Bungie’s Walled Garden: Why "Marathon" is a Hard Pass for Steam Deck and Linux Gamers

The Bottom Line: Bungie has confirmed a March 5th release date for their extraction shooter, Marathon. However, despite the game sitting at the top of Steam’s best-seller charts, we expect it to be dead on arrival for anyone using SteamOS or Linux. Bungie continues to refuse to toggle the "on" switch for BattlEye’s Proton support, effectively locking out the Steam Deck community and sabotaging Valve’s upcoming Steam Machine hardware push.

We’ve seen this movie before. For years, the Linux community has begged Bungie to allow Destiny 2 to run on Proton. Instead of a "QoL" update or even a neutral stance, Bungie responded with open hostility, famously threatening permanent bans for anyone attempting to bypass their blocks to play on Linux. With Marathon, the studio is doubling down on that same anti-user philosophy.

The Technical Breakdown

The irony here is that the technical hurdle is virtually non-existent. Marathon utilizes BattlEye, an anti-cheat provider that has offered a "check-box" solution for Linux compatibility for years. While other major studios have enabled this to support the Steam Deck, Bungie chooses to remain in their walled garden.

A Studio in Flux

Our analysis suggests this isn't just a technical decision; it’s a symptom of the "new" Bungie. The veteran talent from the Halo glory days is long gone, replaced by a corporate structure that seems more interested in pre-order metrics than community goodwill. After the disastrous launch of Concord from former Bungie staff at Firewalk, the pressure on Marathon to be an instant hit is massive. Yet, they are willingly alienating a rapidly growing segment of the PC market.

Pre-ordering a live-service title in 2026 is already a gamble. When you add Bungie’s track record of mass layoffs and their weirdly aggressive stance against Linux, that gamble looks even worse. If you’re looking for a competitive fix, we suggest sticking with titles like ARC Raiders, which actually respect your choice of operating system.

Key Takeaways for Gamers

• Release Date: March 5th, 2026.
• Steam Deck/Linux: Expect zero support at launch. Bungie has ignored multiple press inquiries regarding this.
• The Pre-order Trap: While the game is a top-seller, the "2-week/2-hour" refund window still applies, but we recommend waiting for day-one performance reviews.
• The Anti-Cheat Wall: BattlEye is capable of running on Linux, but Bungie specifically chooses not to enable it.

We believe this is a missed opportunity for Bungie. By ignoring the Steam Deck, they are ceding ground to more flexible extraction shooters. In an era where live-service games live or die by their player count, locking out an entire ecosystem feels less like a security choice and more like a slow-motion car crash.
