How do I get my pre-order bonus content?

The easiest way is to just plug it into the origin key box.

This is what I did, and it worked seamlessly.

This video shows how.

On the Xbox 360 version, you simply type your pre order code into the "Redeem a Code" section of your Xbox dashboard. This will redeem your pre order bonus and download into to your Xbox 360 console.

For PC you open up origin and go to the settings menu (indicated by a gear) then go down to 'Redeem Product Code', enter the code then download the content.

For Xbox press the guide button in the center of the controller, go to the very left and there should be a 'Redeem Code' option, select this then enter your code followed by a download of the content.

For PS3 go to PlayStation store and at the top right should be a 'Redeem Code' option (never would have guessed that would ya), enter the code followed by the download.

This will only work with unique codes that haven't been used before.
