What the developers have to say:

Why Early Access?

“The core gameplay loop and most key features are complete and evaluated by beta testers. However, there are still many things to improve and balance, as well as possible improvements to implement based on community feedback. Listening to you, the players, is our top priority, because we want to make a game that you enjoy. A game's community is the most valuable resource for useful feedback, so we strive to engage with the community as much as possible.”

Approximately how long will this game be in Early Access?

“We plan to release the full version by the end of the year.”

How is the full version planned to differ from the Early Access version?

“We want to tune the balance based on the player feedback, implement some QoL features and possibly a freeplay and coop mode.”

What is the current state of the Early Access version?

“All the features listed on the game Steam page are available in the current version.”

Will the game be priced differently during and after Early Access?

“No, we don't anticipate a price change.”

How are you planning on involving the Community in your development process?

“We welcome any feedback via Discord or the community board, we'll try to reply to everything and implement as much of it as possible!”

About This 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?
