And some new 2 weapon options for each class.and loving your game keep it
V0.6 (and some other future updates) will be the last free versions. To have access to some future release, you will have to pay the game on itch.io. anyway it will be some few cents.
For the full release on steam it will have a final cost. I think it will not more than 10€. Anyway it will aviable even on itch.io if you has already paid for it while it was in development.
