Marathon 1.1.5: a PvE roguelite mode is arriving on this date
In brief
Marathon 1.1.5 arrives on July 21 with Vault Breaker, an experimental PvE roguelite mode long awaited by the community. Bungie is positioning it as a testing ground ahead of the full PvE mode planned for Season 3 (September), but be warned: rewards only partially extract.
The midseason 1.1.5 update for Marathon arrives on July 21, and it brings what the community has been asking for since launch: a mode with no PvP. Not yet the full mode - but something concrete.
Vault Breaker: the experimental PvE
The mode is called Vault Breaker and takes place in Cryo Archive. Roguelite structure: you chain Vaults with increasing difficulty across multiple runs. What matters for the average player is the total absence of human opposition - no more PvP stress for those who just want to explore Marathon's gunplay without running into an ambushing squad, or simply for those who want to train at their own pace!
The core mechanic revolves around Vault Data, a run currency used to upgrade your Sponsored Kit or buy equipment in a dedicated Armory. Beware though: items found during a run do not get extracted. Only Vault Data and event rewards come out with you. Farming therefore remains limited to the duration of the event.

Full PvE: see you in Season 3
Bungie is clear: Vault Breaker is a testing ground. The feedback and data collected will feed into the full PvE mode planned for Season 3, in September. That mode, unlike the current event, should be built to last - but details are still to come.
Reception: hope tinged with impatience
With no community feedback available at the time of writing, caution is warranted. The limited extraction constraint risks being divisive: players who wanted a PvE mode to bring loot back into their regular sessions will be disappointed. Those just looking for a chill mode to learn the mechanics should find what they need.
