Oh WoW!!! I've just played the PS3 version and i must say i like it. I never liked the Ninja Gaiden games before. I felt they were too hard for me. I just like having fun in games. Well it's still hard. A lot of bad guys that just attack you, i mean what's up with that, bad guys attacking you what's that about lol. But seriously the spells are cool when using them. I like it when i do something cool and i have no idea how i did it. lol Oh yeah, there is blood in it, it just doesn't spray that much i think. I really wasn't paying attention but your sword and stuff gets covered in blood and the ground gets blood on it too. It's just the limbs disappear once they are cut off. Actually i thought it looked cool with that mist that comes out. I don't care much for blood and guts. If killing can be pretty then bring it on lol.
You get to play as Ayane in the Demo and she is fun to play as. Oh and the Sixaxis works in the demo her boobs did jiggle lol.
Even though i liked it i probably won't get it. I mean they unlocked all the weapons and put them on level 3 for you so obviously i can't play the real game this way. (I miss cheating lol)
Oh also there are Team missions. I haven't tried that yet. I don't do teams I work alone lol.
Just so you know it's up on the Japanese store and not US or EU but it's in full English. That really suprised me, i didn't expect it.
