About Aliens.io
Alert! Alert! The alien invasion has begun! Earth is under attack! Ever wanted to take over planet Earth? Feel what it’s like to be an alien invader? Abduct people for secret experiments or destroy cities to show the world who really rules the universe? Then welcome to Crazy Spaceship! Destroy buildings, abduct all living beings, and spread chaos in your UFO! The more you abduct, the bigger you grow. And the bigger you are, the bigger the objects you can abduct! But watch out! Never trust a fellow alien! They also want to rule the earth, and if they get bigger than you, they’ll swallow you whole! Be careful! Don’t get abducted! Sound easy? Too bad you’re almost out of time! Invasions only last 2 minutes, so hurry! The clock is ticking!
It's a straightforward arcade game that gets out of your way and lets you play. Whether you want a quick five-minute break or a longer session, it runs smoothly on just about any device.
Two quick pointers before you dive deep: Learn the dodge before the attack — survival keeps you in the game longer than damage. When you die, ask "what killed me?" before respawning. Patterns repeat.
