Game is played with mouse.
Alien Invaders io puts you right in the UFO, ready to snatch up anything that isn’t bolted down. Your mission: abduct humans, cows, trees—pretty much anything to grow your ship. The bigger you get, the larger things you can pick up. But watch out! Other aliens are roaming the same area, and if they’re larger than you, they can absorb you instead. It's survival of the biggest out there! Points add up after each game, letting you unlock cool skins for your UFO in the main menu. How to play: Move your UFO over anything you want to abduct and make sure the light beam’s big enough to cover it. Happy abductions!
