I bought this based on the reviews of others. I assumed that it would be the game version of the recent Movie. While some of the story line is similar, for the most part it is a completely separate storyline.
The game focuses in two main time frames, when he was grafted with the Adamantium, and three years previously in the operation in Africa.
As you progress through the game you gain more abilities that can be used on your "victims" (enemies), these range from shredding people to decapitation. I even managed to cut the legs off an enemy. When Wolverine is injured by fire, bullets, knives, or impaled on an object, it is great to see the wounds healing. You can also use Feral senses which allow you to see things you normally wouldn't see.
You fight a few different bosses, most of which are the same basic character so easy enough to defeat.
The best missions for me were
The Helicopter missions - Diving from Helicopter to Helicopter ripping them apart.
The Sentinel mission - Fighting a 200 foot Sentinel. (before that mission it was creepy walking past it each time)
Fighting the Blob in the Supermarket - It's almost like a rodeo.
The last African mission - You pretty much fly through it.
Fighting Gambit - By far one of the hardest bosses to defeat.
I was a small bit disappointed with the ending, but overall it was a great game. Truly enjoyable.
