You’re definitely going to have to stock up on ammo for Aliens Attack, one of our favorite action games that pits you against endless hordes of vicious invaders. Like many other alien defense titles online, you are the last line of defense. Your daring mission is to blast as many aliens as you can while dodging their laser fire at the same time. Our advice? Aim for the higher value targets first, and keep moving! It’s hard to get more classic than that.


Even more deadly than the legions of alien ground troops are their rockets and lasers, which target the planet’s most valuable structures from above. In Planet Defense, one of our most highly acclaimed alien games online, you are given the huge responsibility of defending these military bases with anti-ballistic missiles fired from a single turret. As one of the most fast-paced alien shooting games online, Planet Defense requires lightning-fast reflexes and decision-making if you are going to make it out alive.
