I saw this up there on Thursday and downloaded it. I have been eagerly awaiting this game and so far it looks great. The demo is short (not as short as Heavenly Sword), but absolutely worth it. You get to use either of the two main characters in a little "how to play" type single level with a boss. It appears to be done with the same engine as
Genjiays of the Blade and that is a good thing as the graphics for that were very good. Game play is fairly simple, 4 "power" buttons to which you can assign various attacks or defenses. You acquire different powers by absorbing them from defeated foes in various ways, depending on the enemy. The graphics are impressive, as expected. The sound was a bit of a surprise too, it gives you a big, open feel with the surrounds providing directional ambient sound pretty much all of the time. Give it a look!
