Gaplus is a 1984 fixed shooter arcade game developed and released by Namco. It is the third game in the Galaxian series, serving as a direct sequel to Galaga (1981). In North America a modification kit was later released to change the name to Galaga 3, possibly to increase recognition, even though there was no "Galaga 2". It was the only other game to run on Namco Phozon hardware. A contemporary home port for the Commodore 64 was released in 1988. A Nintendo Entertainment System port of the game was created and included in Namco Museum Archives Vol. 2 as a bonus title.
