Führerious Repetition Achievement
Wolf Mountain - Kill Hitler 5 times.When you finally have Hitler in your sights, before you kill him, save your game. That way, you can just reload it after each time you kill him. It doesn’t matter how he is killed, so you can get creative if you want.
In your reloads, try and shoot him in the testicles to unlock Das Familienjuwel (15G).
