Play Wakusei Aton Gaiden (Japan edition · Japanese) Online

Select "Play Alone" or "Play Together" on the title screen. Use the cross button to move your spaceship, and hold A to fire continuously to defeat enemies. If you get hit by a bullet, you will lose 100 points and it will become a single bullet and move slower, so it is important to use repair items to return it to its initial state. Shields block enemy bullets for a certain period of time, and bombs wipe out enemies on the screen. When you defeat the quizzer bouncing at the top of the screen, a three-choice quiz will begin, so move to the missile numbered 1-3 that corresponds to your answer and shoot it with A. After about 8 minutes, defeat the next quizzer and proceed to tally your score.

Cross button: Move the spaceship up/down/left/right. A: Fires bullets (hold down to fire continuously). On the quiz screen, answer by shooting the missile with the number you think is correct. B/START/SELECT: No function during play. There is also no pause function. In two-player play, each player uses a corresponding controller.
