Xbox One X pre-orders now open - with a sting in the tail

The One X is already sold out at several retailers

Pre-orders for the Xbox One X are now open through Microsoft, but you'll need to move fast to get one of the limited edition Project Scorpio versions.

Microsoft unveiled the Xbox One X Project Scorpio Edition during its Gamescom press conference on Sunday. Its only differences are cosmetic, with the limited edition device sporting 'Project Scorpio' branding on both the console and controller, alongside a new exterior pattern and a vertical stand.

The packaging is also slightly different, and Microsoft says it's 'inspired by the original Xbox.'

Microsoft is only making a small number of Project Scorpio Edition consoles, and they will only be available during the pre-order.

Microsoft also revealed more details about its standard Xbox One X console on Sunday and said that the 4K-capable machine will offer smooth gameplay at full Ultra HD resolution, while those with 1080p screens will see games run faster and smoother than before.

Designed to take on Sony's PS4 Pro, the console also packs 6 teraflops of graphical power, 1TB storage and 12GB GDDR5 RAM.

The Xbox One X will start shipping on 7 November priced at £449, and Microsoft says there will be 42 new titles launching along with it, 22 of which are exclusive to the console. These include Forza Motorsport 7, Super Lucky's Tale, and the console launch exclusive PlayerUnknown's Battlegrounds.

In addition, the Xbox One X will support all Xbox One games and accessories. Some new titles classified as 'Xbox One X Enhanced'will be able to utilise the new console's enhanced processing capabilities, but will also run on Microsoft's lesser-specced consoles.

Pre-orders for the console went live on Amazon on Sunday, but the console is already showing as sold out. Game still appears to have some Xbox One X consoles in stock, but you'd better act fast.
