Xbox One Version Available for Preload
October 10, 2014

Microsoft has revealed today that COD: AW for the Xbox One can now be pre-ordered and pre-downloaded ahead of the games release. Preloading the game, as the name suggests, downloads a majority of the game's files beforehand, which then allows you to jump straight into the action once the game is released.
As a friendly warning, if you are going to purchase the digital copy, start preloading the game as soon as possible - it clocks in at 45.84 GB. That would take nearly 3 days to download on a normal 2 Mbit connection.
