1UP.com has published their review of Mortal Kombat: Deception. They give it a 80%. Here is what they liked about the Konquest mode.
On the 'best' side, it shows just how far the light-hearted story and unlockable extras have come since the series began. To complete the mode and find everything should take non-FAQ reading players the better part of a year, and along the way is a fleshed out story that builds mountains on top of the back stories players have seen in past games, incorporating the campy storyline all the way through with some of the funniest bad voice acting around.
