Marathon 1.1.5.4 launches Ordnance Heist

Marathon 1.1.5.4 launches the Ordnance Heist PvPvE event, a multi-run chase across different zones that remains active through September 1. Players defeat UESC forces, acquire Locker keys and search for the Firestorm.

Marathon 1.1.5.4: confirmed details

Extracted UESC Manifests support purchases through updated MIDA and Traxus Armories. Ranked maps now contain more loot with a higher chance of blue and purple gear, and Warped items have been re-enabled.

What changes for players

A multi-run structure makes successful extraction feed the next attempt instead of ending at one isolated result. Better ranked loot raises the expected equipment floor, while temporary weapon-mod reductions remove unintended one-hit body knockdowns involving the V85 Circuit Breaker.

Timing and wider context

The patch also fixes inventory loss after a full-Vault Rook or Sponsored Kit run and several contract and interface problems. Ordnance Heist is limited-time content, so its September 1 end should be checked against the live client.

The feature list and timing above reflect the developer’s announcement published on August 18, 2026. Future hotfixes can adjust balance or availability, so live values should be checked against the current client.

For Marathon, the practical checkpoint is the live client: confirm the installed version, platform notes and regional rollout before relying on a scheduled feature. Store availability, maintenance windows and certification can create timing differences even when the developer announces one date for the wider release.
