No, you fight victor before you fight deadpool and he's not there to support you. Just one on one with the pool, who is a cunt to beat.
Speaking of the ending, I won't spoil anything, but the scope of the ending is much much bigger than anything put forth by the movie. If FOX's gaming division has any brains, they will commission Raven to make a sequel based on what this ending has to say. And they better not wait till the next movie is out. I don't see why we couldn't have another kick-ass Wolverine game before the another Xmen film hits the theatres. Just get Raven to do it.
Overall, this game was a big surprise. Big thumbs up to Raven for not only getting a "Wolverine" game right, but also making a Movie tie-in game better than the actual movie.
Alex, you going to be reviewing this?
