Multiply to survive!


You're a bacterium. You have just infected a body and need to multiply to fully take it over! But careful, the immune system will not go down without a fight...


Become as large as you can!


How to be a bacterium 101


Your bacterium cannot move a lot on its own. But it can hold onto nearby gray particles and drag itself to the grabbed particle.


It can also grab onto particles of other colors, which can be eaten.

Grab a particle with LMB (Left Mouse Button) and drag by holding RMB (Right Mouse Button)


Eat as much as you can! Once your bacterium ate enough food, it becomes too large to just be one bacterium - and splits into two!


It's that simple!


The immune system


You just want to grow, but the immune system is not a big fan of that. Sometimes, it may look for a fight. You need to stand your ground!


So far, you used your arm that can handle attracting yourself with particles. For fighting, you need to use your other arm - The battle arm!

Press SPACE to switch between the particle arm and the battle arm (attack mode)


Now, you can shoot deadly projectiles. Careful though - projectiles are made out of the resources you ate. Shoot too much and the shooting bacterium starves!

Shoot projectiles with LMB (Left Mouse Button) while the battle arm is selected
