Players attempting to check out the open beta for MARVEL Tōkon: Fighting Souls on SteamOS and Linux have run into a major roadblock. s the game currently blocks Linux systems from running the title due to anti-cheat incompatibilities.
Quick Facts
- Game: MARVEL Tōkon: Fighting Souls
- Developers: Arc System Works, PlayStation Publishing LLC
- Platforms: PC (Proton / Wine), PlayStation 5
- Release Date: August 6, 2026 (Standard edition priced at £59.99)

Easy Anti-Cheat Blocks Steam Machine and Steam Deck Access
During the open beta test, players attempting to load MARVEL Tōkon: Fighting Souls on Linux hardware—such as a Steam Machine or Steam Deck via Proton—are greeted with errors indicating that Linux support has not been enabled for the software's security layer. Arc System Works and PlayStation Publishing appear to be utilizing Epic Games' Easy Anti-Cheat, a system that requires explicit developer opt-in for Proton and Linux compatibility.
Notably, the presence of Easy Anti-Cheat was not disclosed on the game's official Steam store page before the beta rollout, leaving Linux-based players unaware of the restriction until attempting to boot the software.
Player Impact and How to Help
With Linux support absent, the fighting game is currently listed as broken on dedicated compatibility trackers. For players hoping to see the restriction lifted before the official launch, community members have pointed to active discussion threads on the Steam community forums where feedback regarding Linux and Steam Deck support is being gathered.
MARVEL Tōkon: Fighting Souls is scheduled to officially launch on August 6, 2026, with a standard edition price tag of £59.99. Whether Arc System Works and PlayStation Publishing will enable Easy Anti-Cheat's Proton compatibility before or after release remains unconfirmed.
