Released in January 1986.

The actual licensing of the game went from Taito to Tecmo who further licensed the title to Romstar. This was a common distribution technique for games which were perceived as being 'second tier' or less when compared to 'hit' games. The game is still great fun and is, unfortunately, underappreciated.

While popular history seems to think that Data East designed the game (because the pinout matches Data East pinouts) the internals of the two 6809 processors appear to be a little more complicated than that. The design internally is rather Machivellian. It seems almost like it was created by a hardware designer who did not like software programmers!

Elout de Kok of the Netherlands holds the official record for this game with 1,343,700 points on May 2, 1986.
