Walkthrough:
Chapter 1
Point Insertion
Wait through the G-man's little speech. You find yourself in a
passenger train car outside City 17.  Listen to Breen for storyline, or
not. I like to play a little game here called "Beat the Civil
Protection goon". Grab a suitcase, box, etc with your use key, and then
throw it at the CP's head. Fun! He'll chase you around with his riot
prod for a while- don't worry, he can't hurt you much.
Pass through the rotating door, then follow the hallways to the room
with departure/arrival times listed. Enter the caged area, go where the
CP's prompt you. You will end up in a small office where the CP leading
you reveals himself to be Barney, from HalfLife 1.
Exit through the back door, climb the ladder, then put a box in front
of the window so that you can climb out.  Follow the obvious path until
you reach the guard who knocks the soda can off the trash bin into the
floor. Pick up the can and place it in the trash. I prefer to pull it
back out afterward and lob it at the CP's skull. Sure, it earns you a
riot prod jab, but it's worth the pain.
Exit through the front door of the train station, then head right down
the street. Take the a right into an alley where you can climb a ladder
to a catwalk to pass over a fence. Continue through the alleys to a
courtyard, where a door to a building is open near some CP's standing
guard. Enter the door, then go upstairs, where a squad of CP's are
raiding an apartment. Head to the end of the hall and go up the stairs
to the next floor, where a man will be trying to get your attention.
Follow him, and start running!
Chapter 2
Red Letter Day
Guards will be after you now, so run to the end of the hall go up yet
another flight of stairs. A man will be waiting here for you to enter
before closing a door. Do this, end then follow the stairs up to the
attic.
Exit through the rend in the attic wall, and leap to the next roof.
Either skirt the gutter or run up the ramp to the next roof's gutter,
where you will have to walk a long ledge under pistol fire until you
reach an open window. Downstairs, you will meet Alyx Vance for the
first time. Cute for a pile of polygons!
Follow her into the elevator and then down the hall, where she will
open a door for you and then tell a little bit about the history of the
world since the alien invasion. Go through the soda machine cum secret
passage to the laboratory, and meet Dr. Kleiner and his de-beaked pet,
Hedy Lamar.
Watch the antics for a bit if you wish, then hit the button and slip
into your HEV suit. Comfortable and utilitarian! Dr. Kleiner wants your
assistance in sending Alyx, oblige him by fixing his blown plug and
flipping the switch. Listen to Barney's sass, then hop in for your own
trip through the teleporter. But oh no! What is this? Something going
not quite as  expected? In a teleporter machine? In Half-Life?
Unforseeable!
You'll end up on a catwalk behind a building in City 17. Avoid the
scanners and weave your way through to a door blocked off with boards.
Listen to Barney and obtain a crowbar. Deal with the boards, Freeman
style.
Cue thumping beats, cue squads of CP's firing at you while weaving
between train cars. They are mostly hiding out of reach- don't bother
with them unless you are a masochist. Just find the train car with the
ladder up, be sure to avoid the passing train,  and then leap off it to
the next car, then over the fence to a door with more boards to dispose
of.
Chapter 3
Route Kanal
Exit into a hallway where a man is being beaten by guards while a woman
screams. Beat down the CP's and get a pistol with which to smite thine
enemies. Go up the stairs and shoot the surprised enemy there. At the
bottom of the next staircase, put a few bullets in the head of the guy
at the top.  At the top of the stairs, wait for the train to come, then
leap on top of it. From there, jump to the opposite side of the
trainbed.
Blow up the CP's that appear via the handily-placed exploding barrels
near all their firing positions. Break open the doorway to the house,
then run through to the rear, where more CP's will be awaiting their
fiery dooms. Climb over the broken fence section and run toward the
alley. Crouch to enter the vent and follow it to its end. Enemies will
fire from the train across the way. They should fall after 3 or 4
headshots even on Difficult mode.
Jump down into the train bed, kill more guys, go up the stairs and
avoid the rolling exploding barrel. Keep heading up the stairs, down
the hall, and then up more stairs, killing CP's all the way. Break the
boxes blocking your way and then go down the stairs and jump down to
the train tracks. Kill the guys charging from both directions, make
sure to use the health station to refill, grab the boxes of goodies,
and then bail off the tracks into the aquifer running parallel before
the train makes you into a pancake.
