Phozon

Phozon is an arcade game that was released by Namco in 1983 only in Japan. It is based on the science of Chemistry.

Introduction
In Phozon, the player must take control of the Chemic, a small black atom with red spikes which must adhere itself to passing Moleks in order to duplicate the pattern shown in the centre of the screen. The lone enemy in the game is the Atomic, a malevolent clump of balls which moves randomly around the screen and will kill the Chemic if it merely touches it. However, the Chemic can counter-attack by adhering itself to a Power Molek (these first appear in World 2) - but the Atomic has a nasty habit of splitting up and reforming to cover more ground, and even the Power Moleks are no match for the Atomic's deadly Alpha and Beta Rays which can destroy them (along with the regular Moleks) on contact.
