Combatrobo Zakato is a Korean-made sci-fi side-scrolling shooter in which the player controls a giant mecha sent into a hostile area in deep space to fight mechanized aliens. Though the mecha can move freely in eight directions, the game doesn't play exactly like a scrolling shoot-em-up, because the screen scrolls horizontally or vertically only if the player character moves in the correspondent direction. The player can choose various weapons and limited ammunition types for each mission, however, all weapons can only shoot forward. The player can turn the mecha around by pressing a separate button. Stages usually end with boss battles.
