Bacteria is the main resource in the game. It is used for purchasing and upgrading colonies and attacking planets.
Bacteria can be obtained in the following ways:
- by tapping on the screen
- automatically, if the player has purchased some colonies
- from red bacteria bonus
- from failed colony irradiation or bacteria evolution
The player loses all his bacteria when attacking a planet or entering a Black Hole. In doing so, more valuable resources are obtained and new bacteria can be spawned faster.
