Some promotional thing from Dr Pepper on Destructoid.
Basically, you register a fake account with Dr. Pepper, enter in a code, then go log in with EA, then log in again with Bioware. Once you do all that, you can get one of three promotional pieces of headgear.
You can get all three if you make a new Dr. Pepper account (which is easy since they don't verify your info). It's just up to you whether or not you want to spend the time to get a helmet that gives you +5% in either power damage, weapon damage, or shields.
