Drones carry you and Gideon (both wearing AST suits) along the New Baghdad canal. As enemy boats, vehicles, and soldiers show up, light them up with your AST weapons, controlled just as they were at the end of the previous mission.
When prompted, detach from the drone to be dropped into the water. Walk along the bottom of the canal, and enter through a hole in the wall. Follow Gideon up a staircase to reach the command center.
Just inside, enemy forces start attacking. Mow them down with your guided missiles and Gatling gun.
Follow Gideon into the silo as hostiles attempt to keep you out. As long as you don’t let yourself get surrounded, you can dispatch these foes easily with your powerful weapons.
Continue behind your teammate as he descends down a level.
Try to clear out each area before moving on. Occasionally, though, an enemy gets behind your location. Pay attention to the blood smears that show the direction from which you’re being attacked, and quickly eliminate hostiles who confront you from behind.
Clear out the attacking hostiles as you take another staircase down, followed by a ramp. Watch out for rocket launchers and incoming grenades, as these can cause some serious damage if they hit their target.
When it appears that you have reached a dead end, the wall lowers as four ASTs join the fight on the other side. Use your rockets on them whenever available, and take them out before targeting the rest.
With the hostiles taken care of, follow Gideon through the door and into the vehicle access area.
Follow the path to the end, and locate a hatch in the floor to the left. Approach the nearest piston, and once Gideon is in position, grab it. Rapidly tap the Use button to pull it off and hop down the shaft.
Holding the Aim button sticks out your left leg to slow your descent, while the Fire button does the same with your right leg. If you do not slow down enough, you will die at the bottom. Hold both buttons the entire time until you safely reach the exhaust vent.
Walk behind your partner until you reach the rocket. Fire all of your weapons at its thrusters until you destroy it.
When you gain control of your handgun, fire at the guards at the end of the hall. Six enemies total enter the area.
When prompted to do so, rapidly tap the Use button until you are released from your Exo. Sprint up the steps, and run after your target. Keep the Left Stick pressed in the entire time, and make sure you react to each obstacle quickly. Otherwise, you will lose the objective.
Slide under the closing gate, and immediately melee the guard as he drops in front of you. From there, follow the onscreen prompts as soon as they appear to complete the campaign.
