As the title states, if you order ME3 through Origin you will receive BF3 for free. If you happen to have BF3 already you will be given a code that you can give to a friend. Just a friendly heads up.https://twitter.com/#!/origin_EA/sta...21583516794880https://twitter.com/#!/origin_EA/sta...48412470046721
This is actually a great deal, if you decide to sell the BF3 key then ME3 just paid for-itself!
