When you start, get Fenix to jump on the turret. Kill as many locust as you can as they stream out of the hole in the ground. Shoot the brumak too if you like. As you are leaving the rocky area, you will be attacked by another rig that has been hi-jacked. Use the turret to kill the locust as they appear on the deck. Try and keep them off of the rigs turret as best you can.
After some time, the other rig will drift away from you, making it a little harder to hit those on board. However, you will pass by a small raised area from which a few grubs will jump on board, kill them as fast as you can and when the rigs come back together again, you will now also have the threat of grappling locust. Listen out for a distinct clanking sound, to signify a hook has landed on the rig. Find and shoot the hook or a locust will climb up it onto the deck. When the other rig ventures away, jump off the turret and deal with hooks or locust on board Betty and when it is close use the turret to kill those on the other rig.
After a lengthy battle with the scurvy crew of rig G53, Dizzy will spot a bridge up ahead. But its too small for two rigs to cross. Now is the fun part. Get back onto the turret if you are not already there and shoot those on the deck. The rigs should come together pretty hard three times, each time; the window at the very front of the other rig will become more damaged. After the third, you will be able to shoot through the window and kill the grub piloting the rig to send him and his crew plummeting to their doom.
Following the bridge, you will regroup with several other rigs and some helicopters. Man the turret and listen out for the stomping coming from your left. It’s a brumak! Shoot it until it is hit by an explosion and then turn the turret forward, shoot at another brumak just further up the road on the left. After you kill it, you should see a large group of locust running in front of the rig. Shoot as many of these as you can. If you don’t shoot them all, they will be using the hooks to climb up onto the deck. Kill off the immediate threat and ignore the brumak, it will take out its anger on another rig anyway.
Next up, a corpser will emerge from the ground in front of you, lay into its face with the turret when it rears back and it should retreat back down the hole from whence it came. A shot ways down the path another brumak will approach the rig from the front shoot its face and guns with the turret to take it down and continue on to the next mission.
