Galaxian 3 is a game in the Galaga series.
Galaxian 3 was actually three games that were released for the Namco Theater6 arcade unit & the Japanese PlayStation. The games were all First Person Shooters where the player(s) would act as gunners on board a Galaxip called the Dragoon. Up to six players could act as gunners in 2 out of 3 of the games(The other game being four player). And the ending boss-fights in each were almost exactly alike.
