Battle your way through a mad onslaught of crazed machinery. The Robot Masters pour on more insane weapons than you can believe! They clank, buzz, crawl, shoot, and blast from every direction. Explore every room and corridor. Climb every ladder. Dodge, slide, leap, and fire to blast your attackers or at least get away!

You start the round with 3 chances to make it through. Watch your Energy Meter at the top left corner of the screen. Your energy drains away as you take the crushing blows your foes dish out. Good thing you've got a steel noggin!

Pickup Energy Tanks, Energy Pellets, and Surprise Boxes to gain back energy and chances. When your energy runs out, you lost one chance and the round ends. If you have chances left, you'll start again.

Keep going! Destroy all the robot fiends in this level, and you'll face the diabolical Robot Master. His Energy Meter appears to the right of yours, so you can keep an eye on who's winning!

If you lose all your chances, the game ends. But if you demolish the Robot Master, you gain his weapons and capture the energy crystals from his world. Then you can take on the next maniac!
