Can you save the galaxy by blowing up the alien-inhabited planet... and get off the planet before you explode? You must burrow deep inside, finding your way through the underground maze while battling the Planet Protectors. If you can get to the center, plant your one bomb and try to find your way out. It's only a matter of seconds before the planet goes BOOM!
