Electronic Arts will unleash their pre-order campaign for the upcoming title, The Simpsons Game. Four of the biggest game retailers (GameStop, Wal-Mart, Target and Best Buy) will each have an exclusive, limited edition The Simpsons Game Parody Poster for early customers. Each Poster is representative of an in-game parody featured in the new title. In addition, each retailer will have a specifically created cheat code printed on the back of the game posters to open some of the unlockable content in the game. These are all while supplies last.
