Controls

 * Joystick: Use the 8-way joystick to direct your ship (yellow for 1P, purple for 2P) around each planet; they will not be killed if they touch the ground.
 * Firing Button: Use this button to make your ship fire shots at the enemies; if you have autocannon laser rounds, hold it down to make it fire rapidly.
 * Select and Fire Special Weapon Buttons: Use these buttons to cycle through, and fire, each kind of special weapon you have got in your arsenal.
 * Start/Transform Buttons: Push these buttons to begin the game as player 1 or player 2 or transform your ship into its turret form (and back again).

Ships
The protagonists of the game; Player 1 controls the yellow ship, while Player 2 controls the purple one. The gameplay's somewhat similar to Sega's Fantasy Zone (which was released five years earlier and also used a Yamaha YM-2151 FM sound chip), in that the ships are not always moving forward, can fly in either direction and will not be killed if they touch the ground) - however, when all the enemies on a planet have been killed, there will not be a boss battle (the closest this game has to boss battles is when a Saurian dreadnought retakes a previously-secured planet on the map, causing it to start flashing, and automatically forcing the players to return there and destroy it if they are close enough to it). Although the game always starts on the planet of Phobos (which is named after the first moon of Mars) you will have between 10 and 30 seconds to direct the shuttle (which beams the two ships down at the start of their visit to each planet) to any of the twenty-one remaining planets upon the map after clearing it; however, if the Federation Supply ship is passing by, you can direct it towards that instead. Both players will then have fifteen seconds to select one of the eleven types of special weapon and press the Start Button to buy it for a Trilithium Crystal (if they do not have any Trilithium Crystals they shall have to insert another coin and use its credit instead) - and they shall also receive an extra life with every purchase, which can be very useful, because it only takes one hit to kill them. Both players will also receive extra lives at every 50,000 points by default; once all twenty-two planets have been secured, the shuttle will automatically fly towards the Saurian Mega-Star "Apocalypse". If you are lucky enough to reach its core and destroy it, the game will end - and award one free credit.
