The third game in Namco's classic Galaxian series, Gaplus picks up where 1981's Galaga left off. While maintaining the same classic 'look' of its predecessor, Gaplus's graphics are a definite improvement over those of Galaga; the game's increased color palette and subtle use of shading making the attacking aliens look rather more solid.
Another enhancement over its prequel is in the addition of a player-acquired 'Tractor Beam'. In Galaga, only the enemies had access to the beam; enabling them to capture one of the player's 'Fighter' ships (the player then had to shoot the captor to release the Fighter). For the sequel, however, the player can now acquire the Tractor Beam. This is achieved by shooting one of the alien formation's 'generals' - a visibly more colourful alien than its comrades. The Tractor Beam will then activate for a limited time and any aliens the players captures (up to a maximum of six) will dock alongside the player's ship for enhanced firepower.
One final yet important addition is in the movement of the player's ship. In previous installments, the ship could only move left and right along the bottom of the screen; in Gaplus, however, the ship can now move UP the screen - although only to the halfway point. This is important as the alien's aggressive attack patterns will often see enemy craft swirling around the bottom of the play area.
As with Galaga, Gaplus features regular 'Challenging Stages', with benign aliens swooping across the screen for the player to shoot as many times as possible, in order to try and spell out a word and earn extra bonus points.

Gaplus machines came in an upright dedicated cabinet that was similar in appearance to the cabinet used on the original "Galaga". These machines were black and were decorated with multi-color stripes, and sticker sideart with a realistically drawn scene from the game. There were several different marquees made. The American Gaplus marquee had a blue 'Gaplus' logo surrounded by a scary looking bee. The 'World' version had a green 'Gaplus' logo. Finally, many machines in the USA will be labeled "Galaga 3" on the marquee, but will have 'Gaplus' sideart and ROM chips (lots of lazy operators who didn't bother to install the whole name change kit, made these common). All machines are decorated with red T molding. The control panel has a single 8-way joystick mounted in the center, with 'Fire' buttons on either side. This panel was not decorated at all, it was simply black. The monitor bezel had a few game instructions on it, but was not overly decorated either. The game itself was displayed on a 19" Electrohome open frame monitor that was mounted vertically. This title uses the same wiring harness as "Galaga", and the two titles can be interchanged very easily. Many other games (such as "Dig Dug") use this same harness as well.
