The option to use a custom image on your Xbox One background has been available for quite some time, but now that the New Xbox One Experience is out, you might find its time to update your existing background. So Major Nelson has asked the Xbox design team to create a Photoshop .psd template so you can easily create your own great looking custom made backgrounds for your Xbox One.
Thankyou Sir Nelson
You can download the .PSD here (7 MB Zip File)
