Bangai-O

angai-O, known as Bakuretsu Muteki Bangaioh (爆裂無敵 バンガイオー) in Japan, is a shoot-'em-up video game developed by Treasure for Japanese Nintendo 64 consoles in September 1999. With assistance from Conspiracy Entertainment it was brought to the Sega Dreamcast three months later, where it eventually saw a worldwide release.

There is also a Collector's Edition of the game that was given out as part of a contest in Japan. Only five copies were ever made making it extremely rare.

The European version was published by Swing! Entertainment, but it was however released under Virgin Interactive, the European distributor of the game's T-Series code.
