I ended up getting the game at midnight and it is really sweet so far. So far I have done Liu Kang's Fatality, Sonya Blade's fatality, Nightwolf's pit fatality and Kratos' Babality.
The challenge tower is difficult at times but really cool overall. It reminds me of the Tower of Lost Souls on Soul Calibur 4. Only you are given certain tasks to complete. I.E. with the characters Johnny Cage and Stryker, you have to use Cage's fire ball and Stryker's pistol to hold of a horde of the undead where if they touch you at all, you have to re-start it. The new test your might, sight, and strike add substance and more playability to this game. For any fan of Mortal Kombat, I think the new game is a must buy. Overall 3.5/5 Stars.
