For action fast and furious, take command of a rocket-powered fighter-interceptor flying a few hundred feet off the deck. Your mission: attack and destroy alien silos defended by several squadrons of alien rocket-craft. You must react instantaneously. You are a few hundred feet above the terrain in a narrow canyon. That's where the aliens have dug in. Maneuvering room is severely limited. Meanwhile, earth is slowly coming into target position for the silos. Remember, you alone can save earth. Don't miss.
