You take part of the one remaining pilot in the Federal force under 
attack in the city of Xenon. The alien invaders have swept away the 
defenses and all the population has been evacuated. Well, nearly all of 
it. There are still people in the city who must be brought out to the 
spaceport and safety. So all you have to do is fly through the city and 
pick them up, avoiding the emery who have reached the city suburbs.

     Those left behind are hiding in bunkers either in the city or 
surrounding areas. The spaceport is on the other side of the city from 
where you are, so in order to rescue the refugees you must land close to 
the bunkers as they appear in the screen, stay around until all the 
refugees have made it into your ship - whatever the aliens are doing to 
stop you - then move on as quickly as possible. As the one and only poor 
sucker who can fly a Panther ground attack craft - you're hero for 
today.
