Zaxxon

Zaxxon is a 1981 scrolling shooter developed and published by Sega as an arcade video game. It was developed with assistance from Ikegami Tsushinki, the same team who had programmed Nintendo's Donkey Kong the same year. The player pilots a ship through two heavily defended space fortresses, and the outer space areas between them, to confront the Zaxxon robot at the end of the second fortress. Zaxxon was one of the first games to employ axonometric projection, which lent its name to the game. The type of axonometric projection is isometric projection: this effect simulates three dimensions from a third-person viewpoint.
