Legendary Sniper Achievement
Prevent Wolff from escapingThis is story related and cannot be missed. This can be earned on any difficulty.
At the end of Mission 10, 'Brandenburg Gate', as you start your climb up the tower, a short cutscene will play showing Dr. Wolff getting into his vehicle. Continue climbing to the top and once you reach the roof, you will see the objective marker driving away. Take position, aim and shoot Wolff, causing his vehicle to flip over.
