Enter the door on the left and make your way into the storage room in the far corner of the next room. Inside you’ll find a Custom Weapon, ammo, Throwing Knives, Claymore Mines, Grenades and Filters . Return through the previous door and climb the makeshift ramp of broken cement to climb up to the bridge above.

Section 01: Main Deck

As you climb, you will notice that the enemies will be tagged for you with red holograms. There is an achievement/trophy for this level ‘Rain Man’ that asks us to make our way through the level without killing anything and this is much easier than it sounds. There are a few watchmen and a demon lurking around for most of the level and the watchmen will only attack you if they notice you. Thankfully they are usually busy fighting with one another or chewing on corpses to bother you though. As long as you stick to shadows and crouch-walk around them, this should not be too difficult to obtain. The walkthrough will tell you how to do it anyway!

From the top of the ramp move forward and wait for the two watchmen in front to separate. Once will head to the left and patrol up and down the bridge whilst the other will start munching on the corpse in front and slightly to the right. Crouch and sneak between the puddle in the centre of the bridge and the watchmen chewing on the corpse. Once past the watchman, move around the large debris pile on the right. Hug the debris pile and follow it all the way around to the opposite side. Wait for the watchman here to look away and sneak along the edge of the hole in the bridge to the left to get past him.

Near the end of the pit, go down the ramp on the left to access a lower level of the bridge. In the small room here you will earn a Morality Point and also find a pair of corpses that you can plunder for tonnes of goodies including: Ammo, Filters, Claymore Mines , a Grenade and a Custom Weapon . Return back up the ramp and continue left.

When you reach the walled area, the game will point out the enemies to you once again. Once more there are several watchmen and a demon in the next area. Wait a few moments for them to get into their positions and then move up. From the end of the walled area, sneak between the watchman feeding on the body in front and the pillar to his left and keep walking straight into the next walled area.

As you work your way through here, look out for an opening on the left next to the flaming barrel. Inside you will find Diary Note [Note 1/1] on the desk. You can also loot the safe on the floor for +10 Military Grade Rounds , ammo and Grenades . The lockers near the door also contain ammo and +5 Military Grade Rounds .

Exit back to the bridge and follow the path to the left. Climb to the top of the escalator. Approach the top slowly and again wait 10-20 seconds for the watchmen to get into their positions before climbing to the top.

Section 02: Upper Deck

As soon as you reach the top, note the watchman to your right feeding, another at the window looking outside against the right wall and a third on the ticket gate opposite the top of the escalator who is also feeding. As you start, move immediately to the left and follow the shadows along the wall here. You should be able to follow the wall all the way around to the ticket gate and pop out and around to the left after getting through without being spotted.

Now we are back out on the bridge again. Note that during this segment, you should pay particular attention to the shadows on the bridge. There is some lightning or some other external light source that will illuminate parts of the area, but there is also a shadowy path available. So take this when able!

Continue along the left side of the bridge, turning the corner and cutting back to the right when you are forced to do so. Edge up to the end of the wall and look around to the left. Wait for the watchman to jump up on the edge of the bridge and look out over the water. When he does, quickly sneak around the corner but stick as closely as possible to the wall until you are able to re-enter the shadows. Note the hanging watchman on the roof and be sure to stay crouched as you go through the shadows beneath him.

As you reach the left hand side of the bridge, turn around the pillar to the right and wait until everything goes dark again. When you judge it safe to do so, work your way along the passage here, keeping an eye out for a path through the debris on the left. Going through here will place you outside a walled area with a red light source. Wait for the watchman here to enter the hole in the bridge to the right. When he is gone, loot the corpses on the wall for a Filter and enter the room on the left. Loot the corpses here for ammo and Filters and climb the ladder to the next area.

Upon exiting the hatch, you’ll hear a radio transmission warning of nosalises in the area. Huzzah! We want to work our way up the bridge towards the flickering blue light on the left. Loot the body here for Filters . Continue past this and wait for the nosalis in the area ahead to start feeding. Sneak past it and up the concrete ramp. Interact with the hook at the end here and DO NOT shoot anything as you ride across the gap. As you approach the afar side a scene will play.

When you regain control, go to the back of the area and enter the door here. Continue through the set path here, through the train car and into the tunnel beyond to complete the mission.
