Published by Namco in Japan and Midway in North America, Galaga is the sequel to the 1979 game Galaxian and like its forebear is a shoot ‘em up game in the vein of Taito’s Space Invaders but with unique gameplay features that make it a distinct and separate experience.
One of the most revered titles of the “golden age” of arcades back in the 1980s, Galaga has ports to almost every classic and modern console with its most recent Galaga 30th Collection for iOS.
Galaga Gameplay
With a simple objective – score as many points as possible by destroying insectoid like ships – Galaga attacks the player in formation waves, suicide strikes, and every other kind of way possible to take out your starship. Like most games in this genre, Galaga works on a lives system meaning once you’ve run out of “lives” or “ships,” it’s game over.
Unlike Galaxian, Galaga allows the player to fire two shots, either in rapid succession or one trailing after the other. Not only does this heavily modify the strategies players use to avoid getting their spacecraft destroyed but also helps tackle the more complex patterns the enemies in Galaga throw at you. Further, Galaga adds in “challenge” stages every few rounds to award players with bonus points, a feature not found in Galaxian.

Sporting bright colors and detailed sprites, Galaga also took Galaxian’s graphics to the next level. Modernized and remade more times than we care to catalogue, Galaga, like Taito’s Space Invaders and Nintendo’s Donkey Kong, captures a very specific moment in the video game industry’s zeitgeist.
A raving commercial success, Galaga’s ability to take concepts introduced in other games including its forebear Galaxian is a testament to the ability of companies to innovate while being derivative.
