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.
