Aliens.io is a fast paced browser arcade game where you pilot a UFO to invade Earth, abduct people, destroy buildings, and compete against other players. Each match lasts about 2 minutes. You earn size and power by collecting humans and objects. As your UFO grows, you can grab larger targets and dominate the arena. The core challenge is to grow faster than rival aliens while avoiding being abducted yourself.
Gameplay is simple to learn, but hard to master. Players move around a compact map, follow on screen markers to reach checkpoints, and race to complete objectives before time runs out. The game mixes casual arcade action with competitive .io style multiplayer. Quick matches, clear objectives, and direct player conflict make it ideal for short plays on desktop or mobile browsers.
- Objective: Abduct and destroy to gain size and points.
- Mechanics: Grow by collecting living beings and objects; bigger size allows bigger captures.
- Competition: Other players can eat smaller UFOs and compete for checkpoints and high score.
- Match length: Short, intense 2 minute invasions designed for repeat plays.
