This is the last surviving alien installation that is defending the Interplanetary Gate.  With its destruction the Protectors will have a clear path to move on the Gate.
The enemy defenses are formidable and well-entrenched.  This is a solo-mission that depends on your speed and skill for success.
You will be inserted to the north of the compound, outside of the defensive perimeter.  This is an extermination mission - eliminate anything that moves.
