Mortal Kombat vs DC Universe has just been added to Xbox Live's Games On Demand service which allows you to download games directly to your Xbox 360 HDD.

This is the first Mortal Kombat game to become available through this service.

You can purchase the game directly from your Xbox 360 Console at the price of $29.99. It is also available for download outside of the United States.

This could also potentially spell the possibility that previous and upcoming Mortal Kombat games can be bought from Xbox Live in the future!
