Micro.io is a multiplayer cell survival game where players compete to grow, hunt, and dominate a microscopic battlefield. Micro.io challenges you to consume smaller organisms, avoid larger predators, and use tactical mechanics like splitting and mass ejection to outplay opponents. Every match is a fight for survival as you climb the leaderboard and become the largest organism in the arena.
How to play
In Micro.io, your goal is to grow by collecting glowing food particles scattered across the map. As your mass increases, you can absorb smaller cells and eliminate rivals. However, larger cells can easily consume you, so careful movement and quick reactions are essential. The more mass you gain, the higher you climb on the leaderboard. Successful players balance aggressive attacks with smart escapes.

Core Mechanics
Movement is simple and responsive. On the desktop, your cell automatically follows your mouse cursor. On mobile devices, you steer using the on-screen joystick.
Key gameplay actions include:
Consume food: Move across glowing particles to increase your mass.
Absorb smaller cells: Larger size allows you to swallow smaller organisms instantly.
Avoid bigger opponents: If another cell is larger than you, escaping quickly is the only option.
Split and mass ejection strategy
Micro.io introduces tactical abilities that create deeper gameplay:
Split attack: Press Spacebar (or split button on mobile) to divide your cell. One piece launches forward, allowing you to capture distant targets quickly.
Mass ejection: Press W (or the eject button on mobile) to release a small amount of mass. This can feed allies, bait enemies, or help you move through tight spaces.
Using these abilities at the right moment can completely change the outcome of a match.
Virus interaction
Green spiked viruses appear across the map and act as environmental hazards. Large cells that collide with them will break into smaller pieces, making them vulnerable. Skilled players can also feed viruses with ejected mass to trigger them and launch them toward opponents as a weapon.
