment.
No Steam Deck verification status has been announced either, and none could be while the anti-cheat is Windows-only.
Whether Elytra itself will ever gain a Proton path is not something BULKHEAD has addressed, and it is not entirely in their hands.
Linux and Steam Deck questions answered
Short answers to the most common questions.
- Does WARDOGS work on Steam Deck? — No. Steam lists Windows as the only supported platform and the anti-cheat is Windows-only.
- Does WARDOGS work on Linux via Proton? — No. Elytra has no Proton path, so you are removed from official servers.
- Why did it work in the beta? — The beta ran Easy Anti-Cheat, which has a Proton path. BULKHEAD describes that compatibility as happenstance.
- Can I get a refund? — BULKHEAD explicitly told players who bought expecting Proton support to refund. Standard Steam refund rules apply to the request.
- Is there a launch option that fixes it? — No. Some parameters start the client, but the anti-cheat still removes you from official servers, and the developer warns of a ban risk.
- Is Linux support coming? — No date. The team says it is still working on Proton compatibility and will update its stance once confirmed.
