It looks like if you pre-order a copy of Mass Effect 3 at Origin, you’ll also get a free code for a copy of Battlefield 3.

Origin emailed me about this deal and they only mentioned the N7 Collector’s Edition. However, on the page for the deal it only says pre-order BF3 is a requirement. It doesn’t mention CE at all in the small print. Note that if you already own a copy of BF3, you don’t qualify for the deal.

VALID ONLY ON NEW PURCHASES OF MASS EFFECT 3 (“PRODUCT”) FROM THE ORIGIN STORE AT WWW.ORIGIN.COM AND ONLY FOR THOSE WHO DO NOT CURRENTLY HAVE A DIGITAL VERSION OF BATTLEFIELD 3 (“BF3″).
