Yesterday, Major Nelson announced on his blog that Mortal Kombat X is available for pre-order and pre-download on Xbox One. Mortal Kombat X will be released next month, on April 4, and before that you can pre-order it through Xbox Store.
Though, you won’t be able to play it until 12am EST on the release date, but after you buy it, you can pre-download it in order to be ready to play when the time comes. To download it, you have to select Manage button on your console, on details page.
The PC and PlayStation 4 versions of Mortal Kombat X will be released the same day as the Xbox One version, while the PlayStation 3 and Xbox 360 owners will have to wait a bit more, as those editions will launch in the summer.
