Terminal Terror

Your mission is to eliminate any perimeter forces and move into the hangar and dispose of any resistance. Once in control of the hangar, you must slowly move through the airport and neutralize Riggs' henchmen. Keep in mind that there are many innocent civilians depending on you to keep them out of the line of fire. You must also gain access to the main power line and help restore power to the control tower. Flights are still operating and this potentially lethal situation must be averted.
It is also rumored that Bruno Riggs'men have discovered the entrance to the sewer tunnels running between the closed SAC hangar and the converted airport terminal. There is high probability that if they found the sewer system, weapons stored in secret SAC tunnels could now be in their hands. They must be stopped.
The sewer tunnels also contain another danger, alligators. As if a bunch of wild men running around with guns weren't bad enough, now you have to contend with possibility of stepping on something with very sharp teeth. And just to add one further element of terror, reports say that Riggs has discovered two CIA undercover agents working in his midst. One of the agents is Susan Riker. She is reportedly chained to a jet fuel storage tank that might be wired with a time bomb. You don't like this information one bit. Especially since Susan Riker happens to be your fiancee. But your most important assignment tonight is to recapture Bruno Riggs.
He must not escape. He must be brought in alive to stand trial for his crimes against humanity. No more innocent lives can be lost.
