Your mission is defende New York city from meteor storm.
Use key 1 for left missile, key 0 for right missile and 2 for shield.
Beware, You can only fire one missile at a time and the shield does not always work.
For dramatic effect, If you can try it on real hardware on white/black tv, and turn
up the volume to feel the thrill of buildings that explode while you are powerless.
