Back in June we reported that Electronic Arts was planning to team up with soft drink maker Dr Pepper to offer up free codes for downloadable content for EA games. Now our sister site Joystiq is reporting that the promotion has finally started with a free DLC code in every Dr Pepper drink.

The list of games that's involved in the promotion includes Spore, The Sims 3, Battlefield Heroes and the upcoming titles Mass Effect 2 and Battlefield Bad Company 2. You plug in your code at the Dr Pepper web site (after you buy your drink of course) and then you can select from a list of content, supported games and platforms which you can download for free.The promotion ends at the end of the year.
