Level 11 - Keegan

You start on a turret, and the bulk of the enemies are up above through the hole in the street. Kill them, feel free to use slo-mo, and you can explode the tanker truck. Then focus shifts to your left. All I can say is avoid shooting Keegan as he slowly moves over, and use slo-mo. When the armored soldiers show up aim for their heads.

After that, move up to Keegan, use the button to crawl under, and follow the light. Move on until you reach the third set of tracks, where a save point will trigger. Jump up to the next station and through the gate an assassin will strike, so be ready and you can use the gate as a funnel. Hop onto the next platform, grab the armor, and in the next area two will attack one after the other. Then in the ticket booth on the left is an intel.

*NOTE: The ninjas here seem more prone to leap at you, so just know to keep your distance.*

Go up the escalator and kill the two assassins that show up. Move up to the right to some grenades on newspaper stands and just wait for the two ninjas to show up, both from below. Then go right and down some escalators for a reflex injector and armor. Then go back up and push over the vending machine by the gate to get through. Go down to the fourth tracks and there is an intel on the platform and armor on the rubble if you need it for any reason.

*NOTE: Don't melee the Heavy Replicas, doesn't work.*

Head down the tunnel as a ninja flees, and in the next area you fight two heavy Replicas, an armored one, and then two more heavies; feel free to use a pulse on the armored Replica, and get his Hammerhead if your Assault Rifle is almost out of ammo. Another heavy in the corridor, and then about three more on the nearby surroundings, not including the two more shortly after. What you need to be most aware of are any exploding barrels or power generators that will cause you much harm.

Move past them to the left where you hit another two heavies from above, and then maybe one more. That should be all for this area, so feel free to drop your Hammerhead for ASP ammo, and there's an armor in the corner by the rails of the raised area.

Move along and in the next area you'll see Keegan. Go over to where he was and flip the switch, then kill the ghost to your right. Shoot more when you see them and move down the steps and go right to get down. Go around the area and into the corridor to quickly get out of this ghost zone.

On the tracks you'll find an intel in the second train. Pick up some supplies and continue straight through the door and past another for more, including armor. Then come back and down the steps will be a save point. In the watery room are three Replicas, one that falls from above. Then you have about five more in total in the rest of this area, including above. Swing around the room and go up the steps as you fight, and that will be it.

Move along and climb up the ladder to reach another station. There are about four enemies in here, and you can either go up and take cover atop the steps or to into the booth to you right for the armor. There are also a few health shots around the stairs, as well as a Hammerhead under the walkway. Go through the train on the left and about three Heavies will appear on the walkway, one after the other, so either use what's left of your sniper rifle or the hammer. Head into the corner and flip the switch, then use your pulse gun on the trio that walks onto the tracks, and aim for the armored Replica.

Hop down and swap your Hammerhead or near-empty Sniper Rifle for a Laser gun. Move up the tracks and go through the hole and crawl through the next. Pick up the intel and move through a door to see a bus. Hop over the rail and stop as the bus falls, then go around and down the tracks; notice the color going gray. Through the door you will encounter the non-harmful ghosts, so hop into the train, turn around, and then proceed up. Pick up the armor and the rifle to your left; I had the missile launcher, laser, pulse, and assault rifle.

Equip your laser if you want to test it out, but I kinda think it's trash, but either way you'll be out of ammo so swap it for an auto shotgun after the fight. There are about six enemies here, and if you don't take up point inside the snack bar they will. Again, swap the laser for a shotgun and move on. Through the door you can open a gate on a fence for armor.

In the next area just blast the first few enemies, then use a pulse round on the armored Replica neardy. Two more heavies emerge from a door around the corner, so you can mine that if you want. There's health in the booth and hammer ammo on the wall if you need either. In front of the door is armor and more ammo, so get those. Go through and out into the next area.

Around the right you can hop onto the tracks, and when you move down two soldiers drop, but hide by the wall to the right as a train speeds down and will take them out. There are however three more enemies around the building, so handle them. There's ammo on a table and up the steps is an intel item at the back and armor, but save the armor until you look over the top of the train and kill the two soldiers that appear. Grab the armor and hop on top of the train to get over, and there is one enemy who runs out the door. Proceed to see Keegan to your right and move over the rubble to end the level.
