Raiden IV Confirmed for Xbox 360

1UP reports: For fans of oldschool shooters, Raiden should require no introduction whatsoever. As shoot-'em-ups go, it's among the more approachable series in what's a notoriously unapproachable genre for many -- with only a few types of weapon power-ups and a difficulty level that starts out simple and gets challenging on a nice, leisurely curve, it's a nice introduction to the genre as a whole. And Xbox 360 owners will have a chance to get acquainted very shortly -- Raiden IV developer Moss has announced a September 11 release date in Japan for the 360 port of their arcade shooter.
