About this game

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!

How to play

On a computer, most games in this category use the arrow keys or WASD to move, the mouse to aim or select, and space or enter to confirm and act. On a phone or tablet, tap and swipe directly on the game area. If Aliens.io uses its own control scheme, it will show you on the title screen or in its in-game help.

Use the Fullscreen button above the description to expand the game to the whole screen — worth doing on smaller displays, and it removes everything else from view so you can concentrate.

Tips for a better run

• Give the game a few seconds to finish loading before you start pressing keys — early input can be dropped.
• Close heavy background tabs if the frame rate feels sluggish; browser games share your machine's resources.
• On mobile, turn the device to landscape for games designed around a wide play area.
• Found a bug or a game that will not load? Use the Report button above and tell us what happened.
