Check out the awesome costume Battlefield 3 online pass owners will get free for Mass Effect 3. I believe this is for the online multiplayer. Very cool bonus. Thank you EA!

“When Mass Effect 3 launches on March 6 (9 in EU), Battlefield 3 players who’ve activated their BF3 online pass will automatically have access to an exclusive human soldier kit, inspired by Battlefield 3’s awesome aesthetic. The kit will automatically be granted when you sign into the Mass Effect multiplayer using the same Origin account linked to your BF3 Online Pass.”
