Ghosts will require a little space and time to install its single-player campaign data. This should be less than 3GB of space, but you’ll want to make sure you’ve either cleared space or you’ve got an appropriate USB flash drive ready.
Ghosts will play on an Xbox 360 with an internal 4GB flash drive. Also, any compatible USB 2.0 flash drive (formatted for Xbox) with enough free space will work, including thumb drives. If you’re not sure if your thumb drive will work or how to format it for use with your Xbox 360, simply follow these instructions.
If you’re just planning to head to the multiplayer lobbies first thing, you won’t need to install anything – you can jump in right away, and soak up that special launch weekend of double XP.
Also, remember that the dynamic MP map Free Fall (a bonus with preorders) is an additional download, so you’ll need a little room for that too. That should be less than 250MB.
Nothing earth-shattering, but I figured you’d want to be fully prepared for the Ghosts launch. Not long now!
