It looks like Sledgehammer Games managed to work in a hidden scorestreak for Call of Duty: WWII’s multiplayer component. Once unlocked, the V2 Rocket scorestreak acts in much the same manner as the Nuke scorestreak from previous Call of Duty titles, but unlocking the ability to use it will take a little time.
According to this Reddit post and accompanying livestream footage, a player has to first prestige at least once with all five Divisions in order to earn the ability to equip the V2 Rocket. Then, to actually utilize the V2 Rocket during a match, the player has to go on a 25-kill streak without dying, an impressive feat to be sure, and one which is suitably rewarded with a game-ending explosion.
Call of Duty: WWII is available now for PC, Xbox One, and PlayStation 4.
