The image is nice homage both to the character that helped propel the Xbox to success and to the One X's code name, Project Scorpio. Meanwhile, in the Halo games themselves, the tanks the Master Chief uses are also dubbed Scorpions.
The Xbox One X has an engraving of Halo's Master Chief riding a scorpion inside the console. You can see it here, just after the 11-minute mark. To check this doodle you have to break open your Xbox One X - the choice is yours.
The image holds multiple meanings in relation to the Xbox One console.
Of course, this isn't the first time Microsoft has hidden the Chief inside its Xbox hardware. If you're really attached to the console's old codename, there's even a 1TB Project Scorpio edition of the Xbox One X available for preorder. A comfortable way that will allow Xbox Insiders to download all 4K assets in advance, getting ready to play on Xbox One X all titles now supported.
