Act 3: Belly of the Beast - 4. Caves of Darkness

Follow the path and take the right path at the fork to reach a Frag and COG # 22.

Go back to the fork and take the tiny path to some ammo. Come back and take the final path and fight a couple of Wretches(more ammo in a crevice to the left). Continue on and when you see the open area under a structure be ready for two waves of three Dark Wretches. Keep going and slip away.

Grab the ammo in the blood and go forward. Get in cover and take out the one guy up the steps to the right. Then take care of the two waves of Drones. Ammo in the room up the steps (cheap scare) and COG #23 below the steps.

Onwards you will run into a sniper on a ledge, quickly shoot the thin stone pillar to bring some rocks down - cool huh. Go on and handle the many Dark Wretches after those rocks blow away.

After the numerous slabs, take out the three petty creatures that show up. Move up until the Boomer shows up across the way, take out the couple of Dark Wretches, and then whip out the Longshot to blow the big guy's head off (I sure hope you still have the Longshot). Go onward, grab some ammo, and then fall.

Get ready for some intense action as you are swarmed by Dark Wretches. Again, shoot from hip, move around, and dive away. Grab the ammo when all is over and continue (the last beast will be kill to open the path).

Choose the right path, and when you pass the two rocks you will be rushed by Wretches and a Drone. Melee or fall back to kill the Drone, then handle the rest and try to help out Dom on the other side. Move up and wait for another rush; do much of the same. There will be one last rush, but this time by two Wretches and two Grenadiers; get to cover.

Go down the little slope and grab the ammo and Frags. In the narrow path you need to take out the three Wretches on the ceiling ASAP. Then take care of the six or so Drones down the way. May lob a few Frags to hasten the fight's end.

In the open there is some ammo and COG #24 to the right. Go on to the boss.
