Phozon

Phozon (フォゾン, Fozon) is an arcade game that was released by Namco in 1983 only in Japan. It is based on the science of Chemistry, and was the first of only two games from the company to run on three Motorola M6809 microprocessors instead of just two. It was also the first game from the company that had been confined to Japan since Kaitei Takara Sagashi in 1980.
