About the Game

Welcome to Bacterian!

Hidden deep inside, our immune system is locked in a constant fight against germs and pathogens, ensuring we stay strong and healthy. Bacterian lets you experience this struggle firsthand in an exciting action-puzzle take on the classic Sokoban-like gameplay.

In order to stay alive, you have to keep moving. Always! Be quick with your tactics and outsmart the hostile pathogens. Put blocks in their way to change their paths, use teleports or trap them in closed areas - all this to finish them off before they catch and infect you. 

As a fearless Immune Cell, you can fight back! Squash the pesky invaders by sliding blocks onto them and make sure to get rid of them all. Be careful though - germs vary in looks, intelligence, abilities and speed, so every encounter requires quite a different approach.

Explore diverse levels set throughout every corner of your body... and beyond! Defend not only yourself, but also your animal friends. Remember - the further you go, the more advanced mechanics and solutions you'll face. Can you overcome troublesome diseases once and for all and keep everyone safe?

• Music and sound effects that spark a wave of 8bit nostalgia
