Galaga '91 (ギャラガ’91) is a sequel to Namco's 1981 arcade classic, Galaga (brought to the SG-1000 as Sega-Galaga). It is actually a port of Galaga '88, originally released in arcades in 1988, retitled to reflect its Sega Game Gear release of 1991. It is the first portable installment in the Galaxian series.

Galaga '88/'91 builds on the gameplay seen in Galaxian, Galaga and Gaplus, the most notable addition being the inclusion of more detailed backgrounds (as opposed to coloured scrolling starfields). The Game Gear version was not released in North America.


An intergalactic organization, the United Galaxy Space Force, deploys a lone starfighter to rid the galaxy of the hostile Galaga aliens, who plan to eradicate all of mankind.

Bonus stage

Galaga '91 is a fixed shooter video game. The player controls a lone starfighter throughout eleven different stages, each becoming progressively difficult. Stages are indicated by small emblems located at the bottom-right of the screen. In each stage, the objective is to destroy all of the Galaga aliens, which fly into formation from the top and sides of the screen. Some enemies fire projectiles at the player, some enemies divebomb towards the player and attempt to collide with their ship, and some enemies spawn other enemies.

The player can move the ship horizontally with Left and Right but cannot move vertically. The 1 button fires; it can be held to fire continually.

Most stages are fixed and do not scroll. Enemies enter in formation, and all enemies must be destroyed to complete the stage. Some enemies screen-wrap to the top of the screen when they reach the bottom.

Stages 3, 8, and 12 are bonus levels, which are indicated by the text "That Is Galactic Dancing." In these, enemies fly into the screen along pre-set paths without attacking the player. Players can shoot down the aliens to earn bonus points; destroying all enemies awards the player a large sum of points.

Stages 4, 13, and 14 are vertically scrolling. Enemies fly in as before, but it is not necessary to destroy all of them to proceed. The screen continuously scrolls upwards until the end, where there is a boss fight.

Galaga '91 can cause confusion not just because of its arcade origins three years prior, but because in Europe, this Game Gear version was retitled (again) as Galaga 2, being marketed as a direct sequel to Galaga. It is, however, the fourth game in the series; being preceeded by the 1979 arcade game, Galaxian, Galaga in 1981 and finally Gaplus in 1984 (sometimes called Galaga 3 - an equally misleading title). To make matters worse, Namco released an arcade sequel called Galaxian³ (also known as Galaxian 3') in 1990, and the TurboGrafx-16 port of Galaga '88/'91 is called Galaga '90. More recent games have opted to avoid numbering systems and always use the Galaga name.
