This is where things get a little tricky. Not only are there the usual enemy sentries to deal with, you’ll also have to be careful of the gunship and watch out for the small bipedal tanks patrolling the base. Before you even enter the base, you should see a watchtower with a single guard up top. Interrogate him for the location of Huey Emmerich, and it’ll be marked on your map. Proceed to the base and scope out the area with your binoculars. I highly recommend using the Phantom Cigar to wait till nightfall before making your way into the base. Your chances of detection will be much lower and, trust me; you do not want to be caught by the bipedal tanks.
Enter the base from the left side of the compound. Continue to crawl on your belly and you should be safe from the two bipedal tanks standing guard on the road. Keep to the left for the path of least resistance until you eventually reach the large building with a vault roof – that’s where Huey is being held. However, the doors at the back of the building are all locked. You’ll have to enter through the door facing the east, with a guard standing right outside. Take him out with your tranquilizer gun and enter.
After a quick cutscene, you’ll have the option of either leaving the base with Huey on your back, or by taking the Walker Gear. I recommend using the Walker Gear simply because it’s much faster, and even if you get spotted by enemies, it won’t matter much once you reach the landing zone because you’ll have to face a much tougher foe.
