What anti-cheat does WARDOGS use?

Both August tests ran Easy Anti-Cheat. The install folder had an EasyAntiCheat directory, the launcher's failure dialog read "Anti-Cheat Login Failed", and the fixes on the EAC page were written against that build. The Steam listing said the same until at least 7 September. It now reads "Uses Kernel Level Anti-Cheat", provider Elytra.

The Closed Beta 02 build did something else. From 2 September players opening the Playtest folder found Elytra\Elytra-Setup.exe where the EAC installer used to be; the launcher's failures named Elytra.Service and "Elytra Anti-Cheat Framework Setup Failed"; and the moderators in the official Discord titled their fix thread for Elytra, not EAC. None of that was an announcement, and Bulkhead has still not explained the switch. The store page has since settled it by naming Elytra.

Elytra itself is not obscure. It is the anti-cheat VAIIYA built for Embark Studios, rolled into THE FINALS in August 2026 with ARC Raiders expected to follow. Its appearance in a Team17-published game from a different studio is the surprising part, and it is the part nobody official has addressed.

"Kernel-level" means the anti-cheat installs a driver that runs at the deepest layer of Windows — underneath the game, and underneath any program you could open yourself. That is what lets it catch cheats a normal program cannot see. It is also why it only works on the operating system it was built for, and both of these were built for Windows.

Proton is the tool that lets Linux and the Steam Deck run Windows games. It can run the game, but a Windows driver has nowhere to go inside it. So the anti-cheat company has to make a separate Linux version, and the game studio has to switch it on. Easy Anti-Cheat has one — that is what Bulkhead's August line, "we are working on proton support", was about. Whether Elytra has one Bulkhead can switch on is exactly what the September build answered, and the answer was no, at least for that build: the anti-cheat downloads fine, then fails to install inside Proton, and a player who somehow gets past that point is kicked after about a minute because the driver never checks in.

Both of those messages, and why nothing on your end fixes them, are on the Linux error page. The full story, from the beta that ran on Linux to Bulkhead's 25 September update, is in does WARDOGS work on Linux or Steam Deck? That is the link between the "kernel level" notice on the store page and the pinned Linux thread: they are the same fact, seen from two ends.

On 4 September a Bulkhead developer pinned a thread to the Steam forum titled "UPDATE: Linux Compatibility". It has run past five hundred replies since. The statement, in full:

We do not officially support Linux and we cannot commit to having support for launch. We are still working on Official Linux Proton compatibility.

This official stance has not changed since pre-release. We admit there was a mistake in communication by our CM which was unfortunetly screenshotted in our Discord and then posted on the linux Reddit, when the official stance has always been 'we are working on proton compatibility'.

Any previous Alpha/Beta test where Linux worked was by happen stance, which led to some users discuss the game as being Linux compatible. However, as previously stated - we do not yet officially support Linux and we are still working on our proton support for WARDOGS. We will update our stance once we have this confirmed. That is our goal.

We cannot commit to having Linux support for our Early Access launch. So please, refund the game if you mistakenly bought it thinking you would be able to run Linux via Proton on September 10th. We hope to have you back as soon as we can confirm official compatibility.

We know this is not what you want to hear... but the continued demand for Linux has been heard and it is still in our sights. Thankyou.

Three things in it are worth separating. The position — no official support, Proton being worked on — is the same one a developer gave on the same forum in August, and it is Confirmed. The refund instruction is unusual for a studio six days from launch and it is the most useful sentence on this page for a Linux player. And the "happen stance" line is the official explanation of why the August betas ran on Linux at all: Easy Anti-Cheat's Linux version happened to be switched on, nobody had promised it would stay that way, and the September build proved the point.

What the statement does not do is name an anti-cheat. It neither confirms Elytra nor explains why a build that ran on EAC in August stopped working on Proton in September. The players in the thread make that connection; Bulkhead's post does not.

NVIDIA announced it and then could not ship it. The GFN Thursday post on 10 September said WARDOGS launches on GeForce NOW today, bringing BULKHEAD's large-scale tactical first-person shooter to the cloud at early-access launch. It did not arrive, and NVIDIA said afterwards that a last-minute conflict with the game's anti-cheat was why, adding that it is working with the publisher and will say more when there is a fix. No date has been given.

The mechanism is the one the rest of this page describes from a different angle. A cloud session is a virtual machine, a kernel-level anti-cheat is built to be suspicious of exactly that, and the environment has to be allowed explicitly from the publisher's side — which is why this is not something NVIDIA can switch on alone. Players who tried it on launch day report the anti-cheat refusing the session rather than the game failing to load.

Treat any "play WARDOGS on GeForce NOW" listing dated before 11 September as the announcement rather than the outcome. This section changes when NVIDIA or Bulkhead says it has.

There is no Deck-specific answer because there is no Deck-specific statement. Steam shows no compatibility rating for WARDOGS, Bulkhead has never mentioned the Deck, and a Deck runs the game the same way a Linux PC does — through Proton, against the same anti-cheat, stopping at the same step. Everything in the section above applies. The one extra thing to know is that the game is not listed as controller-supported on Steam either, so even a working Proton build would be a keyboard-and-mouse game on a handheld; the controller page has what partial gamepad support actually covers.

This page explains; the error pages fix. Which one you want depends on the word on screen.

• It says Elytra — "Elytra Launcher Service start failed", "Elytra Anti-Cheat Framework Setup Failed", or "Session prime failed: RPC error": the Elytra page.
• It says Easy Anti-Cheat — "Anti-Cheat Login Failed", or EAC refusing to install: the EAC page.
• It says the anti-cheat refused the game executable: that page, which is a Windows security-policy fault rather than either anti-cheat.
• You are on Linux or a Deck — "an anti-cheat module could not be downloaded or installed", or kicked for no heartbeat: the Linux page, which has no fix and says why.
