Space Invaders is a arcade game released in 1978 and designed by Tomohiro Nishikado. Originally sold and manufactured by Taito in Japan. In North America it was licensed by Midway. Space Invaders is one of the earliest shooters and has spawned several sequels and remakes.


The plot of the game is simple. Aliens are invading Earth and it is your job to defend your home planet from the 3 types of descending Invaders before they destroy you or touch the ground.


In Space Invaders you control the Core Cannon, which moves horizontally across the screen firing at aliens. The aim is to shoot all of the aliens in 5 rows of 11. They move back and forth and every time they complete and get back to where they started they move down one row. Their goal is to reach the ground (Earth) and invade, for which then the player loses.



  • Originally, the invaders where meant to be soldiers. But they where changed to aliens to avoid any controversies.
  • Although you are trying to defend Earth, in the original 1978 arcade game with the colored background the planet appears to look more like the moon/Mars.
