Start off by walking forward around the pillar and into the room behind the pillar, were Stone will debrief you on what your next assignment is. When you have your orders turn around and head back into the hallway, move forward and look left for a stair case to go up.

Once you are up the staircase proceed to your way point. Once you have met up with Graves, go to your next objective. Proceed up the staircase and purchase a sentry tower. When the sentry is placed make your way to your next checkpoint to encrypt the transmission.  When you get to the console hold down the activate button to encrypt the transmission. After you finish encrypting the base will get attacked!

You are too hold your position an defend the tower. It is recommend that you use medium range weapons (if you don’t have any use the supply depot that is on the upper level) and stay on the upper level. Try to not let the enemy get underneath the upper level. Once you have killed all hostiles you will be ordered to place mini-gun turrets around the tower. Plant one turret in-front of the tower (near supply depot), and another behind the tower. Tangos will soon drop in so plant the turrets fast. Two waves of tangos will drop in on the right side of the tower (if facing the supply depot).  After the two right waves, there will be one wave of hostiles coming in from the south of the tower. When you have killed enough of the south wave, Stone will contact you saying one of their ships are down, and he wants you to investigate it there will be about 1 or 2 hostiles running to the crash site as well to destroy the ship so run fast.

Kill the 1 or 2 enemies running toward the ship, but be careful when approaching the ship there will be about 2 more guys that will come out and start shooting when you get close enough. When at the ship walk around the left side of it and under the wing will be the intel you were sent to get. After you acquired the intel stay put and wait for your  mech delivery. Once a mech has dropped get in it, and start heading to your next checkpoint, you will have numerous encounters with hostiles, so be prepared (make sure you know how to work it). From were you get your mech walk a little bit forward to a generator compound and clear it out, including the ones that drop in, when they are dealt with leave the mech and reactivate the generators.

When the generators are back up and running get back into your mech and start moving toward your next objective. At your next objective clear out all the hostiles and be ready to defend the two satellite dishes. When defending be cautious because most of the troops that drop in have missile launchers.  When you have successfully protected the satellite dishes the Mission is complete!
