This is from a Humble Capcom Bundle.
For the future winner: I apologize in advance if I take more than 24hrs to send you the key. I don't always check Steamgifts due to my obligations. That being said, I'll try to send it as soon as posible.

EDIT: I also have the key for the upgrade to deluxe edition, so in case I can only give one key from this site I suggest the winner to add me on steam to send you the extra key

Cheers!
