Gaplusaka Galaga 3 (1984 Namco licensed Bally Midway) Vertical Screen.
Gaplus is an excellent sequel to Namco's classic Galaga. The gameis very similar to galaga (a space invaders type shooting game) but it's muchfaster and has several new twists. The new features include the ability tocapture several enemy ships and turn them into fire power boosting drones.Several other powerups have also been added and the revamped bonus wave nowfeatures a rather cool twist in that you have to keep shot enemies in the air aslong as possible by firing at them repeatedly.
