Dan Amrich, Community Manager for Activision has blogged some install tips for Call Of Duty Ghosts on Xbox 360. Dan blogs that the 3GB install is only required for the single player campaign , and that if you want to jump right into the multiplayer action the only download is for the dynamic MP map Free Fall (a bonus with preorders) which is less than 250MB. Not long now guys and we can start ranking up on the special launch double XP weekend !
