The main difference being that Snakes on a Plane sucks ass. Just like Mario Sunshine, and I base that both on my own personal experience with the game and about 5 of my friends' opinions.
As for this game, I wish they would use this kind of formula more often. Most of the time all they do with a sequel is start you off in a different place with new weapons, and it's the exact same game. TOD seems to mix it up a lot more than most games do and it does it without sacrificing what made it cool in the first place.
I totally want this game. Number 1 on my list. I just hope the weapon effects linger while you pull out a different weapon, that way I can suck up a bunch of enemies with a guided tornado gun shot and then shoot the living crap out of them with something else while they're stuck in it. Think F4 twister with touch sensitive fusion grenades blowing around inside it.
