The latest update for Modern Warfare 3 and Warzone introduced some minor bug fixes, resolved an exploit involving 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 rendered Bunker Breakers unusable for entire matches. Raven Software fixed this in the Season 5 update, but the patch created a new issue, allowing players to acquire an excessive number of Bunker Busters.

The development team quickly responded by temporarily disabling the killstreak. Now that it's back, players noticed they were being used too frequently in the same area, so this update limits how many can be deployed simultaneously.

Additionally, the JAK Deathmarch turns the BAL-27 into an energy burst weapon with a short charge-up time. While effective in multiplayer, an exploit caused it to have unlimited ammo.
