I just did this earlier today. You have the pre-order from Gamestop right? Well, you need to go to MassEffect.com, and click on the "Redeem Code" link, like the paper tells you to. Now, you'll need to sign up for them, or if you have an EA online account you can link it to. Sign in, or sign up. If you have XBOX, you need to have the Cerberus network registered, with that little card that came in the case(I think. Mine did). Restart your console and at the main menu, the option to download the armor should be available. Then, just chose it in the armor customization menu.
