Though the Origin Website lists a number of perks for preordering Battlefield 3 through Electronic Arts' online service, an unannounced bonus is also available for this advance commandment to the military shooter sequel, according to Ars Technica. They report "a friend" who preordered the game tells them he received a code from EA for a free copy of either Mass Effect 2, Dead Space 2 or Medal of Honor, and that this offer is only valid through the end of August. Update: Several of our readers have confirmed receiving this offer as well.
