Campus Grinder
You and the squad are on the hunt for Marcus's Father's House. Your King Raven copter gets shot down in the middle of the city.
Secure the Courtyard
You must clear out the the Locust in the courtyard here. The first wave is comprised of Drones, Grenadiers and Locust Sniper. Once you clear the first wave, from the south (if building entrance is north), some more Drones along with a pair of Theron Guards come out of the buildings.
If you thought that was a tough onslaught, two Boomers decide to drop in on the party. One from the East and one from the North East. I decided to surprise the one at the East with some grenades at his feet, but he didn't like me much for that. Stay in cover and take them out safely. Instead I found it safe inside the building.
Once you are clear, collect ammo from around the level. There should be almost ammo and every weapon so far available to you on the ground somewhere.
Secure the Contemporary Combat Center
Take the Streets (Right)
Take the Building Path (Left)
In this path you travel through the buildings along the street, backing up the rest of the squad below on the streets.
Once upstairs, you'll come across a Theron Guard, after the guard is defeated check out on the squad below. A few rooms later, a Seeder emerges outside on the streets. Once you take care of the immediate threat of a Drone, a pair of Wretches and an occasional Nemacyst, use the Hammer of Dawn found in the room here to take the Seeder out.
Once the Seeder retreats back into its hole, look for another Emergence Hole to open in the middle of the courtyard. Have the Hammer of Dawn ready to close it right up before too many enemies get out. The hole will contain at least two Theron Guards and a few Drones so the sooner you close it the less will escape.
Your squad mates are now stuck and require you to open a doorway so they can continue. Work through the building until you find a wheel on the wall. Open it up to let the rest of your squad through.
Continue through another burned up building and take part in a fire fight on the street with the Locust who are on the other side fighting the rest of the squad. There is one Locust Sniper with some Drones here flanked by a few Wretches. Clear them out and continue into the building ahead of you and back out to the street. You are now reunited with the rest of the squad.
