Game is played with mouse.
Alien Invaders io tosses you right into the action, commanding your UFO to swipe anything in sight to power up. Goal: Absorb anything from humans and trees to cars and animals to keep growing your UFO. The bigger your ship, the more massive stuff you can grab. But stay sharp! There are other players trying to grow their own UFOs in the same space, and if they’re bigger, they’ll try to absorb you. It’s an all-out battle for the biggest and baddest UFO. Points rack up with every round, letting you earn cool new UFO skins in the menu. How to play: Hover over stuff to pull it in, making sure your UFO beam is big enough to take it. Abduct all the things and watch out for bigger aliens!
