*All the female characters have the exact same body type, and their primary outfits are far too slutty. At least there's alternate costumes to fix this annoyance.
*Challenge Tower is way too repetitive, and sometimes cheap.
*The reward for completing the 300th Challenge. Seriously?
*Kabal spamming. Reminds me way too much of the Flash.
*The dialogue is incredibly cheesy.
*Liu Kang sucks big time in this game.
*Noob is terrible.
*Cyber Sub-Zero was unnecessary, and is a waste of space.
*The Krypt navigation is too stiff.
*I haven't played online yet, because I'm getting Internet hooked up in my room on the barracks next week. But, if you're releasing a game and hyping its online value, then you better insure that you justify your hype.
