To celebrate the home release of Marvel's Black Panther -- available now on digital and May 15 on Blu-Ray -- Microsoft is giving away a custom Black Panther Xbox One X, alongside a 4K copy of the film. You can enter the sweepstakes right now, but be aware that there only five units up for grabs. In the event you defy the odds and come up a winner, you can expect a machine adorned with the likeness of both Black Panther and Killmonger, as well as matching controllers dedicated to each character. The sweepstakes will be open until May 29 and are only available to U.S. residents. Go here to enter.
