Sure, it's mostly the same game with the cover fighting, but the pacing of this game is 20 times faster than the last. You'll be deep underground one moment, in a worm, in a haunted mansion-like place, up a snowy mountain, and then fighting a water monster back underground in not a lot of time. There is so much variety that some of it seems tossed in, not very hard, and more than a bit unnecessary, but it does help the game fly along.
