Initially scheduled for release on September 23, 2025, the game Marathon was postponed by developers Bungie due to mixed reactions during Alpha testing and an uproar over alleged stolen art assets. The team is dedicating additional development time and will reveal a new launch date sometime this fall. Until then, monthly playtests of Marathon are being held, granting early access to selected players for testing new builds. The third Closed Playtest for Marathon, which occurred from September 5-7, has seen some details leaked, despite Bungie’s efforts to maintain secrecy.
