The player must help ALF (a.k.a. Gordon Shumway) as he tries to rebuild his spaceship and go to Mars to visit his friends Rhonda and Skip. The player travels through ALF's neighborhood, the ocean, and even to the moon collecting and buying parts for his spaceship. Along the way the Alien Task Force will try and apprehend ALF and if they do so the game is over. Similarly, ALF will be instantly defeated by any enemy he touches, so the player must be careful to avoid everything.
