Mid-Season 2 Update Preview: Vault Breaker PvE Mode Coming July 21
Bungie posted a preview blog on Steam detailing next week's mid-season update, which introduces Marathon's first experimental PvE mode called Vault Breaker. In it, runners use hit-and-run tactics to raid vaults inside the Cryo Archive for loot, alongside a batch of balance and progression changes. Full patch notes are expected when the update goes live on July 21.
