With both game and album debuting on November 5, Activision and Aftermath/Interscope Records have joined forces to offer a discount on Eminem's upcoming album The Marshall Mathers LP 2 to anyone who pre-orders Call of Duty: Ghosts.

From now until launch, those who pre-order Call of Duty: Ghosts from GameStop will find a code on their receipt when they come in to pick up the game. This code entitles buyers to download a special version of The Marshall Mathers LP 2 which features "an exclusive, bonus studio track" for $9.

Furthering this joint marketing effort is an upcoming trailer for Call of Duty: Ghosts, which will feature "Survival," a track from The Marshall Mathers LP 2. "The energy and intensity of 'Survival' really matches Call of Duty: Ghosts," said the musician. "I'm excited to continue to be a part of the franchise."

As we reported earlier, according to Gamestop, Call of Duty: Ghosts is currently on track to be the most pre-ordered game of 2013.
