Marathon Update 1.1.5.2 (2026): Vault Breaker Extended to Aug 18

Bungie just bought Vault Breaker two more weeks. The mode was supposed to close on August 4, and instead of letting it die on schedule, Update 1.1.5.2 pushes the end date to August 18 while quietly walking back one of the more hated weapon nerfs from earlier this Season. There is also a fix for a Cryo Archive exploit that was probably inflating a lot of people’s reputation grind without them realizing it.

This is a mid-season maintenance patch built around one big scheduling change and a handful of targeted weapon and economy fixes. If you already burned out on Vault Breaker before the original August 4 deadline, the extension gives you a second wind and slightly deeper Armory stock to spend leftover Vault Data on.

On the combat side, the V22 Volt Thrower is the headline change. It is not back to where it was before the July nerf, but the gap closed noticeably, and Bungie’s own developer note frames it as a partial revert rather than a full reset. The KKV-9SD and V85 Circuit Breaker both got smaller, more mechanical fixes rather than balance overhauls.

Vault Breaker launched as Marathon‘s first PvE-only mode, dropping Runners into Cryo Archive to clear escalating vaults with nothing but UESC forces standing in the way. It was originally billed as a two-week experiment, and Bungie has been upfront that it exists to gather feedback ahead of the full PvE mode planned for a future Season. The studio clearly liked what it saw, because instead of shutting the mode down it just extended the whole thing.

The patch note also confirms Bungie increased stock on some limited Armory offers to match the longer window, and fixed a description bug where the Key Template Armory reward was not correctly labeled — it only ever awarded Cryo Archive keys, the note just didn’t say so clearly. Neither of those changes affects how the mode plays, but they matter if you were holding off on a purchase because the listing looked wrong.

Who Actually Benefits From the Extension

Not everyone gets the same value out of two extra weeks. Where you land depends on how far into the Vault Breaker grind you already got before this patch.

Already Maxed Your Sponsored Kit?

If your Sponsored Kit upgrades were already capped before the extension, the added time is mostly about spending leftover Vault Data on the restocked Armory offers rather than earning more currency.

Skipped Week One Entirely?

Players coming in fresh now have a full second run at both Vault Data tiers, and the mode itself has not gotten any easier to solo since the dedicated solo queue difficulty tuning landed in an earlier hotfix.

Chasing the One-Per-Event Prestige Gear?

Prestige Armory items were capped at one per event before the extension. That cap has not been mentioned as changed here, so treat the extra fortnight as more time to earn the currency, not a second shot at items you already claimed.

Short answer: closer, not equal. Bungie’s own developer’s note lays out the math plainly — the Volt Thrower’s damage went from an original value of 18, got cut to 12.6 in a balance pass, and now climbs back up to 14.4. That is a real buff, but it still leaves the weapon meaningfully weaker than it was before the nerf ever happened.

The other change worth noting on the Volt Thrower is that its tracking speed now decays over the first 1.2 seconds of a projectile’s flight, capping out at a 30% reduction, and the weapon spends about 20% less time at its 540rpm heat plateau before it starts cooling down. Both changes are aimed at the same thing: making the weapon feel less like a guaranteed hit-and-forget tool at range while still rewarding players who land shots early.

The KKV-9SD change is easy to undersell. A jump from a base magazine of 23 up to 28 rounds sounds small on paper, but on an SMG that lives or dies on how many bodies it can drop before a reload, that is a genuine quality-of-life shift. The patch also quietly fixed certain magazine mods that were not granting their listed extra rounds at all, which is the kind of bug that makes a weapon feel worse than its own stat sheet promises.

Outside the headline changes, this patch cleans up a currency exploit and a couple of storefront bugs. None of these are flashy, but at least one of them was quietly worth real progression to players who found it.

• Cryo Hatch farming closed Repeatedly opening the Cryo Hatch in a single match was granting unintended amounts of faction reputation and Season XP; it now only pays out once per match, and every other Cryo Archive action that had its rewards disabled while the fix was investigated is back to normal.
• LUX purchases fixed Buying Rewards Pass items with LUX was sometimes failing to grant the Salvage or Schemas that should come with the purchase.
• Store Catalog display fixed Some bundle items that were supposed to also show up in the Catalog section were not displaying there correctly.

The Item Economy side also got a buff nobody asked for out loud but plenty of people will notice: free Sponsored Kit Boosts, the version of Vault Breaker’s starting loadout available to players who haven’t bought a paid kit, got upgraded. The free kit’s starting weapon now rolls with a random Enhanced (green) mod attached, instead of showing up bare.

• A random Enhanced (green) mod on the starting weapon
• 1 stack of Enhanced (green) Patch Kits
• 1 random grenade — smoke, heat, or claymore

It is a small thing, but it closes some of the gap between a free run and a paid one, which matters if you are testing the mode before committing currency to it. For a deeper look at what Vault Data actually buys and how fast it accumulates, the Vault Breaker Vault Data farming guide covers the currency side in more detail than this patch note does.

A few habits from before this update are now either pointless or actively wasting your time. Worth adjusting before your next session.

• Don’t bother repeat-opening the Cryo Hatch for extra reputation — that loop is closed and only pays once per match now
• Don’t write off the V85 Circuit Breaker’s Prestige mod as broken — it’s re-enabled, so check your loadout if you swapped it out earlier
• Don’t assume the Volt Thrower is back to full strength — it’s a partial revert, not a reset, so re-check the range you were used to before the nerf

The Volt Thrower situation specifically is going to cause confusion for a while. Expect community chatter to overstate the buff since the developer’s note openly frames this as only a partial correction — treat 14.4 damage as the real number, not the weapon’s old identity.

Depends on how much Vault Data you left on the table before August 4 was the deadline. If you were still mid-grind on Sponsored Kit upgrades or hadn’t hit the Tier 2 Vault Data cap, the extension is free value — same mode, same rewards, more time to earn them. If you already squeezed everything useful out of the Armory, the extra fortnight mostly just means restocked limited offers to spend leftover currency on.

It is a maintenance patch, not a reset. Nothing here changes what Vault Breaker fundamentally is, it just gives it a longer runway before Season 3’s full PvE mode replaces the experiment entirely.

For players still mid-grind on Vault Breaker, this is a clean win: more time, more Armory stock, and a couple of weapon fixes that make loadouts feel less punishing. For anyone who already cashed out their Vault Data before the original deadline, there isn’t much new reason to log back in beyond the Volt Thrower buff.

It’s a solid maintenance patch, not a system, and the real story is that Vault Breaker survived long enough to earn a second window before Season 3 takes over.
