Marvel's Wolverine developers say violence is an integral part of the game, except you will be able to turn it off anyway if you fancy.
Speaking with IGN, game director Mike Daly explains: "From the inception of the project, we knew that the number one most important thing was to bring the Wolverine fantasy to life. Not just that, but make it the ultimate Wolverine fantasy." He adds, "it was clear that violence was a key part of that." Because yes, while Insomniac's take on Spider-Man does have a bit of blood here and there, the footage we've seen of Wolverine features waves of gore and chunks of people flying all around the screen constantly.
