Heavy Unit: Mega Drive Special (ヘビーユニット メガドライブスペシャル) is a Sega Mega Drive horizontal shoot-'em-up developed by Funari[1] and published by Toho.[1] An enhanced port of the titular 1988 Kaneko arcade game Heavy Unit, it was released exclusively in Japan in December 1990.[2]

Story

Humans have developed an artificial planet, "Le Tau," which is being attacked by aliens, and only the Heavy Unit transforming ship can stop them.

Gameplay

A and C shoot; rapidfire is an option. B drops a bomb, which you have an unlimited supply of but must collect as a powerup. Among the various powerups is one, labeled T, that transforms your ship into a mecha and back, which plays identically, except its bombs will home in on enemies. The ship has a spreadshot, while the mecha is power oriented.

There is a strange option called "control", it effects whether the ship/mecha has inertia or not ("organize" means inertia is activated).

The big head monster in stage 1 can be exploited for infinite score. This is exclusive to the Sega Mega Drive port, as the arcade version auto scrolls past the boss. The game lacks a score table

Versions

Heavy Unit: Mega Drive Special features the same amount of stages as its arcade counterpart but with partially modified enemies placements and behaviors. Stage 2 has now an underwater theme and an added raster scroll effect. Unlike the arcade release, the game also doesn't loop after finishing it.
