Imagic's Atlantis turns the fixed shooter inside out: you do not move at all. Designed by Dennis Koble and released in 1982, it has you defend the sunken city from waves of Gorgon ships using three stationary gun posts, one in the center and one at each end of the city. The ships sweep across the sky in rows, dropping lower each pass, and the lowest ones fire death rays that wipe out the city's installations one by one.
What makes it work on the Atari 2600 is the choice of which gun to use. The center post fires straight up, while the side posts shoot diagonally across the screen, so targeting becomes a matter of timing and angles. When the last building falls the game ends, setting up Imagic's sequel Cosmic Ark. A tougher contest edition, Atlantis II, was released for a high-score competition.
Tips for Atlantis
Prioritize ships on the lowest flight path; they are the ones that fire on the city.
The side guns cross the screen at an angle, so fire early and let the ship fly into the shot.
