Via Neogaf are aware of how much space you'll need on the Xbox hard disk One to install three of the flagship titles for the new console. Ryse: Son of Rome will occupy 47 GB, while 5 Force and Dead Rising 3 instead will require both 35 GB. This was discovered through the images of the back of the covers of the games in question, which we show you below. Please note that all games Xbox One will be completely installed on the hard disk, but you can now start playing them even during installation.
