The latest patch for Call of Duty: Modern Warfare III has arrived, bringing with it a series of weapon balance changes, bug fixes, and stability improvements.

For weapon balance changes, Sledgehammer Games said its main goal with the latest update was to nerf the FR 5.56 and DG-58. Both will now require two headshots to kill an enemy with a single three-round burst. Submachine guns get a change, too, with the Striker seeing its maximum damage range increased and the AMR9 decreasing the sprint-to-fire time by 30%.

Sledgehammer said these updates to SMGs specifically should make them more consistent and viable when compared to other SMGs in their class.
