Zaxxon is a 1982 isometric shooter arcade game developed and released by Sega. Some sources claim that Japanese electronics company Ikegami Tsushinki also worked on the development of Zaxxon. The game gives the player the experience of flying a fighter craft through a fortress while shooting at enemy entities (missiles, enemy gunfire, etc.) The object of the game is to hit as many targets as possible without being shot down or running out of fuel—which can be replenished, paradoxically, by blowing up fuel drums.
