Gears of War/Act Four: The Long Road Home

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.
