On Linux, Steam Deck and Steam Machine

Its anti-cheat (Nexon Game Security) is not working on Linux for this game, so it won't run properly even where Proton otherwise could handle it. Nexon Game Security runs on Linux in 10 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.
