A few questions

I remember backing the game, been so long ago I do not remember which one I payed for sorry memory is bad lol… I also received an email from Xsolla regarding a cd key with detailed info on how to add the game to my Epic Store library. But i am unable to do so…

this is what comes up when trying to redeem the code.
Sorry, you do not have a prerequisite to fulfill the redemption code.

that email was about the Season Pass, which doesn’t work without the full game. The keys to the full game will be sent out on Dec 3rd
