Cryo, Uncontested.
Welcome to our Vault Beaker Megathread!
Due to the unprecedented nature of this activity being Marathon (2026)'s first PvE only activity, we felt it was prudent to establish a megathread where runners may discuss their feelings on this unique iteration of the game in a focused manner.
Share your thoughts! What's working, what isn't? What's weird and what's wonderful.
This Megathread will be swapped out with a fresh one next week once players are a bit more familiar with the state of the mode.
Shell Game
Vault Breaker Supports, Solo, Duo, and Trio playstyles. If you want to squad up with other runners to conquer the depths of the UESC Marathon
If you would like help finding fellow runners to plunge the depths of cryo with, feel free to check out our LFG Subreddit: r/MarathonTheGame, our LFG Megathreads: Tau-Ceti Team-Ups, Or just use the thread below!
Vault Breaker Explained
To Learn how Vault Breaker Works, please either watch this overview, follow the Bungie.net link, or continue reading below.
What is a Vault Breaker?
Vault Breakers utilize hit-and-run tactics to master the secrets of the Marathon’s Cryo Archive. They travel light and target the Archive’s many vaults in search of valuable loot and deeper access throughout the deck.
Vault Breakers’ strategic deployments challenge the UESC’s jurisdiction aboard the Marathon—applying constant pressure to defend the zone against Runner incursions. They strike during “quiet” moments—while rival crews are focused on Tau Ceti IV—to keep the UESC off guard and to maneuver with more focus, free of the chaos of a contested zone.
What is the Vault Breaker Mode?
Vault Breaker offers a roguelite PvE experience inside Cryo Archive, where you’ll take on progressively tougher Vaults across multiple runs. You’ll acquire Vault Data to upgrade your special Sponsored Kit (more details below), or spend that progress on gear in the new Vault Breaker Armory that features weapons, items, and more that you can bring back to your other adventures across Tau Ceti.
Note: All items and gear found in-run are restricted from exfil except event currency and rewards will only be available during the event period, so best to prioritize room for Vault Data and of course, items essential for you to make it to exfil.
How do I "Break" a Vault?
To access Vault Breaker, you’ll need to equip the free special Sponsored Kit found in the Vault Breaker Armory tab under the Events section.
This Sponsored Kit won’t be in its final form when you first grab it. At the start, the kit is at its weakest, offering only one standard weapon along with a small amount of equipment and consumables.
Each run, you’ll earn Vault Data, a special event currency that can be spent in the Vault Breaker Armory to upgrade the special Sponsored Kit for stronger PvE runs, or to purchase items and gear that can be used outside the event.
There are two tiers of Vault Data to earn:
Tier 1 Vault Data can be found in Vaults and then needs to be exfilled.
Tier One Vault Data is also awarded for killing a UESC Commander, and that reward is granted post-run whether you successfully exfil or not.
Tier 2 Vault Data can only be earned from consecutive Vaults solved in the same run and then successfully exfilled. You’ll need to manage your time and routes wisely. This will be especially tough for solo Runners.