Swim to the end, then climb into the abandoned boxcar and listen to
what the two characters have to say. They will provide an exit out the
back- take it. Break the wood blocking the way, then walk past a rolled
semi to watch a barnacle devour a crow.
The best way to get by a Barnacle without wasting ammo is to pick up a
junk object and toss or place it onto it's tentacle. Then pass by
unharmed.
Watch the poor humans get slaughtered by the nasty combine turret.
Assuming you don't want this to happen to you, take a quick right, stay
behind the boxes, and head into the tunnel entrance to your right.
Follow the tunnel, and you should come up behind the CP, in perfect
position to take them all out. Don't miss all the goodies around and
below the Combine turret position!
Man the turret and kill CP's if you like, but make sure to shoot the
barrel suspended on the rail to the right, in order to complete the
walkway. Then follow that walkway back over the wreckage. Watch out for
barnacles!
Keep following the tunnels past another resistance member to a room
full of water. Jump in, grab the supply boxes, and wait for the enemy
to drop exploding barrels in. Dive to the bottom until they've
exploded, then jump through the hole they blew in the tunnel grate.
Follow that tunnel to it's end, then move out into the junkyard,
watching for enemies above. Take out the bridge with the exploding
barrels at the base, then find the section of caved in tunnel with
three barely-visible barrels blocking the tiny gap, and push the barrels
to gain entry into another tunnel.
Careful, the ground is slippery and barnacles are all over the place.
Don't bother wasting ammo unless you enjoy it, just toss debris into
their line and move on.
Jump out into another aquifer, kill enemies as best you can among the
barrels being flung at you, and then climb the ladder over the fence
into the next section of water.
Climb the ramp then leap from dock to dock until you enter another
tunnel.
One of your first physics puzzles is here. Place blocks onto the
shorter end of the seesaw so that you can use the opposite side as a
ramp up to the next area.
Take the first left, and avoid the helicopter. Once you get to the
junkswamp area, start running like mad  from cover to cover, avoiding
helicopter fire. Take the left unless you really need the health to the
right. Follow the walkway up to the door, move the barrel, and enter.
Follow the hall, and make sure to go down the ladder first to get the
health before heading up toward the supply crate. Crouch at the left
end of the waterway and follow it to the end for more health, if you
need it.
Head right and then down the long slippery passage full of barnacles,
then jump the railing to the left. You will find another long slippy
passage full of barnacles. Grab the exploding barrel nearby and roll it
down the passage. Let a barnacle grab it, then shoot it a few times as
it pulls it up. A few less barnacles to deal with. Jump the railing at
the bottom to the left, then follow the hall to the doorway.
Head left out the door to the end of the catwalk. The helicopter seems
content to watch for now. Take a left into a stone hallway. Follow the
hallways through a loading screen to   a bunch of debris that must be
destroyed to move further. Do this, then continue and bust through the
barricade to another resistance member who will give you more
information.
Use your crowbar to thrash the manhacks that come crashing in, and make
sure to grab the two supply crates and the cache in the upstairs corner
before leaving.
Open a chainlink gate and destroy more manhacks.
Follow the passage further, make sure to hit the small supply room here
if you're low, then head outside briefly. Move the barrel and enter the
next door before the manhacks arrive. Close the door, and then jump
downward to the sewer. Kill the enemy that drops down and take his SMG.
Kill the rest of the enemies that appear, then detonate the barrel
blocking the lower passage. Crouch to enter the passage. Crawl to the
end and meet your first zombie. Exit and kill more Combine troops, then
jump into the giant mixer at the end of the passage.
Swim to the tunnel on the left side of the mixer pit, and follow it
down, stopping for air as necessary. Exit at the top of the water
tunnel and then follow the big pipe, killing CP's as they appear. Climb
up at the open-air end of the pipe, and then run back down the pipe to
the end of the hall.
Watch out for the steam vents here, and the barnacles nesting above it.
It's best to simply kill the barnacles before attempting to move
across. Make sure to grab the health on the ledge nearby!
Run to the end of the pipe, break the boards to the right, then drop
down and crawl under the pipe. Kill the manhack and grab the goodies.
Crawl back under the pipe and look for a vent. Drop down the vent into
the water, then swim out and climb the ladder.
