The AA has finally tracked Grull to his homeplanet: Earth. Your mission is to find your way out of your underground prison, and lock Grull in the cage inside the cave of death. He has killed General Baxter (play "Baxter Blaster" by gabesworld), and is trying to murder all the other agents. Lock him up, and let us hope that nobody shall ever awake Grull again, for if they do, the universe will be in mortal danger once again.
