Just got my refund. The email I recieved was worded as follows:

Hello,

Normally we do not refund games that have been downloaded, but I now realize how unclear our multiplayer notice was. I have asked our product team to change its contents, to make it more clear that this is what the multiplayer experience in our version looks like.

In light of this, I can either offer you a refund, or four $9.99 bonus codes, if you prefer store credit in such a form.
Please let me know which you prefer, and send me this payment's Transaction ID, for verification purposes.

Regards,
Firek
