I am currently struggling to beat the Sniper in the Sniper Duel does anyone have any tips such as positioning, which window is easiest to kill him in, etc ?  He kills me evey time with one head shot, I guess he is a better sniper than me so far. I am currently doing the game on the level below veteran.

shoot him before he shoots you duh.......

"shoot him before he shoots you duh......."

so

did it work?

Well what i do to take down snipers is running in the open until they shoot me, once i know where they are i hunt them down.

"shoot him before he shoots you duh......."

I thought that part was really hard as well.   I saw him running around then just waited for him to poke his head out.  I also think there's a white dot above his head. Not sure though.

"so

did it work?"

I just plug the bastard and sprint off

I'm playing through the game on Veteran, and the german sniper will kill you with one shot.  After hiding behind the wall by the steps, I let him fire off one shot, and then I ran behind the window.  He fired a second shot.  Once he started sprinting to another window, I fired as he was running and managed to kill him.  Trying to shoot as he's setting up to shoot was frustrating.  Shooting while he was on the run was pretty easy though.
