Luckily the screen tearing will get fixed soon on the xbox.

I downloaded the demo for Beyonetta but have not played it yet. I watched a few videos for that game but I'm not impressed with the art style, just not what I like.
I think the Darksiders art style is really why I absolutely love that game but I will play the Beyonetta demo and see what I think.
