About Marathon
Developed and published by Bungie and released on March 5, 2026, Marathon is the studio's long-awaited return to the franchise that started their legacy in the 1990s, completely reimagined as a team-based PvPvE extraction shooter. Set on the ruins of the colony world Tau Ceti IV, players choose from a roster of cybernetic mercenaries called Runners, each with distinct abilities, and drop into missions with a squad of three to scavenge weapons, implants, and gear from rival teams and AI-controlled security forces.
The extraction loop is the heart of the game — survive the match and keep your loot, or die and lose everything you brought in. Every run is a calculated risk, and the tension of deciding when to push deeper into the map and when to extract with what you have is what separates experienced players from newcomers. Five unique maps range from accessible beginner zones to high-stakes ranked play, each with different threat profiles and extraction points that reward map knowledge and squad coordination.
Customisation runs deep — over time players build and refine their Runner through looted weapons, implants, and gear that carry across sessions, creating a persistent progression layer within the extraction framework. Bungie's two decades of first-person shooter expertise are evident in the gunplay, which is precise, responsive, and immediately distinguishable from every competitor in the extraction shooter genre. Marathon launched to a Very Positive rating on Steam with 89% positive reviews and a Metacritic score of 81, with critics highlighting its bold visual direction and deeply satisfying core gunplay as standout qualities.

Marathon is designed around squads of three players. While you can queue solo and be matched with other players, the game is fundamentally built around coordinated team play. Going in without communication puts you at a significant disadvantage against organised squads. If you plan to play regularly, having at least one or two regular teammates is strongly recommended.
Marathon is a paid game priced at $40 at launch. It is not free to play. Once purchased, all core game content is included with no mandatory additional purchases required to play. Cosmetic items and additional content may be available separately through seasonal battle passes.
No, Marathon is not currently available as an included title on Xbox Game Pass. Purchasing a key is required to access the game.

On PC via Steam, no subscription beyond the game itself is required.
