Heavy Unit (Japan, older) — About this game
Heavy Unit (Japan, older) changes both its weapon coverage and its physical size through transformation. The default spacecraft’s forward gun and dropping auxiliary missiles give way to the robot’s laser and homing support after collecting a T item. Becoming larger also creates more exposure to enemies and the terrain. A lost life removes collected upgrades and returns the craft to a checkpoint, making recovery part of the next approach.
