Good evening sniper. For your tenth mission, you must defend the aircraft where our diplomat and the leader you just helped apprehend as they discuss a peace treaty from enemy radicals who wish to keep the war going. This operation Is a 10 mission campaign, but due to the war, we can only afford to send you with 520 ammo to use over the course of the campaign. Use to much, and the mission has failed. Look around with the arrow keys. Hold the spacebar to use the scope, and release to fire.
