Yeah, the final dimension in Spider-Man: Shattered Dimensions is Ultimate Spider-Man. Only there's a twist, he's wearing the Venom Symbiote. For those who don't know, Ultimate Spider-Man was a separate comic line, remaking Spider-Man's origins in a new universe without the bounds of all those years of continuity. Apart from that, it's more or less the same as Amazing Spider-Man. I mean, he doesn't have any new powers, he's just a teenager, which is why I suspect they added the symbiote.
Thing is with the symbiote, in Ultimate continuity, the Venom Symbiote turns whoever wears it into a monster who eats people. Spider-Man wore it on only two occasions, the first of which was very short, and the second of which was ended prematurely when the Ultimates came to kick his ass because he was eating people. Point is, they had better have a very good reason why he's wearing the suit and why he's not devouring civilians.
In a way, I feel like this is a cop-out. The other two dimensions were things never seen in a Spider-Man game before. Noir, with it's 30's style and stealth-based gameplay, and 2099, with it's incredibly tall buildings you can actually jump off of, are completely new to video games. There's already been an Ultimate Spider-Man game, where you could play as both Spider-Man and Venom. Spider-Man was the same as ever, and Venom was a giant brute who attacked with symbiote tendrils and ate people. Any area not covered there I'm sure has been done in Web of Shadows, where there were two suits to use, and the black suit was primarily concerned with killing everything with giant tentacles and other more brutal stuff.
The point I'm trying to make is that I've done this all before as far as Ultimate is concerned. I've swung through the cel-shaded streets, I've killed stuff with black tentacles of death. I was expecting something really left-field or obscure for the last dimension, since they kept it under wraps for so long. Something like Spider-Carnage or Zombie Spider-Man. I suppose it's better than Amazing Spider-Man with a symbiote suit. I'll have to see how further previews go before I'm able to make another judgement.
