Mastering the Overkill Perk in MW3: Equipping Two Primary Weapons

Modern Warfare 3 players can no longer use the Overkill Perk to run two primary weapons simultaneously. Instead, they can equip the Gunner or Overkill Vests, which allow for the use of any combination of primary weapons. The Gunner Vest, unlocked at Level 20, provides maximum ammo and faster reload times, while the Overkill Vest, unlocked at Level 50, enables reloading while sprinting and faster weapon swapping. Using Double XP Tokens or playing during Double XP events can expedite the process of unlocking these Vests.
