Galactic Warriors

The game is controlled with an 8-way joystick and three buttons: the attack button, the guard button, and the weapon selection button. There are six stages, each with different themes and environmental effects based on gravity. Some other features introduced in Galactic Warriors that were used in later fighting games include block damage, air-blocking, the ability to shoot/throw projectiles, the ability to execute multiple attacks while airborne, a modern health bar (as opposed to a health meter with notches like in Capcom's Mega Man series that made their debut two years later), the ability to switch between armed and unarmed and attacks of varying levels of strength.

Another feature introduced at the time allows the player to choose one of three Mechas, each with their own movesets: Samson, a medium-sized robot equipped with a sword; Gaea, a female-presenting robot armed with breast projectiles; and Poseidon, a robust robot with an extendable limb. When one is selected, the player must use it to destroy other robots in each planet. Other than the playable characters, there are several non-playable characters and bosses with original designs and unique movesets. In the final battle, the player will face the same character he or she chose. After defeating the final opponent, the game goes back to the beginning and the player's chosen character and the opponents will have an extra weapon.
