Marathon Update 1.1.5.4 Launches Ordnance Heist and Nerfs V85 Circuit Breaker
Marathon Update 1.1.5.4 introduces the Ordnance Heist event running through September 1st, alongside ranked loot table buffs and targeted damage nerfs for the V85 Circuit Breaker weapon.
Marathon Update 1.1.5.4 brings a new multi-run chase mode, adjustments to high-end weapon damage, and several quality-of-life fixes for ranked and solo queues. The update also lays the groundwork for updated MIDA and Traxus Armories access.
Ordnance Heist Event and Ranked Loot Buffs
The Ordnance Heist PvPvE experience runs until September 1st. Players hunt for the Firestorm across multiple zones, acquire Locker keys, and extract with UESC Manifests to gear up in the MIDA and Traxus Armories. Ranked maps now yield higher volumes of better loot, increasing encounters with blue and purple gear. Sekiguchi implant stock levels now match other factions.
V85 Circuit Breaker Combat Adjustments
The V85 Circuit Breaker receives direct nerfs to curb unintended power spikes. The Overclocked Delimiter Prestige Mod effectiveness drops when paired with the weapon. Last Resort and Reckless Behavior mod damage bonuses also decrease when equipped with the V85. These temporary adjustments remove unintended one-hit knockdown body shots.
UI, Fixes, and Quality of Life
A bug defaulting players to Crew Fill off when returning to Trios after Solo or Rook runs is fixed. Warped items are re-enabled, and a vault inventory loss issue following Rook or Sponsored Kit runs is resolved. Mismatched names and objectives on CyberAcme contracts, unclaimed Cryo Archive contracts, and an Italian compass display issue are patched.
Why this patch matters
Update 1.1.5.4 addresses immediate balance outliers on the V85 Circuit Breaker while injecting fresh engagement into the game through the limited-time Ordnance Heist event.
