Steam Deck users face disappointment as Bungie’s upcoming extraction shooter, Marathon, skips native support on the handheld device at launch. PlayStation, Xbox, and PC players dive into the action on Tau Ceti IV starting March 5, 2026, while Valve’s portable remains sidelined.
Gameplay and Setting
Marathon revives the universe of the 1994 classic. Players control ‘Shells’—robotic bodies with uploaded human minds—tasked with exploring hostile zones, gathering loot, and extracting safely. This tense loop s games like ARC Raiders, but unfolds in a cosmic battlefield.
The BattlEye Barrier
Despite Marathon’s modest system requirements suggesting compatibility with Steam Deck, Bungie confirms the title integrates BattlEye anti-cheat software to safeguard servers from cheaters. While BattlEye technically accommodates Linux-based systems like SteamOS, developers frequently restrict access.
This setup s other BattlEye titles, including Destiny 2, Fortnite, Rainbow Six Siege, and Grand Theft Auto Online, all of which fail to launch on Steam Deck without modifications.
Workaround: Switch to Windows
Steam Deck owners can enable Marathon by replacing SteamOS with Windows 11. This adjustment permits BattlEye to function, unlocking the shooter alongside similar games.
However, drawbacks abound. Users note reduced performance from Windows’ background processes. Navigation proves cumbersome without optimized controller or touchscreen support, complicating handheld use.
Launch Timeline
A free server slam tests the waters from February 26 to March 2, 2026, ahead of the full release on March 5. Gamers must weigh the tweaks against remote play alternatives for portable access.
