Gears of War 3 - Batten Down the Hatches

You get dropped right in the thick of the action. Fight through the locust here and watch out for the troika and boomer in the back left. There is a pillar between the tracks that has a switch on it. If you hit it, it will cause a couple of carts to start moving providing you cover here. Just past them is a large open area with the dock in the back. We have another troika and some more boomers but they are all the way in the back. There are some Theron guards with torque bows. They are your major concern. Work your way slowly up one of the sides and you should be all set. Go through the door.

Looks like that ship is in bad shape. Make your way through the area and into the next and you'll be ambushed. Watch out for the Guards above but don't worry about them too much, they seem to be pretty terrible shots. Of more import are the giant Serapedes. To kill these, you need to shoot the glowing tail end of it. It seems like it's lambent to some degree but it's also controlled by the locust? Anyway, try and clear these out. Be careful because they can deal a lot of damage very quickly if you're not paying attention. Once clear, before you exit, you'll see a blue shipping crate to your right (as you entered the area). You can go around behind this crate and right up against it is a collectable.

At the back right of this area is ammo and back left is the exit.
