In the game Sniper Mission 3d you will serve as a sniper in a secret unit. You will need to travel the world and complete secret missions. Picking up a sniper rifle you will find yourself in position. For example, it could be the roof of a building. You will need to inspect the streets of the city through an optical sight and find your goal. Catching her in the crosshairs of your sight will fire you. A bullet hitting a target will destroy it, and you will receive points for completing the task. If you miss, then the mission will fail.
