Well, honestly, the game deserved the hype! I even think that the hype wasn't big enough. If you thought that the level in the demo was beautifull well ... you've seen nothin! There are a lot of weapons and they're pretty funny to use. Boss are good, you don't need 30 minutes to kill them and that's a good thing IMO. There are many different kind of hellgasts, another good point!
The story is better than what I expected, with really nice cut-scenes and dialogues. One more thing: I've read in many reviews that every levels look almost the same ... well Hell no!
So get ready, cause you'll be killzowned!
Oh yeah: you have a lot of different objectives in one mission, so the game put you in front of new situations all the time, that's not like resistance 2 where it was: corridor-ennemies-corridor-ennemies...
