Game is played with mouse.
Alien Invaders io is all about gobbling up the world with your flying saucer, starting small and working your way up to absolute UFO dominance. At first, you’re just a tiny invader scooping up street signs, benches, and anything else that fits inside your ship. But as you absorb more, your saucer grows, unlocking the ability to consume cars, buildings, and eventually even other players. The goal? Be the biggest, most unstoppable force on the map before the round ends. How it Works: The more you eat, the bigger you get—it’s that simple. But it’s not just a free-for-all; size matters. If a player is bigger than you, they can swallow you whole, erasing all your progress in a second. That means you’ve got to be strategic about what you pick up and when. Stick to smaller objects at the start, grow at a steady pace, and avoid anyone who looks like they could make you their next meal. As you level up, the power dynamic shifts, and suddenly, you’re the one hunting down weaker ships. Every match is a race against time and competition. The city is packed with objects to consume, but so is everyone else. Move fast, plan your route, and don’t hesitate to cut off smaller UFOs to slow them down. The more aggressive you play, the higher the risk—but also the bigger the rewards. If you dominate early, you’ll control the entire field by the time the game reaches its peak. And for those who like to stand out, different skins let you customize your ship to make sure everyone remembers the alien that ate them. Pro Tips: Prioritize clusters of small objects to level up faster at the start. Keep moving—staying still makes you an easy target. If you're in trouble, use obstacles to block bigger ships from getting to you. And once you hit max size? Chase down anyone who’s left and let them know who runs this invasion.
