You can't hide from them forever so pick your moment and shoot the enemies here. There will be four of them to start with. After you kill the men in the lower area, be sure to watch the bus to the left as it's a popular flanking position. When the two snipers appear, run into the open and hit Bullet Time to try and take them out since they have a large positional advantage. Once you are safe, look for a broken bus with a missing top. Inside, you'll find part of the Golden FN FAL. Looking at the snipers' building, there's a large blue bus to your left. Go around it to get to the gate to the next area.
In the fuel depot, watch out for the sniper above the spot where the previous two were. Make your way forward along the left side to the barriers for cover. You can try and shoot your way out through the dozen or so scattered enemies or you can simply shoot the fuel tanks to kill almost all if not every enemy in the area. Once they are gone, more enemies will appear. Use Bullet Time to try and take them out as they appear and watch out for flying grenades. There will be an office by the front gate and if you check inside, you'll find the Office Newspaper inside. As soon as the coast is clear, head back to where Giovanna was to get to the next area.
You'll enter a bus depot and a few enemies will move into the lower area. Max will grab onto a chain and ride it down to the lower level. If you manage to kill all the enemies before you hit the ground (in Free Aim), you'll get an achievement. Just work your way from right to left on the first group of three and as this is happening, you'll get two more enemies that will come in from the right side of the large door. Kill them quickly and then start picking off the last few enemies from the left as they come in. The goal is to kill all the other groups so you can hit the last group when they bunch up as they are coming in. You should have an automatic for this so aim for the chest and shoot. If the gun doesn't kick up to hit their head, a few rounds to the chest will kill them anyway.
*Achievement: The Only Choice Given
Once you've landed and the enemies are dead, check the paint storage room to find part of the Golden M4 Super 90. Hit the large button directly in front of you and then explore the area. Going through the large door that opens will bring you to a maintenance area with quite a few enemies. Pop out of cover and activate Bullet Time (if you have it). Hit one of the glowing control buttons on either side of the lifted bus to drop it down on enemies, then work on the enemies that are likely working up your flank on the left.
If it seems safe to do so try and make your way over to the rack of tires. It will provide good cover but give you a better vantage. From here, check for an enemy around the corner to the left of the bus and a couple more coming in through a door on the right.
A couple of guys will appear on a catwalk above. Shoot them off and then more enemies will appear on the lower level. Hit Bullet Time if you have it and try and find a good direction to Shoot Dodge. Kill any enemies that you can in Shoot Dodge and take cover. There should only be about four enemies total. Once you've killed them, Giovanna will lower the stairs and you can get up to her. Before you go up, check the small office under the stairs to find another part of the Golden M4 Super 90.
The next room seems to be a painting area. You'll be on a raised catwalk with a bunch of enemies below. Make your way down the stairs and kill the lone enemy at the back of the bus. At the bottom of the stairs, immediately turn left to find two more enemies entering this around by the front of the bus. Kill the two of them and go around the front of the bus. Shoot into the bus because there will be an enemy in there. There will be one enemy just to the left of the bus. There will be one last enemy by the back left of the bus. Make sure you go into the bus and check the back before killing the last enemy to find part of the Golden FN FAL. Take him out and you'll make your way and enter into an office building.
There's a big shoot out at the top of the stairs. Make a Shoot Dodge over the desk directly in front of you. Kill the two enemies in front and slightly left by the windows. If you kill them quickly, try and take out the enemy to your left before you land. Take cover behind this desk and watch for two more enemies who will rush around the corner and head for the desks to your left. They will make for easy targets. There will be a couple more enemies in the back corner office and by the large window near it. Make your way towards those offices and kill any stragglers coming up the stairs to the left. When you are clear, check the office on the far side from the stairs for the last part of the Golden M4 Super 90. Whatever you do, don't go through the giant window, make sure you go down the stairs.
At the bottom of the stairs will be two enemies, one of which will be in the nearby office. In the hallway, check for a Campaign Poster. Go into the office and around the desk. At the floor by the chair will be the last part of the Golden FAL. In this room will be a button by a window that will open the double doors. A man will appear and you'll come running around the corner to kill him.
You'll end up outside and hop on a bus. There is an achievement for killing every enemy on this trip which is not an easy task but it doesn't require Free Aim so change that if you think it'll make it easier. Enemy 1 will pop out from behind two blue vending machines. Kill him for some Bullet Time. Enemies 2-4 will be at the end of this platform. Use Bullet Time and be fast here because the first one can slip by quickly while the second one can be obscured by some pay phones.
When you come around the corner, you'll see a bunch of enemies, roughly enemies 5-14. Immediately blow up the gas tanks and then turn right to shoot a couple of survivors by the stationary bus. Once they are dead, turn left of the gas tanks and you'll likely see a couple of survivors here too. This section shouldn't really cost you any Bullet Time so save it.
You'll come around another corner with enemies 15-18 next to a red bus. These can also be taken out without Bullet Time if you're accurate. If you need to use some, that's ok. You'll enter a tunnel at this time.
When you regain control in the tunnel, you'll see enemies 19-21 coming down some stairs on the right side. Use Bullet Time to kill them and then when you turn the left corner, you'll automatically enter Bullet Time again. There will be enemies 22-24 here and one of them has a rocket launcher. Do NOT shoot him yet. Make sure you shoot the enemies on either side of him first because once you kill him, you likely won't have time to kill the others. If you kill those two first, you'll stay in Bullet Time while you kill all three of them.
You'll come to another bus platform. On the left side of the road will be enemy 25 so make sure you get him. Kill enemy 26 right at the start of the platform and then 27-29 will be just ahead on some stairs. Try to take out the lead guy quickly and then enter Bullet Time to get the next two. Enemies 30-32 will be under the stairs a little spread out. A little past them will be enemies 33-35. Killing them should trigger the achievement. Note that since there are over 30 enemies on this course, it is possible to get the Colder Than the Devil's Heart achievement as well though I believe it requires you to shoot every enemy by the fuel tank and use the Bullet Time sparingly to do so.
*Achievement: Trouble Had Come to Me
This last part is actually pretty simple and a good opportunity for a couple of achievements. You'll be in the bus and unable to move. There will be lots of people shooting at you and a you'll have a decent amount of Pain Killes. The first achievement is simply shooting 10 grenades and since this checkpoint starts with Bullet Time and a grenade throw, you can just reload it until you get it (though it's really not necessary to grind this). The second achievement is for getting 10 kills in a single Bullet Time.
To do this, shoot the first grenade and just sit behind cover letting your Bullet Time charge up. When the second grenade comes, shoot it out of the air, kill the person throwing it, and then go into Bullet Time. Start working left to right, killing whatever you can find. Stay up and shooting constantly. Even though you will take damage, just pop pills as you are shooting so you can stay up longer. I highly recommend that you DO NOT shoot the vehicles here. With all the vehicles around, when they start exploding, the smoke gets too thick for you to actually shoot anything. It may take a few tries to do it but you're pretty safe here and can just return to your checkpoint if your Bullet Time runs out. Just don't let it make it to the cutscene.
I'm not sure what triggers the cutscene but just keep shooting enemies until it does. You have to reload but you otherwise have infinite ammo. Keep killing until the chapter ends.
