Galaxian

Galaxian is a shooter arcade game developed by Namco in 1979. It was released by Namco in Japan and a few months later by Midway Games in North America. The game was developed to compete with Taito Corporation's Space Invaders, released a year earlier, and featured a similar space theme. The player controls a space ship in the bottom part of the screen and shoots at enemies descending from the top of the screen.
