There's a little known secret in Call of Duty: WWII. It's the legendary "nuke killstreak", a destroyer of worlds that every competitive player dreams of using in multiplayer one day.
The thing is, its existence isn't directly advertised in the game, and it's definitely not easy to unlock.
First off, I should be clear that it isn't technically a "nuke" per se, but rather a V2 rocket, what was the world's first long-range guided ballistic missile, crafted by the Germans during World War 2. Though, its effects are similarly devastating to a small nuke in terms of its video game application, capable of instantly handing you a victory as everyone on the map is blown to smithereens.
Here's what it looks like in action:
The bad news is that it's quite difficult to unlock.
To unlock the V2 rocket you need to prestige all five divisions at least once. Divisions are essentially Call of Duty WWII's classes, broken up between Infantry, Armored, Airborne, Mountain, and Expeditionary.
It goes without saying that this takes quite a bit of time to achieve, but the results are well worth it.
Oh, and it's worth mentioning that the V2 rocket is a 25-killstreak, which is pretty dang hard to accomplish. By the time you unlock one, you've basically already won the match anyway. Hey, at least you get to cap things off with a display of fireworks.
