Marathon Launches “Vault Breaker” Experimental PvE Mode

Bungie released Vault Breaker, a time-limited PvE experiment for *Marathon*, as part of Season 2’s mid-season update. The mode runs for two weeks and will close on August 4. It is confined to the Cryo Archive map and supports solo, duos or trios. Players cannot bring their regular loadouts; instead they start each run with a mode-specific Sponsored Kit that can be upgraded over successive attempts using Vault Data, a currency earned by looting and by killing a USEC Commander. All gear collected is converted to Vault Data on extraction, and only the currency can be spent in the Vault Breaker Armory for items usable outside the mode.

*Marathon* launched only four months ago and has faced mixed reception. Director Joe Ziegler departed the studio shortly after launch, and Bungie announced a round of layoffs. The experimental mode arrives amid these upheavals as the company seeks to broaden the game’s appeal beyond its core extraction audience.

Each run pits players against increasingly tough vaults and culminates with the Compiler, the standard Cryo-mode boss. While weapons and gear are looted, they cannot be extracted; only Vault Data is retained. The currency can upgrade future Sponsored Kits or purchase rotating store items usable in any mode, including the regular extraction experience. Killing a USEC Commander guarantees Tier One Vault Data, even if the team fails to extract.

Bungie indicated that Vault Breaker is a “half-measure” and explicitly labeled it experimental, noting that a more comprehensive PvE experience is slated for Season 3. The company has not announced a free-to-play trial for this mode, but analysts suggest a future free weekend could be used to test broader player interest.

Commentators view PvE as the “last card” for *Marathon* to attract less-intense players. Prior free-to-play periods did not substantially raise the player base, so expectations are tempered. The two-week window offers a limited data set for Bungie to assess whether a full PvE mode can meaningfully expand the game’s audience.
