About Marathon

Built on over two decades of first-person shooter expertise, Marathon is Bungie's return to the franchise that launched their legacy, now reimagined as a squad-based PvPvE extraction shooter set on the ruined colony world of Tau Ceti IV. Players select from a roster of cybernetic mercenaries called Runners, drop into hostile territory with a squad of three, and fight through rival teams and AI security forces to extract weapons, implants, and gear.

The risk and reward loop is central to everything — survive and keep your loot, or die and lose it all. Each Runner brings unique abilities that complement different squad compositions, encouraging players to experiment with builds and strategies across multiple maps ranging from accessible beginner zones to high-stakes ranked play. Marathon launched to a Very Positive rating on Steam with 89% positive reviews and a Metacritic score of 81.
