Green Man Gaming is a joke. I purchased the stupid max payne 3 DLC thing for $4, thinking it was the game with all the DLC, but it's only the DLC. So I go back to buy the game for $8 and it won't go through on Papyal for some reason. I try my credit card and it still won't go through, then I get an email saying I was charged for the game anyway and I obviously never got the game. That website is junk. There is no contact email, and that fake phone number they put up doesn't go through to anyone.
Here is a key for a free copy of the Max Payne DLC - GFR5X-VDR4A-48WFF
As long as they never buy from that website again, they can have it.
