You are a sniper behind enemy lines on D-Day, tasked with picking off the bad guys as the Allies consolidate their beachhead.
Well, not really, though I do admire your active fantasy life. Still, it's a relaxing pastime, sort of like Where's Waldo, but with fatal head shots.
If you can, identify all the enemy snipers and eliminate them first. Because once you fire that first shot, they start looking for you. All of your targets will be within the white boundary-lines indicated on the briefing screen.

Warning: Some sound effects, mainly the sound of your gun and ricochets. There's no muting, so turn down your speakers first if need be.
