If you preordered your own copy of Final Fantasy XV via the Square Enix store, you can potentially be entered into a contest to win a custom Final Fantasy XV edition Xbox One meant to resemble Noctis’ weapon, the Engine Blade.
The Engine Blade itself is a sword with a motorcycle engine at its hilt, so it’s already a pretty interesting-looking weapon.
You could have an Xbox One to match it, if you’re lucky.
