Axion is now available on itch.io!
Axion left early access on Steam in December 2015. I have now made the game available on itch.io as well!
The itch.io version of the game is DRM free and includes it's own content distribution and automatic updates. If a patch is released on Steam, the itch.io version will also detect the update and prompt you to install the latest version which it will then do for you if you choose to update. You will also receive a Steam key with your purchase.
A significant amount of updates have been released for Axion since the game was last updated here on Indie DB. To see a full change log, check out the news page on Steam here:
