Head through the dark tunnel and pull on the lever at the end to open the door. Hold LT after Ishi foolishly shoots the glowing sack. After Ishi and Trishka calm down, pull on the lever and head up the stairs.
Log into the Dropkit and continue up the next set of stairs. When Trishka gives you the order, shoot the spore (the glowing sack in the middle of the room), then sit back and watch the Skulls kill each other.
After Ishi opens the gate for you, head up the steps and what the----!!! Hold LT when prompted to. After Ishi gets swallowed by that huge Maneater, wait for Ishi to send you a signal. Then follow Trishka.
Head through the huge columns and down the steps. Kill all attacking Skulls as you head down the steps and make sure to use the surrounding spores to your advantage.
After you get down the last row of steps, use the Dropkit to the right and head down path. Use your leash and kill the Maneater to the left. Then kill all of the enemies in the center quad area, but beware of the Maneaters around the perimeter.
After you make the left and are looking down the path with the two red spherical balls, pull out your sniper and shoot the Skulls off in the distance. Use those spheres to your advantage.
Once the area is cleared, head up the steps and through the cacti-filled path. Kill hte Maneater to the right of the Dropkit, then use it if you need to. As soon as you hear the helicopter, take cover behind one of the pillars.
After it flies over to the next area, follow Trishka over there. Kill the Creeps on the floor and the Maneaters will actually take care of the copter. One of the boss Skulls will show up on the steps----use annihilator blasts on his back to defeat him.
