Move through this building until you come to a lobby of some kind. Watch the man from above come into the room. He'll be dead. You should probably take his weapon if you can. There's a window here that you need to shoot at to exit the room. It will be marked for you. Leave the building and you'll be outside.
After you watch the chopper come in and you decide to go down and save Gould, go right and use the lines to rappel down to the lower level. You'll have to make your way through some seriously graffitied alleys. You'll eventually come out to a highway that looks a lot more like a parking lot. Drop down into it and take cover. If you look forward, you should see some enemies near a burning APC and a man standing on a broken bridge to the right.
Prepare to take them down, starting with the man already on the APC. There's a case of sticky grenades on your side of the orange jeep. Using these might thin the enemy quite a bit and there's enough enemies that you might be able to pick up three of them for an achievement. Once the enemy on the APC is down, it's more important to watch the bridge for enemies before the enemies on the ground. Keep that clear and move forward when you can. Remember that you just picked up a pretty good Marksman Rifle.
Slowly move up to the APC and you'll find enemies coming in from the distance. They'll be dropping in over the walls in the distance. From the APC, try to clear as much as you can leading up to the orange shipping crate on the left side. Take cover behind it and slide far to the left. When you reach the highest point, you can look over it and see the turret. He will pay no attention to you so just take him out. You should also be able to kill a few other enemies in the area before you need to head down to see.
Move down the shipping crate and go around the corner. Clear any remaining enemies and get over to the bus ahead. Go around the front of the bus and move up using the crates on the right side. Don't go past these crates because there are more enemies way ahead. When you clear out the area directly ahead of you, you'll be safe. At that point, move up and make sure you check for ammo before continuing on. Before you enter the alleys, check to the right of the alley should be a checkpoint with a dead soldier. Just to the right of the dead soldier should be a stop sign and there is a piece of intel on the stop sign. You'll have to go through some more alleys until you come out to a large plaza.
The plaza will start burning and you need to avoid walking on the burning people. As you walk across to the other side, three enemies will appear. Two of them will be regular enemies but a heavy enemy will appear too. You can just keep shooting him or use grenades. Usually two grenades will work. If you are going to shoot him, go for the head to conserve bullets. It's possible to destroy his mask and get under it but it will still take a lot of ammo.
*Achievement: Recon
Kill him and move ahead. Before entering the next building and getting out of the smoke, you should see a piece of intel just to the left of the door. You'll come to another of those choices. You can choose whichever you like. If you let Lugo save Gould, you will have to retread the same space but you will have to fight though. There shouldn't be too many enemies. If you don't, you'll sneak through and just do as Adams instructs you to do. The former option will get you the
