I don't know. It seems like it's just too gratuitous. It makes me wonder if they're trying to cover up a mediocre game with flashy powers and gore. I'll wait to see the consensus before I'd consider buying it.
It looks like you're practically indestructible throughout the whole game. If you have all of your powers from the beginning, what do you have to look forward/build up to?
It reminds me of the build up to Assassin's Creed, which I thought was a decidedly mediocre, therefore disappointing, game.
