Modern Warfare 3 June 11 update patch notes: Kar98k fix, Sidewinder buff, more

Patch notes for Modern Warfare 3’s June 11 update outline a range of changes, including those impacting the Kar98k, Sidewinder, and more.

Modern Warfare 3 Season 4 went live late in May 2024, unleashing new maps, modes, Operators, and weapons on the ever-evolving experience.

Within a matter of days, MW3 developers had prepared a litany of tweaks for a June 4 patch that addressed Killstreak bugs and distracting UI-related errors.

Now the shooter has received yet another layer of fine-tuning, evident in the patch notes for its June 11 update.

Modern Warfare 3’s June 11 patch is now live

The June 11 update for MW3 fixes errors that affected the Kar98k rifle; the mismatched CS15 Scarlet Box Laser Attachment has been removed, for example.

Meanwhile, the Sidewinder has received a buff, thanks to several adjustments targeting the JAK Thunder LMG Kit.

Fixes for the UI and Killstreaks also sit center stage. Notably, the Swarm Killstreak should no longer have an issue with drones failing to patrol on Emergency and Tokyo maps.
