At the beginning of the activity, CJ and Edison board the rocket ship. First, the player must inspect the planet map on the wall, which shows all the planets in the solar system. A clue will be read aloud, and the player must figure out which planet the clue refers to in order to find out which planet is under attack.
After the player has selected the correct planet, CJ and Edison will fly there. CJ reads the sign that says "Welcome to Mercury/Venus/Mars/Jupiter/Saturn/Uranus/Neptune/Pluto." After landing on the planet, the player must control a land cruiser using the arrow keys to move and the space bar to shoot. The player must shoot all of the robotic aliens without letting the cruiser take too much damage. The robotic aliens never invade Earth.
Difficulty level differences
- Level one (Scout): Clues to identify the planet under attack feature solar distances.
- Level two (Explorer): Clues to identify the planet under attack feature physical properties of the planet.
- Level three (Trailblazer): Clues to identify the planet require interpretive logic based on the clues in the first two levels.
- Level one (Scout): 20 aliens attack, but do not fire any shots.
- Level two (Explorer): 25 aliens attack who randomly fire shots at the land cruiser. Asteroids also target the land cruiser.
- Level three (Trailblazer): 30 aliens attack who fire direct shots. Asteroids also target the land cruiser.
