Gameplay
The player's ship had two forms: a space-ship and a giant robot. Players started controlling the Heavy Unit in its space-ship form as default. As they progressed, they could change the ship into its robot form, thus changing its firing mode and mobility. A checkpoint was active however and the Heavy Unit only had one hit.
Power ups are dropped by a specific enemy ship which appears in fixed points during the levels. Every level of the game contains a mid-boss and a final boss.
Story
Set in 2013, humankind's first artificial star and planet, "Le Tau", is under attack from genetically modified alien monsters. The player must navigate a "Heavy Unit", a heavily armed, transforming mecha, in order to defeat the onslaught and protect the human colony.
Reception
In Japan, Game Machine listed Heavy Unit on their January 1, 1989 issue as being the fifth most-successful table arcade unit of the month.
