Shoot down all opposition in this first walkway - also remember to look across the opening. Drop down into the open and head to your left. There is a small, gray area that resembles a door. Once approached, it will open to a secret area with Combat Armor. Return back out and step on the platform to elevate you to the surface. When you enter this door, hit the green button right away to drop a crate on a BeserkerΓÇÖs head! Then jump down and kill whoever is left - most enemies will charge you from underneath where you were standing so watch out.
