Pretty good, and lasts a while, but does get boring every now and then.
Overview:
Graphics: Ok, nothing special here though. The cut scene graphics look a little glossy and watery, but are a bit better.
Gameplay: Nice stunts that are easy to pull off, but the levels will seem very similar, and fighting demon after demon, it all becomes the same after level 4
Sound: Ok music, voice actings ok, and good enough sound effects
Storyline: Not much here, there are only a few characters in the game, mainly because demons have taken over the world. The setting is in a japanese demon infested city, and the main character must fight his way past armies of demons, and demonic generals to take out the leader.
Obviously this game doesn't have much to it, it's one of those you're going to want to sell right after you beat, as the replay value is very low here. You may want to rent this before you play it.
