Here's the first ten minutes of Cave's bullet Hell shooter called Dodonpachi Dai Fukkatsu Ver 1.5. Released on the 360 in Japan on November 25th this is the 5th in the Dodonpachi series. This title is region encoded so it will not work on anything other than a Japanese 360. If you don't have a Japanese 360 you could always try your hand at the iPhone version which is called "DoDonPachi Resurrection".
