Turns out the offer expired overnight(in my case cuz he told me about it yesturday) Sorry =(
My friend told me that he got Fallout 1 for free.
Wanting to try it i asked him where he got it, and he told me about gog where they're right now giving it for free!
I don't know much about gog other than its a place to buy older games for cheap.
