The character customization will remain the same as it currently is in the alpha. (The menu interface will look better though.) I considered adding individual parts to the character customization which can be unlocked and swapped in the customization menu (Helmet, arm/leg protection, etc...) but i'm somewhat limited to the engines capabilities and the animation technique which i use in the game. But this is something which i would like to add in a potential sequel. :)
The game will be released on Steam with a regular launch.