The troops with the truck at the top will roll exploding barrels down
on you. Try to shoot the first one before it hits the ground, that way
they all explode on the enemy. Take the right, kill more troops, then
duck into the stone hallway. Follow it to the end, into the room with
the red lighting. Grab the supplies and then crawl into the vent. Drop
down, break the tile, and and you'll fall through onto some barrels.
Watch out, there's explosive barrels everywhere, and manhacks will be
flooding into the room soon. You can climb the incline in the corner,
and be safe from the majority of the explosions as well as having your
back to the wall for fighting manhacks. Also, up on that ledge, you can
jump from the railing to the pipe which is easier than jumping off of
the ladder to the pipe, in my opinion.
Jump from the pipe to the opposite walkway. There is a vent up here with
an item in it.
From contributor Shorty:
#I managed to get in after some messing around. It's a +15 powercell.#
Thanks Shorty!
From contributor Frimp13:
#he way to get to that vent is to pick up a barrel, stand it up
straight (by leaning it against another barrel, etc.) and place it on
top of the pipe while standing on the ledge.  It works best if you sort
of lean it up against the stone pillar.  Then go up onto the pipe via
the ladder.  Carry the barrel over to where the pipe bends and stand it
up against the ceiling beam.  Jump up onto the barrel and then from the
barrel onto the ceiling beam.  From there, leap across to the vent -
pressing crouch AFTER you jump.  There's a small power-up for your suit
in the back of the vent (kind of disappointing after all that work.)
-Frimp13#
Thanks Frimp!
Go through the door and jump down the opposite side of
the central pipe, so that you land on the ledge next to the valve. Turn
the valve, or jump down one more pipe and turn it if you can't reach.
Swim up and back into the manhack room, and then down into the area the
manhacks came from. Swim into and through the pipe.
Break all the boards at the bottom so the cable spools can float to the
top, and hop across them (using turbo if necessary) to the opposite
side then up the stairs.
Climb the ladder and run across the boards to the ledge, then drop down
into the water on the other side of the fence. The right is a dead end
with no redeeming qualities but some manhack baseball. The left will
find two soldiers rappelling down and a manhack to back them up. Head
left fast, if you reach the soldiers before they hit the ground you
won't take too much damage then you can focus on the manhacks.
Jump up onto the ledge to the left, be prepared to kill a manhack and a
scanner. Grab the supply crate, too. Head dead straight down the hall
skipping the doorway on the right for now, grab all the supplies at the
very end but watch out for the barnacle! Then go back to the door we
skipped and head inside.
Climb the ladder, grab the health, follow the half-assed walkway, grab
more supplies, then drop down.
You will exit into a pit of slime. Stay on the ledge, and head left.
Climb onto the pipe, cross, and grab the stuff from the corpse- he
won't need it anymore. And even if he did, we'd need it more than him
and have the guns to back it up.
Drop down off the pipe, and head to the door, staying carefully away
from the deadly slime. Continue on until the resistance people run
screaming about the enemy shelling them. Watch the shells that drop for
headcrabs, and remember to shoot for zombies' heads so the crabs don't
come loose after you kill the body.  Also, look out for environmental
traps like electricity and slime.
Continue until you come to a large metal cargo container crackling with
electricity. Remember not to touch live wires or the walls of the
container! And don't forget the supply crates inside. Run past the next
couple of headcrabs and zombies, then round the bend on the plank
docking to reach the mudskipper :)
Chapter 4
Water Hazard
Goof around for a while in the practice area and get good before you
open the gate and leave. It's a dangerous world out there. Note that to
pick up a supply crate on the mudskipper, you just have to run it over.
You will soon come to a small barn with a dock. You may notice the G-
Man up there. Land and investigate. You will find two zombies and a
headcrab, along with a few assorted supplies. Make sure to check the
attic.
Further down, you come to another of HL2's physics puzzles. This one is
simple. Just pick up the blue air barrels and drag them down under the
basket end of the ramp to lift it so that your mudskipper can leap the
gap. Check the tunnel to the left for more barrels.
The next area is not hard, just keep your mudskipper at full speed and
aim for the ramps. Dont worry about killing troops or collecting supply
boxes, just get through the area at the greatest speed possible unless
you enjoy killing everyone or collecting everything.
Soon you will come to broken overpass. Ignore the soldier atop it and
continue on until you reach a ladder. Moor there and climb the ladder.
