If anyone bought a copy of Darksiders and found a promo code inside the box and didn’t know what it was for, then all has now been revealed.
It gives you access to lots of digital artwork etc for Darksiders and the best part, you also get a FREE COPY of Red Faction Guerilla, for either 360 or PS3.
Sooooooooo if nobody wants their copy of Red Faction on PS3 then i will be glad to take it off your hands
