The Xbox 360 version of Call of Duty: Ghosts will require an approximate 3GB installation for the single-player campaign, Activision has confirmed.
Players looking to take part only in the game's multiplayer component won't need to install anything, however.
Activision community manager Dan Amrich detailed the installation in a post on his blog, confirming that the installation would be small enough to play on Xbox 360s with 4GB of flash memory.
Users who need extra space can also format up to 32GB of a USB 2.0 stick to be Xbox 360 compatible.
Amrich also pointed out that the download for the preorder bonus map Free Fall clocks in around 250MB.
Call of Duty: Ghosts will launch on November 5.