Kill the soldier and enter the building. Watch another Breen movie, if
you like those, then move on to a garage containing two soldiers and a
few small siderooms containing a good amount of loot. Watch out for
manhacks as you approach the next room, they will swarm you if you're
not careful. They will be backed up by two more soldiers as well.
Stock up on grenades here, you'll need them as you move into this
killzone littered with sparse cover. Duck behind the Truck on right and
use your turbo, cause that turret can shred you fast. Get a grenade off
on the troop behind his cover and move through the door behind him.
You'll encounter 2-3 troops in here shouldn't be a problem to dispatch
even if you're out of grenades. Grab the ammo and move through the door
to the left, to a balcony. Shoot the exploding barrels to the right and
then duck back through the door and then out to the gun turret. Enemies
will be pouring out. Decimate them with the turret and then move
through the door behind them, back to the garage.
There will be 4-6 troops waiting for you behind soft cover with a
turret. Take out the cover and turret with grenades and then mop up
with SMG and pistol. Use the hanging shelves as traps by using
explosives near them and shooting them.
Exit via the way you came in, grab your mudskipper, and head out
through the now-destroyed water gate.
Things get more difficult now, with APC's firing rockets at you and
soldiers firing small arms. All you can really do is run away and
occasionally run someone over. Take turns sharp, juke missiles, and
look for hidden and natural ramps as well as the obvious ones.
Soon you will come up on an area with a lot of obstacles like fences
and hurled and wrecked vehicles. This took me a few tries on Difficult,
it is not easy. Once you get through, you end up at a little island in
the muck with a simple puzzle involving removing weights to obtain
life, armor, and ammo.
Continue onward to what appears to be a medium-sized Combine base. Take
a right and dock near the stairs at the door to the building. Head
inside to pick up a magnum and assorted ammo and health. Soon after
picking up the magnum the door in front of you will open, with troops
lined up like child molesters at a britney spears concert. Put those
fools out of their misery!
Move onward and then up a ladder. Watch out, there's an enemy at the
top of the stairs and a helicopter flying around up there waiting to
fill you with holes. Run between the boxes and kill an enemy, hopefully
before he releases the manhack, otherwise, deal with that before moving
onward. Manhacks are annoying. Kill another guy as you pass under a
woodern structure and head between the broken sections of chainlink
fence.
Look in the boxcar for supply crates and in a stock of normal crates
for a further third supply crate. Then enter the warehouse building.
This building contains 4-5 manhacks and 4-6 combine troops. As soon as
you go upstairs, 5-6 more will begin to enter, so be ready.
Head down the hallway then down the stairs, fighting 3-4 more troops as
you go, then look around the bottom of the stairs for supply crates,
health, and armor refills. Get ready to head outside!
Run ahead-right through the now-opened gate. Remember to get the supply
crate back around to the right as well if you missed it earlier. Avoid
the chopper and shoot the guard at the gate, then kill the guard at the
next gate as well. Head up the ladder into the guard post and grab one
of the guard post guns. Show the chopper the wrath of Gordon. Then open
the gate with the panel.
Run/swim back to your mudskipper and head around to the right, toward
the gate you just opened. Avoid the bombs the chopper drops, but
remember they are time based, not proximity, although running into one
will still set it off.
Eventually you will come to an area ramped-off to the right. Follow it
and take the big jump at the top, and you should land next to a large
warehouse. Head inside, park your mudskipper on the lift, and collect
stuff. Use the lift to drop you and your skipper into the goop heading
opposite the way you arrived, and then continue with your merry voyage.
Watch out for the falling tower! Exit the area via the tunnel.
You come out near a building with a machine and scaffolding on the
side. Another physics puzzle. Climb the ladder back in the tunnel then
drop down to get to the scaffolding. Pull the lever then weigh the
elevator down with the washer on the scaffolding above to lift the
ramp. Then leap!
Follow the waterways until you reach a gate manned by resistance
people. Enter the gate and dock. Go inside, check out the map, and
listen to the plan. Go back out and take a gander at your skipper's new
upgrade. Blow up the boxes blocking the gate, while you're at it.
You'll come out of the tunnel to a chopper's waiting rotors. It should
prove easy prety for your newly-acquired badass gun. Keep going till
you reach a gated compound. An enemy chuckle will sound and then groups
of  5 enemies will rush out on either side. Take them out with the
skipper gun then disembark to the right and head inside to restock.
