i got the demo earlier today, was one of the last before microsoft closed other regions. I gotta say this game is awesome. It is the same ninja gaiden game as before, so if you didnt like the old one you wont like this one. Its literally the same. New moves, new weapons, new gore/finishers but otherwise the same.
It only lets you play on easy (path of the acolyte) but the enemies are still ruthless and attack alot, and they still try to kamikaze your ass plenty. I can tell that this is still gonna be the frustratingly hard game as before but i love it. The camera, the linearity, the moves are all in ninja gaiden fashion. I would probably call this a NG1.5 but its still awesome.
Cant wait till the 3rd!
