Marathon Update 1.0.9 Patch Notes (May 2026)

The biggest thing in Marathon's 1.0.9 update is Warden Hunt, a new limited-time mode running until the end of Season 1. Wardens now spawn at new POIs across Perimeter, Dire Marsh, and Outpost, they're guaranteed to drop locked room keys, and every run has a guaranteed zone event. Combined with +50% Runner and Faction XP, this is a solid push to get players back into the maps before the season wipes everything on June 2.

On the balance side, the Impact Shockwave mod on the Ares Railgun has been reined in hard, it no longer one-shots players with blue shields or higher, and its explosive damage against players has been cut by 75%. That was a problem that needed fixing, and I'm glad Bungie moved on it. Rook also gets a temporary buff package until Season 2: Deluxe Patch Kits, Shield Charges, Deluxe Shield Implants, and an extended Signal Mask duration while sprinting. Whether that's enough to make Rook feel competitive is a fair question, but it's a clear acknowledgement that the class needed help.

There's also a wave of bug fixes covering reputation gains, contract objective ordering, zone audio, and a Thief exploit that let players bypass UESC barriers in Cryo Archive. Everything in the update is listed below.
