Gunvalkyrie

Gunvalkyrie is an alternate history/science fiction video game developed by Smilebit and published by Sega for the Microsoft Xbox.

Originally developed for the Sega Dreamcast, its visual style was very similar to the final Xbox version. The Dreamcast version's distinguishing feature was that during the game's development, GunValkyrie utilized a unique control scheme using both a light gun and a controller. This control scheme was dropped when development shifted to the Xbox version.
