It has been confirmed that there is actually a nuclear steak in Call Of Duty: WWII. A PC player managed to be rewarded with the V2 Rocket whilst streaming for all to see.
You need to at least ONCE prestige all five Division’s in the game to unlock the V2 Rocket which is similar to previous nuke streaks in previous Call Of Duty titles.
Further more once you have unlocked the V2 Rocket you will need to go on a 25 kill gun streak to be rewarded with with the V2. It is unclear at the moment if it is a game ender as the video shows the gamer PwnStarz getting the V2 and getting enough kills to end the game anyway.
The V2 Rocket can be seen coming in from the 7:30 mark in the video,
