In this sector, you follow a NPC, the Rookie Alien Hunter. You follow him through a series of canyons loaded with groups of aliens. There are also several ambushes along the way. THE ROOKIE MUST STAY ALIVE UNTIL THE END! If the rookie dies, you must go back and get a new one, which is a major time waste because it basically means redoing the whole sector. Also, along the way through the canyons, there are several laser fences blocking the way. Do not run into these, as they will insta-kill you. When you come to these, stay behind the rookie and he will disable them. Once the rookie has disabled them, they are safe to pass through.
