Sift Heads Assault 3

Aim and shoot to kill your enemies. Hide behind objects for cover, and aim and click your mouse to shoot the enemies in the distance. Be careful of enemies sneaking behind you trying to kill you. Move around using the A and D keys, R to reload, and Spacebar to pick up items. Avoid getting shot or your health will go down. Lose all health and you lose the level. Kill all the enemies in sight to win the level.
