Microsoft has been announcing new holiday Xbox One bundles this week, and the company is closing with the Xbox One Fallout 4 bundle. It will offer buyers the 1TB version of the console, along with free copies of both Fallout 4 and the Xbox 360 version of Fallout 3 for $399.
The Xbox 360 version of Fallout 3 will be able to be played on the Xbox One when the console adds backwards compatibility features in November. Also, mods for Fallout 4 that will be made by third-party creators for the PC version of the game will be able to be played on the Xbox One version sometime in early 2016.
The Xbox One Fallout 4 bundle is now available for pre-order on the Microsoft Store and other retailers for shipment on November 10
