In this sector, you clear the whole area of the bugs - just run through and kill em all to get maximum AXP. Ignore the ship and the unicorn in the center of the sector for now. Once the sector is cleared, everyone should gather under the ship. Only the mission holder should speak with the Unicorn Field Enginner, at which time 3 towers will spawn around the ship (Don't attack or heal these towers as the result is insta-death). **If these towers die then the generals wont come**. Waves of bugs will come in at staggered times from every direction, successfully kill them and keep the towers alive. After the waves, the generals come.
