Encounter At L5

Beyond the orbit of the moon, a defenseless space colony is under heavy attack
from the ruthless Megalytes. You are their only hope. Armed with packets of
antimatter, you take control of an Antimatter Launcher. Suddenly the sky is
ablaze with Megalyte war ships. You must destroy them before their formidable
particle beams destroy you and the peace-loving colonists of L-5. It will
take every ounce of skill and cunning at your disposal to blast the evil ones
out of orbit.
