I would like to kindly ask Fatshark to allow the EAC in WARHAMMER: Vermintide 2 to support Valve’s Steam Deck and Linux.
I have personally tried to run the game on Linux, and it does run perfectly well… But only on the modded realms, as the Easy Anti-Cheat (EAC) prevents the game from running on the official realms, because EAC “did not” support Linux back then.
Fortunately, Epic Games have recently announced that Easy Anti-Cheat now has full support for Linux and the Steam Deck. Game developers must opt-in to enable EAC to support Linux (which’s why I’m asking here). The icing on the cake is that the process of opting-in seems to be very simple (“just a few clicks” according to Epic Games).
Since Vermintide 2 already runs great on Linux (on the modded realms anyway), I believe that opting-in to support the OS through EAC could only be seen as a net-positive. First, the process of adding support to the Steam Deck and Linux through EAC should be very simple. Secondly, official support for the Steam Deck and Linux is not required to let the game run on those platforms (any encountered issues will go to proton developers instead). And finally, this will open the game to a new market as the hype for the Steam Deck is surprisingly high (Valve anticipates that they will sell millions of these). Given all the above, I believe that allowing EAC to support the Steam Deck and Linux seems to be a great idea.
Obviously, I am no game developer, and I realize that this may not be as simple as “just a few clicks”. If unfortunately, it turned out to be more complicated, I would like to know why it cannot be implemented. And to make it clear yet again, I am not asking for official support for Linux, but just to allow EAC to support it. This change alone will let the game run perfectly well on Linux. In turn, I and many others could not be more satisfied (although a definitive release date for Darktide would be very much appreciated).
