I took a look at Cinematech, G4's game cinema & footage show, and they were showing gameplay footage of Ninja Gaiden(first footage they showed, aired yesterday at 10:30p). Here's what was in it:
-In the beginning it showed a person who looks like Conan the barbarian sitting, and then stands up as Ryu approaches. The barbarian guy whips out a nunchuck and starts performing some wicked moves.
-Ryu has a move similar to Shinobi's tate combos where he flies/dashes to an enemy and cuts them down in a fraction of a second. Then the enemy would pause briefly and die. The only difference was that you didn't need the 5+ enemy requirement and there was no dramatic scene, Ryu just did it.
-You do fight against ninjas. It only showed two types: one wearing a brown outfit and the other wearing white.
-The stages are various from what I can see. At first it shows Ryu fighting in a huge library. He sees a crack in the wall. Goes to the menu screen, selects a throwing dagger, and throws it at the wall. The dagger explodes creating another route.
-Another scene shows him running around what looks like a European setting. Nothing much.
-A scene also shows him reaching upper areas with multiple wall jumps. He also clings to walls(it only showed him doing it for a second though), and was running along walls.
-The last scene shows him entering "Ninja Fortress". Inside there's a puzzle. A samurai statue is missing a face piece. He finds it and gets a key. The demo ends.
-Remember the trailer from this years E3? Where that red female demon comes through a glass window? There's a brief clip showing Ryu there fighting a bunch of demons. Same as the purple one you see in various videos, but their color is brown.
-Remember the trailer from last years E3? Where a bunch of ninjas are surrounding Ryu in a small room? It show some of that too. Nice lighting from the windows. At one point he cast a fireball spell and a ninja dodges it.
Well, that's it. I was mainly posting this for Mottzilla, just in case he couldn't see it.
