I finally got the DLC stuff figured out! If you have purchased the game (or if you purchase the game while we are still in early access), you will get the original sound track DLC for free!
This should update automatically, and everyone that has purchased the game so far should see the DLC as part of the game.
Please post in the forums if anyone has any problems, or contact me at [email protected].
Enjoy!
*edit*
The DLC should appear in:
C:\Program Files (x86)\Steam\steamapps\common\We Slay Monsters\soundtrack
on windows, or
/Users/[OS USER NAME]//Library/Application Support/Steam/SteamApps/common/We Slay Monsters/soundtrack
on OSX.
In the next patch (coming soon!) there is a button on the main menu that opens this directory for you.
