You'll find yourself in a baggage area. Hop off the conveyor belt and take cover at the U section. From there, clean out any enemies you can reach and then climb over the conveyor belt to the other side. Move forward and clear enemies out of here. Go up towards the room at the back and take cover behind some bags. Look up to the catwalk behind you to find two enemies shooting at you. Just be patient and take them out. When they are dead, head up the stairs in the small room to get to the catwalk.
On the catwalk, check left for two enemies. Kill them and move towards where they were. Shoot Dodge down the stairs and kill the the two enemies on the catwalk to your right. There may also be an enemy directly in front of you on the catwalk. Kill him while you are prone. Once all the enemies are dead, move along the catwalk to the right and Shoot Dodge when you see the two cops appear in the room. Before going through the door, try to find the part of the Golden Grenade Launcher on a cage above the conveyor belt. You will have to vault over a railing to get to it. Also check the side room of the control room to find the second part of the Golden Grenade Launcher. Go through the double red doors.
In the hallway, Shoot Dodge across the hall to the other side and take out the cop at the top of the stairs. From here, take out the cop that appears and make your way up the stairs. There will be another cop that appears at the end of the hallway around a corner to the right. Kill him and then inspect the office just to the left of him to find some pain killers. Move around the right corner and down the hallway. Shoot Dodge as the cop comes around the left corner and watch for another cop on the right corner.
Go through the doors at the end to enter a locker room. You'll find some Pain Killers in a locker and the last part of the Golden Grenade Launcher in one of the shower stalls. Check the bathroom stall next to it to find Anders the Ex-Cop though he'll only appear if you found him the previous two times. Exit the back of the locker room and down the hall. Go through the small maintenance area into a bathroom. At the back of the bathroom will be a medicine cabinet with pain killers. Exit the bathroom.
*Achievement: Echoes of the Past
You'll enter a terminal with plenty of armed enemies. Kill the two UFE on the right side by the white store and then make your way up the left side towards the seating area. Use liberal amounts of Shoot Dodge to move around and shoot here because the chairs are perfect height to jump over and conceal you. Move up the left side and kill the four or so enemies here. Also make sure to watch the bridge over the middle for more enemies. Once you've clear out this side, move across under the bridge to the right side and some stairs.
Climb the stairs and kill the enemies on the bridge. Cross the bridge and kill the two enemies on the far side of the upper level. When you get across the bridge, take a left so you move back across the seating area below. At the end will be part of the Golden RPD. Move back along this side of the upper level. There will be barriers along the railing that you can use for cover. Use these and make sure you watch your left side. Kill as many UFE as you can and then when you get to a point where there's another bridge across. Use that for cover. Kill the numerous UFE on the stairs (about 3) and below you (about 5). Make sure to check the lower level behind you for more enemies. Slowly make your way down the stairs looking for stragglers. Before leaving, head back over to the seating section and in the corner not far from the shutters leading out will be part of the Golden RPD.
Once everything is clear, open the shutter at the back of the lower level by using the flashing green button there. Once you are through, three enemies will appear running towards you. One Bullet Time should be able to take them all down. There is an empty stall to your left that one of the enemies likes to take cover behind. If you check behind there, you should find some pain killers. Go across and approach the escalators from the right side. Make your way down the stairs/escalators by Shoot Dodging down. There will be a couple of enemies on the way down.
Once you reach the bottom, you'll be attacked by several enemies and the lights will go out. Work your way up by weaving from side to side and Shoot Dodging frequently. Move to end of the room and reactivate the trams. Use the room as a safe point to fight from. They'll throw lots of smoke at you but just wait for the smoke to pass so you can see. Kill the six or so enemies from this room. When you exit the room, four to six more enemies will appear. Kill them and watch out for enemies still on the tram. Once you've cleared them all out, Max will automatically board the tram.
On the tram, just shoot the enemies as they pass. They won't be able to flank you so you should be able to kill them from safety until a group of four or so enemies drops down from a chopper. They'll drop smoke all over the place but you can mostly just shoot through the smoke and you'll probably hit people since it's such a narrow area. Kill enemies and work your way up the train. It's a straight line so they still won't be able to flank you, allowing you to almost just blind fire through the entire thing.
Once you've killed them all, you'll change trains. You may want to stay prone and use Bullet Time if you have it to clear out the roughly four enemies on the tram. Make sure to grab the pain killers from the cabinet on the wall up and to the right. At the end of the very last car of the tram, you will also find the last part of the Golden RPD. Make sure you get them before the tram reaches the station.
*Achievement: A License to Kill
When you regain control, you'll have to fight some more of the UFE. Don't move too far forward or you'll instantly die. Shoot the enemies and watch for Becker to shoot grenades at you. Whenever he does, shoot it out of the sky. The bags that you are taking cover behind also move to left so don't be shy about moving. All the way to the right and left will be ammo and pain killers for you to use and occasionally, a bag will be broken and you'll get more. You have to be patient and just take out all the UFE to win this fight. After you've cleared them all out, you'll take out Becker in style.
You'll be standing over Becker at this point but don't shoot him. If you wait for him to just die without shooting him, you'll get an achievement.
*Achievement: You Push a Man Too Far
You'll pick up his weapon and then chase after Victor. There's another achievement here for destroying everything on the runway. Ignore the group of men on the right side and wait for the four jeeps to come out onto the runway. Destroy these four jeeps, then the chopper. After a little bit, you'll pass cop cars. Shoot these two cop cars and then you'll see two more cop cars ahead. Destroy these two. A jeep will appear from the left side. Destroy that. Now that you've destroyed everything else (4 jeeps, a chopper, four cop cars, and another jeep), destroy the tank/apc vehicle. You'll come up behind Victor's plane. Shoot the two engines on the back to destroy the plane. Once you do, enjoy the ending!
