If you bought DA2 on any system (pc, 360, or ps3) then you are entitled to a free copy of Mass Effect 2 (on pc)!
As I already have Mass Effect 2 on pc, I'm not sure why I need an extra copy but if any want a free copy of Mass Effect 2 on pc I'd be happy to give you my code...(I am not sure if it will work for others though?)
