Summary: It's the EXACT same game as MK: Deception, but broken. Load times are WAY too long, and the controls are not as responsive as they should. Good game because it is a portable version of a great game, but I wouldn't call this a must have.
Excerpt: Mortal Kombat: Unchained is almost a direct port of the very good PS2 title Mortal Kombat: Deception, I say almost because in MK Unchained there are a few extra characters that have come across from Deadly Alliance and there is also the addition of the Endurance mode (more on that in a moment) It offers the things you would expect from an MK game; blood by the bucket load, memorable characters and good all round fun.
Pros: Good list of characters, short loading times
Cons: Graphics may be a little fuzzy in puzzle mode
