Even though the movie sucked, this game rocks.
Oh wait, there's a minimum amount of text, I guess I should use that as time to explain why it's so epic.
It's powered by Unreal Engine v3 and very successfully.
Presentation: It shows that it's the best movie based video game ever, even if the movie wasn't that great.
Graphics: Unreal Engine looks as awesome as ever. The real-time health regeneration is awesome and the claw marks left on foes is a nice touch.
Gameplay: Wolverine being violent, shed some blood, it's really fun. You will love to dismember and disembowel your foes.
Sound: I've honestly never heard better sound effects for slicing off limbs. And at least they use the voices of the movie actors.
Lasting Appeal: Play it once, and your done. But it's still fun as hell, you'll likely want to play over and over again.
