I have the steam version of Serious Sam 3 BFE Gold Edition. It's in my inventory so I can gift it to you.
The store page has it pegged for $49.99 so all I'm asking is for $30 amazon gift card.
I got an email about a month ago with a code to unlock this card.
It's a Garchomp EX promo card.
First person to message me gets the code.
Update: it's gone. Sorry!
