MW3 & Warzone September 5 update patch notes: BAL-27 exploit & Bunker Buster fix

Modern Warfare 3 and Warzone’s latest update made a few minor bug fixes, addressed an exploit with the new BAL-27 aftermarket part, and addressed an issue with Bunker Busters in battle royale matches.

In Season 4, a glitch with Trophy Systems made Bunker Breakers unusable for the duration of the match. Raven Software resolved it in the Season 5 update, but the patch introduced another issue that allowed them to obtain an absurd number of Bunker Busters.

The development team quickly sprung into action and temporarily disabled the killstreak. Now that they are back, players found a problem with them getting used too frequently in the same area, so this update makes it harder to use more than one at the same time.

Meanwhile, the JAK Deathmarch turns the BAL-27 into an energy burst gun with a short charge-up time. The aftermarket part performs especially well in multiplayer, but an exploit resulted in infinite ammo.
