Shadow Arena

On Linux, Steam Deck and Steam Machine

Its anti-cheat (nProtect GameGuard, XIGNCODE3, Easy Anti-Cheat) is not working on Linux for this game, so it won't run properly even where Proton otherwise could handle it. nProtect GameGuard runs on Linux in 14 other games Sifter tracks; XIGNCODE3 runs on Linux in 15 other games Sifter tracks; Easy Anti-Cheat runs on Linux in 144 other games Sifter tracks — so this is a per-game decision rather than a limit of the anti-cheat.

Valve rates it Unsupported on Steam Machine. Valve marks it Unsupported on SteamOS.
