Part 5

Strafe left past the corner, locate the explosive barrel (EB) at the top of the stairs. If it is on fire, shoot it once; if not, shoot it three times to kill the enemy (POS) behind it.

Sprint up the stairs, stop at the weapon cache (WD), then sprint through the next room to the hallway (Hlwy).

An enemy (POS) will appear along the hallway, preferably near the EB. Another will appear from the stairs past the EB.

Pass by the two enemies, take their ammunition, and proceed to a narrow walkway (Wkwy) above and beside the tracks.

Jump left, drop to the tracks, then sprint left past the supply crates (SCs).

Note: At this pace, the train often passes early. Enemies appearing down track may not be run over.

In Half-Life 2: Update (HL2ud), enemies on the tracks will shoot about halfway between the drop to the water and the rebel freight container. They may stop at the security station (SS) not visible from track level. Stay left, close to the bulkhead, to minimize hits.

Locate the opening in the fence and drop into the water. Sprint and swim along the bulkhead to avoid gunfire from enemies (BGs) charging from your 12:00 along the tracks.

Reach a freight container, locate the ladder, climb it, then drop through the opening on the roof.

Exit the freight car, avoiding the barnacles (creatures that hang from ceilings with long tongues and sharp teeth). If snagged, do not waste ammo; kill it with a melee attack (KB).

When you reach the wooden barrier after the pallet, go to the third vertical board from the left. Crouch and repeatedly hit (hammer) the two bottom horizontal boards attached to it, then the vertical board. It takes 8 smacks for the three boards.

Crouch under the barrier, then stand and run to and under the overturned train car. Pull out your pistol and turn on your flashlight (FL on) when passing the greenish mobile office with a single window.

A rebel is trapped by two enemies (POS) at the end of a grated sewer line.

Begin sprinting to the open sewer line just after passing the trapped rebel. Stay close to the sewer line to minimize damage from the two enemies further along the line and high up on the concrete platform.

Quickly enter the sewer line, turn left, and take a couple of steps forward. Stop, zoom, and target heads. The two enemies should drop with 3-4 rounds each. The civilian dies regardless.

Continue to the dark room, grab the items, then climb up and out.

Note: A game trick allows climbing the nose of a blue van up against the XP Wkwy to safety, but this is only possible after eliminating all enemies in the area. This would avoid conflict but result in missing supplies. The area can contain up to 10 enemies (BGs), 2-3 probes, and an armored personnel carrier (APC) with rockets.

Turn 180 degrees and shoot 3 rounds into the explosive barrel (EB) on the platform; this kills two unseen enemies (MGT POS).

Turn right and shoot 3 rounds into the elevated EB on the long, narrow concrete walkway (Wkwy).

Reload as you swing clockwise around the debris to the walkway, then sprint at the enemy (POS). Aim for the head and chest until he drops.

Reload while sprinting past him to the end of the walkway. Jump over the 1-2 enemies (usually 2) and continue along the "S" turns to safety.

Note: The number of enemies (POS) activated from the path at the end of the long narrow walkway can vary (1-4). Sprinting the entire length usually results in encountering 1-2 enemies that can be jumped over or run past. Ignore the Lambda cache to save time and kill the barnacle further along the path with one melee attack (KB). No damage is received from the barnacle or the fall.

To exit the sewer drain safely and quickly: save your game first. Move to about 5 feet from the end of the pipe. Press strafe left and forward; you will rise slightly inside the pipe. Turn the mouse right to face the leading outside corner of the platform in front of the next pipe opening, then look up. Press jump as you near the right side end of the pipe you are in. This leap will land you on the leading edge of the platform's corner, facing the exit point (EP) to the sewer box.

Pull the melee weapon (KB) as you approach the barnacle blocking your passage. Run, jump up, and swing your weapon; 3 swings maximum are needed to connect and be released.

Continue past the person in the pipe and run into the next pipe. Exit the pipe to the right, jump, and look up to reach the leading edge of the concrete platform and the next exit point (EP).

Jump to and melee (KB) the supply crate (SC) to the right in the tank. Swim to and melee (KB) the SC to the left. Remain in the corner and above water.

Look up to the damaged street-level sewer grate until all explosive barrels (EBs) have been dropped. Count to 5, then sink to the bottom for safety.

Turn to face the experience point (XP), and after the explosions, swim up and jump to the XP ledge. Run through the damaged grate to and past the elbow of the pipe to avoid gunfire damage.

Note: If you attempt to detonate any EBs, either the grate covering the pipe is not destroyed, or the game will not let you jump out of the water to the ledge.

This event can be stressful when first learning it. Killing everyone in the area without destroying the bridge can be done to practice the maneuver. After practicing 8-9 times and understanding the steps, proceed.
