Brains of the OperationG 15

No trickery required here, just bring your favorite scoped rifle and blast Moller in the head. He’ll pause for a moment above the stairs to the right before walking down to his car, that’s the best time to take him out. You could also wait for him to get in the backseat and shoot before he drives off. Or be Mr. Badass Sniper and go for the moving shot, it’s up to you!
