Marathon Mid-Season 2 Update: Vault Breaker, WSTR Buff, and Grenade Limits

Update 1.1.5 drops July 21st, and it's the most substantive mid-season delivery Marathon has seen. Three things are moving the meta right now: the WSTR Combat Shotgun - Shotgun is back from its timeout corner with a genuine buff, the ⬢ D54 Battle Pistol - Pistol gets range and precision nerfs that meaningfully alter its TTK, and a sweeping grenade/throwable infil cap changes the opening economy of every single run. Player reaction is not yet available — the patch hasn't landed as of this analysis, so community consensus is pending.

The WSTR Combat Shotgun is the headliner. Damage goes from 85 to 100, which is a real number — but Bungie is not handing back the full launch menace. Spread increases 20% across all stat tiers, aim assist falloff tightens meaningfully at the top end, and the precision bonus multiplier is stripped entirely (as it is from the Misriah 2442 - Shotgun — ballistic shotguns now live and die by pellet coverage, not headshot fishing). The resulting profile is a weapon that two-shots a grey-shield target at 3 meters with a base WSTR, pushing to 7 meters with a fully invested one. That's honest close-quarters pressure without the mid-range terror of launch. The ◈ MIPS Slug Converter - Barrel MOD - Prestige barrel — which sources list as adding fire rate and stability — now matters more for closing the gap between grey and top-end performance. I'm moving the WSTR up from C to B. Not a meta weapon yet, but no longer an obvious pass.

The D54 Battle Pistol takes a quieter but structurally significant hit. Precision multiplier drops from 1.5x to 1.38x, and damage falloff range is cut 10% across all tiers — sources list the top-end falloff maximum dropping from 72 meters to 64 meters. The practical result: downing a grey-shield target now costs three precision bursts instead of two, and four against a purple shield instead of three. The pistol was genuinely out of band for a sidearm, and this lands it in a more honest position among secondaries. Still a capable light-round option for ammo sharing with AR builds, but the "free ranked advantage" feel it had is gone. I'm holding D54 at B-tier — its floor is intact, its ceiling trimmed.

The throwable infil restriction is the change most players haven't fully priced in yet. Starting July 21st, a hard limit of 2 total throwables — any combination of Bubble Shields, Chem Grenades, EMP Grenades, Flechette Grenades, Frag Grenades, and Heat Grenades — can be brought into a run. Scavenged grenades in-run are still fair game. This has two immediate ranked implications. First, grenade-stack entry strats on Cryo Archive are dead on arrival — the coordinated spam that was flattening high-level combat won't survive the infil gate. Second, and more quietly important: Bubble Shield stacking, which was extending extraction windows and making certain extraction chokepoints nearly unbreakable in squad ranked, is now capped. Squads relying on layered Bubble Shields to hold exfils will need to rethink their exit sequencing. Triage - Support squads and Destroyer - Combat anchor compositions lose a layer of insurance, but the core loop of both shells is untouched — this is a loadout-building constraint, not a kit nerf.

Vault Breaker opens July 21st through August 4th: a roguelite PvE mode inside Cryo Archive, available solo, duo, or trio regardless of Runner Level, using a free Sponsored Kit that upgrades via Vault Data currency. Critically, in-run gear does not exfil — only Vault Data and event rewards carry over. The Vault Breaker Armory stocks a daily rotating Deluxe weapon, Prestige weapons, and Cryo Key Templates, all purchasable for use in standard runs. For ranked players, the Prestige gear pipeline is the piece to watch: this is a two-week window to build out a stronger standard loadout before the grind returns to normal.

The Cradle Evolution system also arrives at mid-season: max out your Cradle, reset to zero, earn one additional maximum Energy point, and unlock exclusive cosmetics including Runner shell styles. Bungie also reverted the 25% Cradle progress reduction that was previously applied — progression is back to full speed. If you were sitting at or near cap, the reset path is now the highest-leverage Cradle move you can make.

For ranked, the meta order is not upended — the structural shells hold their positions, the grenade cap is a constraint on preparation, not on kit power. But the WSTR re-entering viability and the D54 losing its free-kill TTK window are both shifts worth front-running before the lobby catches up on July 21st.
