[The Nun Eater]

It has one of the most interesting stories of any fighting game I have ever player. It provides background for all the classic MK characters and does a decent job of keeping you interested enough to finish the lengthy campaign. As far as the fighting goes, it feel just the same as Mortal Kombat 3 so it familiar but with slight changes.

It's fun to play if you enjoyed the old ones. Not to mention they ramped the violence up to 11 and thats never really a bad thing.
