Galaxian is a shoot 'em up in which the player is at the bottom of the screen, with an arrangement of aliens at the top. The player moves left and right to aim at an alien, then shoots a bullet up the screen, and the alien it hits is killed. The aliens are classed as Drones, Emissaries, Hornets and Commanders, with those higher up the screen scoring more points when destroyed. At set intervals an enemy will move down the screen towards you, escorting a bomber, which is a moment of high danger. Clear a wave and another is generated.

1001 Video Games

The Arcade version of Galaxian appears in the book 1001 Video Games You Must Play Before You Die by General Editor Tony Mott.


Atari 2600 programmer Mark Ackerman, at the time working in Atari's "think-tank" GCC, was granted a patent for his technique invented for the 2600 port of Galaxian, allowing eight sprites to be displayed in one row.


Atari's 2600 release of Galaxian came with the comic book Atari Force #5. Here is that comic at


Galaxian (and its clone, Cosmic Crusader) get away with relatively high framerates on the original 4.77MHz PC because they don't use the entire screen for a playfield; the right fifth of the screen (64 pixels) is unused. Another side-effect of shortening the playfield to a width of 256 pixels is the optimization of game calculations, stemming from the fact that horizontal coordinates fit in a single byte instead of two.


Was later re-released under the Thunder Mountain label. What makes this trivia? Usually only Mindscape games were released under Thunder Mountain... Galaxian was originally licensed to Atari.
