How to get digital art/soundtrack code

[Arsonicz]

I just preordered the game, how do I find the code to redeem the soundtrack and digital artbook?

Once the game unlocks, it'll be automatically downloaded. Just right-click the game in your Library, go to Local files tab and browse local Files. There should be a folder called Bonus or something along those lines.

First you should ask yourself a different question : Even if you had this code, whatever would you do with it?
