Gaplus

Gaplus is a fixed shooter arcade game that was released by Namco in 1984. It is the third title in the Galaxian series and was only known by its original name in Japan. When Midway Games released it in the United States, the name was changed to Galaga 3, possibly to increase recognition among fans of the series and boost sales. The bonus stages were also very different - they involved firing at the enemies and keeping them in the air in order to spell out words. In order, these were "BONUS", "GAPLUS" (even in the US version), "DOUBLE", "TRIPLE", "GOOD!!", "LUCKY", "BYEBYE" and "EXTEND".
