Xbox Series X and S owners will be able to apply a new Call of Duty: Modern Warfare 3 dynamic background in preparation for the game's imminent November 10 launch. Call of Duty: Modern Warfare 3's early access campaign launch, which began on November 2, has been causing a sort of uproar as many players are frustrated with its confusing Call of Duty HQ rollout. Add to that a mandatory full-screen ad for the game which appeared on all Xbox consoles, and sentiment surrounding Modern Warfare 3's launch has been less-than favorable so far.
