Rockstar Games has confirmed an exclusive deal with GameStop to offer exclusive in-game content for consumers who pre-order Red Dead Redemption on the Xbox 360 or the PlayStation 3.

"We're privileged to have fans that are just as passionate about our games as we are," said Alex Moulle-Berteaux, head of marketing for Rockstar Games. "Having fans choose their own pre-order bonus is a unique way to let them be a part of Red Dead Redemption."

Players can vote to choose an outfit that will be earned by completing a unique set of in-game challenges. Once the challenges are completed and the outfit is unlocked, the outfit will uniquely affect how the surrounding world responds to the game's protagonist, John Marston. Stay tuned throughout the month of January for new information about the outfits and their effects in-game.
