Some company called New World Systems is porting Raiden Fighters to Xbox. What's Raiden Fighters? A 6-year old top-down Japanese arcade shooter.
I couldn't find screenshots of the one they're porting but
KLOV has shots of the sequels: Raiden Fighters 2: Operation Hell Dive and Raiden Fighters Jet.
The game should be out by the end of the year... in Japan. I'm not sure if they'll do what Sony did with Raiden Project back in 95 (a launch title that had Raiden and Raiden 2 and a 3-D intro) or if it is just a port of the original. The Raiden series was always VERY good, even the Jaguar Raiden was pretty good, so I'm up for it.
NCS said they'll stock it once it comes out.
