ASTRONAUTILUS loopbreaker releasing 11/14/25

ASTRONAUTILUS loopbreaker is releasing soon!

loopbreaker is a large free update for ASTRONAUTILUS. It will add:

• new weapons, upgrades, and bosses

• a new zone and final boss after the original game's ending

• many polish and QOL changes

• an overarching storyline, with cutscenes and improved dialog

• 6 quests with unique gameplay tied into the story

• 24+ new music tracks, including guest tracks

On top of all of the new content, this update will give players a much deeper understanding of the world of CARCINA and all of the inhabitants within.

IMPORTANT UPDATE NOTES!!!

• Controller support will be removed, as there are additional required game mechanics that only logically work as intended with mouse and keyboard. Testing and supporting the many different types of controllers with these new mechanics is not something I wish to spend my time on.

• You will start on a new save file, as the save file format has been updated to support all of the new content. Your old save file will not be deleted and will still exist at 'save.txt', and the new save file will be created as 'save.ini'. These files are incompatible, and the game will only read the savefiles that match its format.

• The legacy version will be accessible with a Steam branch. The password for the branch is 'astronautiluslegacy'. More info on how to access beta branches is detailed here in official Steam documentation.

That should be all, looking forward to release!
