The Sniper Rifle only appears in certain missions of Dead Trigger 2. When used in missions, the player is only allowed a scoped-in view and, strangely, must manually guide the bullets. It's designed for gameplay purposes. The sniper rifle will always one hit kill the Zombies regardless of the point of impact. The sniper has indefinite piecing ability, it has the ability to pierce through an infinite number of zombies until the bullet hits a wall. However this is limited by the firing angle of the shooter in the sentinel mission as it almost always hits the ground before hitting many zombies in a row.
