it was exact same as ufc undisputed '09, but with like 5 more characters. it was pretty lame compared to what the demo set the game up to be. i would only suggest this game if u want a up-to-date version of ufc '09.
If you've played the first one, you've played this one. The differences are mostly aesthetic, and online play isn't available unless you buy a code. The combat improvements were so minor I can't even remember what they were as I type this. There are a couple new single player modes, but they're nothing special. What I want to know is: Why am I still unable to take my favorite fighters through a career?
