The fourth level is where the beat 'em up game turns into a shooter, and the Dark Queen throws asteroids, mines, and UFOs at the spacecraft controlled by the player. The first level of the seven-level game takes place on the tail of Colossus, the second on the interior corridors of the ship in level two, the third in the ship's base, and the fourth where the player attempts to destroy the ship from the outside while on a small space craft. The brothers agree, and all five immediately take off for the Colossus in a mission to stop this two-pronged threat.

Deciding to even the odds, the Battletoads contact Billy and Jimmy Lee for help. Apparently, the Dark Queen is back with another plan to dominate the galaxy, and she has allied herself with the Shadow Warriors (from the Double Dragon series) to supplement her forces. However, one day the Earth's military is neutralized and the giant spaceship Colossus emerges from the moon.

After she was defeated by the Battletoads, the evil Dark Queen flees to the outer reaches of the universe and the 'Toads and their mentor get on with their lives.
