- You'll start the level by falling into a chamber filled
with sewage. The airlock is sealed, but if you look up, you'll see the familar figure of
the G-Man overlooking the area.
- Soon after, the airlock will conveniently open, with a
BullSquid behind it. Kill the squid, open the airlock and move on.
- Avoid the slime on the other side of the door and climb
the ladder. You'll arrive at the ugly scene of a small squad of dead soldiers.
- Grab all the weapons/ammo you can and continue until
you find "Black Mesa Waste Processing Area 3". Prepare to find something
extremely nasty - the Pit Worm. (yike!)
- When you first open the door, try and distract the Worm
by shooting him in the eye, which will stun him briefly. When you have an opening, jump
down to the first ledge and to the right. Take out the aliens you find there and round the
bend to a broken ramp and another alien.
- At the bottom of the ramp you'll find a locked door.
Back under the broken ramp you'll find some crates and a small vent opening.
Climb in the vent and you'll emerge at a small control
room overlooking the Pit Worm. In the middle of the room is a panel marked "Flush
Toxic Waste", and two switches labeled (appropriately enough) "Gearbox" and
"Valve". You need to light up both these panels before you can activate the
flush control, but you've got some hoops to jump through first.
- Exit the control room via the door marked
"02". Flipping the switch will close the door behind you, and open the door in
front of you.
- Head around the bend, across the lower walkway in front
of the pit worm, and down the long ladder. More stubby aliens abound, use the shotgun to
dump them. You'll come to another sewage chamber loaded with crates.
- Hop over the crates to the other side, and around the
bend to a small lift. Ride the lift up and continue around the bend to a small room
overlooking the sewage chamber. Press the button there and watch as the walls in the
chamber close together and crush the boxes.
- Run back around and down the lift to the now-narrow
garbage chamber. There's a vent in the floor.
Break the grate and drop way down into the sewage. You'll
eventually make your way to an override switched marked "Gearbox". Hit the
switch and hit the road -- the room will start to flood with sewage.
- Head back the way you came and ride out the tide as the
sewage rises. You'll eventually be able to float back up and climb up the vent you dropped
down through. Retrace your steps all the way back to the main control room overlooking the
pit worm -- the "Gearbox" light should now be on. Now you need to turn the
"Valve" light.
- Head out the door marked "03". You'll
encounter a few aliens and climb upward until you arrive at another ledge to the right of
the pit worm. On this ledge is a switch marked "Steam Vent". Hit the switch and
get out of harm's way as quick as you can.
- The last part is a little tricky. You'll need to make
your way to the ledge to the left of the pit worm and turn the pressure valve. The only
way there is to use the barnacle to latch on the organic matter above it, swinging
perilously in front of the pit worm in the process. Try and hit the worm in the eye,
distract him for a moment, and make your move.
Once you open the pressure valve, drop down onto the
ledge and get back to the main control room as quick as you can. Head back into the
control room, where both the Gearbox and Valve lights should be on. Hit the switch and
flush the big fella.
- Once the area is cleared, it's possible to climb around
and jump to the far walkway from either of the side ledges. However, you can just make
your way up the ladders to the main control panel overlooking the area, use the bridge
control, and leisurely stroll across into the next episode.
