The update specifically targets the Aftermarket Parts feature, which provides players with the ability to modify weapons they have already mastered, going beyond regular attachments.

To access the Conversion Kits, players must complete in-game challenges that become available once their supported weapon reaches its maximum level. These kits offer a unique and unexpected experience with familiar weapons, allowing players to transform them into entirely new guns.

In a statement on the Call of Duty website, co-developers Sledgehammer Games and Treyarch expressed their aim to create Conversion Kits that enhance a weapon's capabilities without overshadowing its original purpose. Taking into account player feedback and a thorough review of the recently released Aftermarket Parts, significant changes have been implemented to provide a more satisfying experience.

The developers have refined their approach to balancing Aftermarket Parts, ensuring that they are powerful and worthy of the effort required to obtain them. The primary focus is to create an enjoyable and balanced gameplay experience for players.

In addition to the weapon customization adjustments, the update includes a minor change to the Zombies mode by introducing Warlord randomization.

Call of Duty Modern Warfare 3 was launched in November 2023, and Season 1 Reloaded was released earlier this month, marking another milestone for the popular game series.

While detailed patch notes for Call of Duty Modern Warfare 3 Season 1 have not been provided, players can expect improvements to weapon customization and an enhanced gameplay experience.

The update demonstrates Activision's commitment to continuously improve and fine-tune Call of Duty Modern Warfare 3, delivering an engaging and enjoyable gaming experience for its dedicated community of players.
