It's okay...
I can't believe that this game was ever $50 when it first came out. The graphics, soundplay, sound, etc... just were not as good as it really could have been.
It's supposed to be X-men 2, but the story is way far away from the movie. I don't know why it's like this. One nice thing though is that you get to fight a bunch of Wolverine's enemies. There's also a special attack sequence, where you press certain buttons and watch as Wolverine executes a cool KO to whomever is around the corner.
Do not buy this game, unless you absolutely must have it, because it's not really worth what you'll pay. Unless you're paying ten bucks. Overall, the game wasn't as good as it could've been, and it should have been better scripted.
PS. They didn't even use Hugh Jackman's voice as Wolverine.
