EA's Origin Website is now offering a free copy of Battlefield 3 with preorders of Mass Effect 3, BioWare's upcoming action/RPG sequel. This seems to cover both the standard edition for all platforms and the PC-exclusive digital deluxe edition.
I wouldnt want another game in origin, I've got BF3 already on it. Never understood why they never placed it on steam, soon as I've finished playing BF3 origin is switched off.
