If you thought Mortal Kombat was all about the same ol' same ol', you thought wrong.

While it's true that NetherRealm is seeking to cater to the ardent long-time fans who wish to see a resurrection of all that made MK great, the team has implemented something quite new- the Challenge Tower. They talk about it in the video shown here; this mode features no less than 300 missions, all of which are designed to test your knowledge of the character(s) and the game's mechanics.
