The demo was utter garbage and it is just yet another in a long list shooters that are no longer being innovative. I have just about given up on all shooters because the theme is the same over and over again. It looked and played like UT on rails.
This game is the most innovative shooter for a long time - really, you should give it a try! It's just that you can play it as a run'n'shoot-game - which is boring - or as the kill-with-skill-game, that way it's a really new feeling. Try it!
