Marathon Update 1.1.5.4 is live with Ordnance Heist, a multi-run PvPvE event that sends Runners across several zones in pursuit of UESC targets, Locker keys, and the Firestorm. Bungie’s official update notes confirm that the event will remain available through September 1.

Successful extractions with UESC Manifests will help players gear up through the updated MIDA and Traxus Armories. The chase is built around repeated runs, so getting the loot out safely remains just as important as finding it in the first place.

Outside Ordnance Heist, Ranked maps now offer more loot and a better chance of producing blue and purple gear. The update also fixes several inventory problems, including lost items after Rook or Sponsored Kit runs when a player’s Vault was full.

Combat changes temporarily reduce the power of certain V85 Circuit Breaker mod combinations, targeting unintended one-hit knockdown body shots. Bungie also corrected an Outland rate-of-fire issue, Crew Fill behavior, contract problems, and a compass display error in Italian.
