Mortal Kombat (commonly abbreviated MK) is a popular series of fighting games created by Midway, which in turn spawned a number of related media. It is especially noted for its digitized sprites (which differentiated it from its contemporaries' hand-drawn sprites), and its mix of bloody and brutal action; its graphic Fatality killing moves contributed to the founding of the ESRB.
