SD the Great Battle is a shoot 'em up game with platforming elements at a top-down perspective. Players must shoot enemies while jumping over obstacles like pits. Three initial characters can be switched to during gameplay, Ultraman, Kamen Rider, and the RX-78-2 Gundam. Over the course of the game, three more characters will be available to be played as, Kamen Rider V3, Ultraman Taro, and the Knight Gundam. There are a total of seven levels to play through, and between them a cutscene will play, further advancing the story.
