The Sega Zaxxon arcade game is a unique isometric 3D
shoot-em-up arcade game that was released as both a standing
cabinet and cocktail table in 1982.
This article looks at the marketing
brochure and a few videos on how the game actually plays.
This arcade game was ported to the whole range of 8-bit
microcomputers at that time.
At the time of its release, Zaxxon was unique as it was the
first game to employ axonometric projection, which lent its
name to the game (AXXON from AXONometric projection).
Wikipedia claims that Zaxxon was the first arcade game to be advertised on television.
We can't verify this claim, but you can watch a Zaxxon advertisement for yourself.
This particular version looks more like an industry marketing campaign than
a consumer orientated advert.
