In Bacterio you play as a small bacterio equip with the ability to fire projectiles and boost your speed your goal is to control the middle zone and boost your points whilst fighting off enemy players.
Movement is controlled through the mouse, shooting is done through left click and right click can be used to increase your speed/boost.
You are a strong independent bacteria, simply put its a free for all out there, everyone will be trying to kill you so show them no mercy. Dotted around the map are food that can slowly boost your score up although the most efficient way to climb your way up that leader board is to control the middle zone and kill anyone that dares oppose you! You have the ability to shoot projectiles and use boost which can be very useful for dodging on coming attacks, as well as this you have 3 upgrades that you are able to collect in the form of a turtle shell, a pair of wings and a crown. The shell indicates that your character has more armour/max health meaning you can take more hits, the wings indicate that you have increased boost/speed and the crown is a sign of Bacterio royalty! If you have the crown that means you’re number 1 and everyone will most likely try to claim your head.
