Notably, the M16 and Holger 556 assault rifles received massive buffs to their recoil and gun kick control, further boosting their accuracy in mid to long range encounters.

Conversely, several submachine guns, as well as the Haymaker shotgun with the conversion kit, were nerfed.

The newest sniper rifle in the game, MORS, had an important fix for its shot alignment.
