Our planet is under attack by creepy alien creatures in Alien Onslaught. It seems their civilization is no worse developed than ours, so the battle will be almost equal. However, the surprise of the attack played a role and the aliens managed to land a large landing party of technicians and soldiers. You will have to fight with different types of weapons. First, you'll climb a hill to shoot at the flying ships with a powerful gun. Next, get into the tank and destroy all enemy tanks. To avoid missing anyone, follow the round locator. Red dots are enemies in Alien Onslaught. At each level you will have a special task. Not like the previous one.
