A new Vest and a new Gear perk are joining MW3 for season four. The Mission Control Vest speeds up your scorestreak/killstreak progression by reducing kills required by one, and Scorestreaks by 125 score.

The Compression Plate, meanwhile, will let you begin to immediately regenerate health after getting a kill with a primary, secondary, or throwing knife/throwing star.

New killstreaks

Four new killstreaks have arrived, including the return of the DNA Bomb and the IMS, along with the Loitering Muniition and Missile Drone. The DNA Bomb is like the MGB nuke, except it won’t end the game after wiping out the entire enemy team, and it’s unknown how many kills it takes to unlock.

New Aftermarket Parts
