In the third part of the game Alien Attack 3, you again have to repel the attack of the aliens. Their ship landed in the south of America near a small town. The landed troop of soldiers captured the city and began to export the inhabitants to the ship for experiments on them. You as part of a detachment of soldiers will have to enter the city and destroy all the aliens. Moving along the streets of the city, carefully look around. When you see the enemy, catch it in the sight of your machine and open a hurricane fire. Try to move around constantly to make shooting difficult for you. When killing an opponent, you can drop a weapon that you can pick up and use against enemies.
