Gaplus was released by Bally/Midway, under license by Namco, in July 1984 in the USA, even though the in-game title screen makes no mention of Midway and lists Namco as the manufacturer, probably because the game was released after Namco and Midway parted company. However, the Bally/Midway name does show up on both the marquee and the promotional flyer.

A conversion kit was released in the USA about three months later, changing the game's title to "Galaga 3". The game is known outside the USA exclusively as Gaplus.
