Marathon’s Vault Breaker Will Run Until August 18 in Update 1.1.5.2
The notes also raise V22 Volt Thrower damage from 12.6 to 14.4 and add mods, Patch Kits, and a grenade to free Sponsored Kits.

Marathon Update 1.1.5.2 will keep the Vault Breaker mode running until August 18. Bungie’s official update notes also detail better free Sponsored Kits, weapon adjustments, and fixes for rewards, progression, and store displays.
The Vault Breaker extension comes with more stock for some limited offers. Bungie also corrected the Key Template Armory reward description so players can see that it only grants Cryo Archive keys.
Free Sponsored Kits now provide random Enhanced green mods on their starting weapon, an Enhanced Patch Kit stack, and one random grenade. Combat changes include a damage increase for the V22 Volt Thrower, a larger base magazine for the KKV-9SD, and the return of the Prestige-quality Overlocked Delimiter mod for the V85 Circuit Breaker.
