EAC works on Linux, FatShark just didn’t initially choose that option, and about a year ago game became playable again. IIRC you should choose a beta workaround version in your steam client for that.

Yet, it’s fair to feel salty about that. Versus is a fine gimmick but wasn’t worth introducing EAC, like gatekeeping mods wasn’t too. It is too heavy-handed for a game with a small, tight-knit community, that would rather play a four Bardin game than install wallhack or aimbot for whatever reason.
