Astra Superstars is an airborne fighting game. The basic mechanics are similar to other 2D fighting games (including Sunsoft's own Galaxy Fight and Waku Waku 7), except all battles take place in the sky with the fighters floating in midair in a manner inspired by anime such as Dragon Ball Z. This allows more freedom of movement for the fighters, with the ability to "jump" both above or below each other. Unlike most fighting games, characters have normal moves and "super" moves that require building up a meter to use but no special moves. The goal of each round is to knock out the opponent, and each match is fought to the best of three rounds. Part of the health meter is green after taking damage, and this portion regenerates over time. Rounds are timed, and if time runs out, a judge determines the winner.

The English patch was released in late 2026.
