Act 3: Belly of the Beast - 3. You Must be this Tall to Die

There will be two guys to the right as you start, no big deal. Get ready for a couple of Dark Wretches to attack from above; just use blindfire or whatever you wish, reload often. The big room has two Drones, but ignore them. The next tunnel has a lone Drone on the left side so take him out. Then be ready for two Wretches down the way. There's a Boomer in the last area, but you can ignore him too. That's it.

*I hear you can take the other path, but it probably doesn't matter.

Grab the ammo and continue onwards. The next room has a brief encounter with a Wretch; I got him once and then he was on the other side, so go figure. Push the button and kill the unsuspecting Wretches up ahead. Then wait around for two more to drop down where they were. Grab the ammo on the side and go on. When you are passing the tunnel you will have one sneak up on you from behind, and another is waiting to up ahead; kill him if you can.

When you approach the end of the platform you will need to wait for a Boomer to jump on, then you need to run back and take cover. The other two have a Boomer as well, so just be quick and hope they can help you out. Jump on and enter the mines.
