Part 6

Master Half-Life 2's Part 6 with our detailed walkthrough. Learn strategies for sewer navigation, barnacle encounters, and the tricky seesaw puzzle.

Walkthrough:

1. Between sewer pipes #1 and #2, collect the 6 health packs (POS). Exit pipe #1, turn right, and sprint past the container. Aim for the left edge of the crate, then the corner of the bulkhead and trailer hitch. Swing around the trailer hitch towards the yellow car trunk. Jump onto the car's doors, then over a board, and drop down. Run through the framing and sprint to the sewer opening on the right.
2. Crouch at the entrance (EP), move into the second barrel from the left. Use the crowbar (KB) to shove the barrel forward; it will likely be grabbed by a barnacle. Stand, strafe left to the tunnel wall for cover, and slide down faster. Turn to face the wall to go left past the corner.
3. Grab an explosive barrel (EB) and face the ramp with numerous barnacles. Move to the top right of the ramp along the wall. Toss the EB along the wall and down the ramp. Fire one shot while the EB is in transit and a second when the barnacle grabs it, setting it afire. The barrel explosion should clear the path.
4. Slide down the ramp as the barrel is consumed. Continue to the end of the pipe. Grab any ammo (MKs) you need. At the pipe opening, while crouched, press crouch again to stand as you drop into the water, allowing for faster underwater movement.
5. When navigating the ramp and platforms, sprint and jump over conspicuous gaps. Be aware that falling through small gaps can lead back to the water, exposing you to more enemy fire.
6. Seesaw Puzzle to Big Long Horizontal Pipe: Go to the bottom then left around the barrier. Stay left of the water channel's center to avoid flaming EBs and a collapsing platform. When at the grated barrier between sewer canal sides #1 and #2, surface for air. Climb the ladder at the far right corner of the barrier and bulkhead. Run/jump to the left end of the platform on side #2. Swim down, forward, and clockwise around the walkway (Wkwy) piling. Rise for air under the walkway to replenish air and suit power.
7. About 30 feet from the walkway's end, look to your 11:00 for a section angled into the water. Swim down and over to this angled walkway ramp to avoid gunfire.
8. At the top of the ramp, sprint diagonally up-slope to your 1:00. If you haven't bumped into the ammo, you'll pass over it. Climbing the left side of the ramp offers minimal cover. Note the
