The lost city of Atlantis is under attack! Wave after wave of Gorgon vessels are approaching, each armed with weapons capable of destroying a part of the city. You are in charge of the command posts at the edges of the city and need to defend it from the invaders. The various gorgon craft will keep flying by on the screen in varying numbers and in different flight patterns. At first they fly high in the sky but then progressively lower. If an enemy makes it low enough before you destroy it, it will use it's weapons and destroy one of the buildings in Atlantis. As you progress in the game, the enemy craft will keep increasing in speed. The game ends when all remaining buildings in the city have been destroyed.

Atari 2600 version

The Atari 2600 version came with two possible box and four possible cartridge covers. One box cover was a night time battle scene. The cartridge for this would have been a foil cover with the same picture. The other box cover was a daylight battle scene. The cartridges for this were either a foil cover with the same scene, a foil cover with no picture, just text or a blue cover with no picture, just black text. Most versions are, according to AtariAge, common, with the blue label being slightly more scarce.


Imagic ran a contest called Defend Atlantis in 1982. The top four, highest-scoring players were to be flown to Bermuda for the Great Defend Atlantis Shoot-Off on 11/14/1982. The next 250 highest-scoring players would get snorkeling sets and the next 1,000 highest-scoring players would get a free T-shirt. At the contest, the top player would win $10,000 and the other three would win $1,000. Unfortunately, more than four people maxed out the score on Atlantis so Imagic created Atlantis II as a tie-breaker. Atlantis II was faster, harder and scored lower. Players that maxed out Atlantis were sent the game, snorkeling sets and the T-shirt. Those sent the game would have two days to play and then submit their highest score so Imagic could determine the Bermuda trip winners. Further information as to the top winner or whether or not the contest was completed is, as of 2012, unknown.

Colony 7

Atlantis was inspired by the arcade game Colony 7 which had no home versions at the time, so it was the closest you could get to the arcade.


When the city of Atlantis is destroyed, and the game is over, a blip can be seen leaving the ruined city. This blip is the Cosmic Ark, a spaceship carrying the survivors to other worlds...and this game's sequel.
