"THE BATTLE BEGINS! Wave after wave of mindless metal machines march toward you. Summon the full power of the Mega Buster and melt them down to size. Pick up energy pellets and weapon capsules to keep up your strength. Keep a eye on your energy meter in the top left corner of the screen. Because once your energy is gone, so is your life! Run, jump and climb through the mazes of twisted corridors to the lair of the robot master. Once you arrive, it's going to be a cybernetic slugfest and only one of you will survive. Keep on pounding the robot master with your weapons until his energy is depleted. Once he's been deactivated, grab his weapon and add it to your arsenal. Now you're ready to take on another of Dr. Cossack's crazy creations."
