The Proteus is a sniper rifle that was added to Call of Duty: Infinite Warfare in the June 27th, 2017 update. The Proteus is very unique as it is a pump action sniper rifle/shotgun hybrid, and it behaves as a buckshot while hipfiring and as a slug while aiming down the sniper scope. Shotgun mode has around eight pellets per shot, while in Sniper mode it only has three pellets.