Go back out, reboard your skipper, and drive up the ramps and past the
closed gate. Follow the waterways further, past a few guys on rickety
platforms, and you will get to a water tunnel with walkways on either
sides. Enemy troops will be tossing explosive barrels off of the
entrance into your path. Take them all out and move into the tunnel,
then over the drop-off.
Soon you will come to a fork. The path to the right has a troop, a
zombie, and several headcrabs, as well as some health.
The path to the left has a U-shaped area with troops rolling explosive
barrels down a ramp at you. Dodge right onto the shoulder to avoid the
flame wall and shoot the barrels as they appear. Shouldn't be too hard.
you'll empty out into the ooze again. Enter the tunnel.
As you come out, one of the two cargo crates has supply crates inside.
Go left around the beached ship and you'll come to a small dock in
front of a Combine building. Use your mudskipper cannon on the two
vehicles. There are supply crates on the beach nearby, and two more
inside a wrecked orange cargo container.
Check the cherry-red cargo contained for two explosive barrels.
Detonate them to open a path for your mudskipper under the dock.
Use the ramp to jump the gap and head into the tunnel.
You will end up in a rocky mudflats with an enemy base on one side.
Check near the beached ship and on top of a pipe as well as a few other
places for  supply crates. You will be assaulted by a chopper here, be
ready to take it out with your cannon.
Go to the smaller gate and find the little guard booth next to it with
a ladder leading up to it from the beach. Climb up and turn the wheel
until the gate is open. Go through the gate and climb the ladder next
to the dock.
Shoot the two guys that come running out of the door of the compound,
then open the door and kill the two inside. Make sure to raid the
shelves and use the refilling machines here.
Cross the compound to the stone gate, and climb the ladder down onto
it. Pull the Gate Override switch. Hop back into your skipper and head
back down to the stone gate. Get some running distance, and take that
log ramp through the gap in the gate, over the edge, into the pool
below.
Chapter 5
Black Mesa East
Enjoy the fall? Drive your skipper to the dock nearby and climb the
ladder on the dock marked with the HalfLife logo. Enter the doors
behind the building and listen to Dr. Mossman explain a few things. Follow
her to the elevator and then down to Dr. Eli Vance.
Meet Dr Eli and then Alyx will arive. After some bickering, she will
take you to your new toy, the gravity gun. After some practice picking
and throwing, she'll take you to meet Dog, her loyal pet.
But partway through the demonstration, something goes wrong. Follow
Alyx back through the elevator. The ceiling will crash in. Alyx will
instruct you to follow Dog. Do so, and then go through the door he
lifts for you.
Follow the passage until you reach a broken elevator. Destroy the lock
with any weapon to open the cage over the ladder, then climb it. At the
top, follow the passage to Ravenholm.
Chapter 6
"We don't go to Ravenholm..."
Head straight toward the water tower and enter the lit building to the
left. Note the proliferation of great missile weapons here, and the
crowd of zombies to use them on. Enjoy. Follow the passage through to
the outdoor area, where a holy man may be heard preaching. Watch out
for the whirling blade machine. As long as you crouch you're fine.
Zombies don't know how to crouch.
Enter the door to your left, kill the headcrab inside. Grab the health
if you need it, and grab a buzzsaw blade too for some slicin and dicin.
Check the dark nook in the corner for two more zombies and another
headcrab, then head out the door.
Kill the zombie at the end of the hall, then run down there and face a
room full of slowly-rising zombies and a whirly-blade machine. Destroy
them as you will, then exit and to a grotesque scene of charring
impaled corpses.
The Father will appear at a window in the building upstairs and speak
to you a bit. Grab the health pack behind the pillar and then the other
in front of the boarded door. Zombies will come through the door at
you. Kill them. Inside you'll find more health, some hurling weapons,
and a caged zombie to roast at your leisure.
Turn off the gas at the top of the hill with the valve in order to
pass. Alert the zombies to your presence, then run back and turn the
gas on. At the proper moment, hit the spark button and send them up in
flames. MWAHAHAHAHA!
Back at the funeral pyre, douse the flames using the gas valve so you
can enter the front door of the house the Father was speaking from.
Inside the house, first toss an exploding barrel up the stairs to take
out the three zombies. Then clear the blocked staircase of furniture
using the gravity gun and take out the three zombies and three
headcrabs you will encounter, including two of the new type.
Head back to the two green machines and climb the one with the vent at
the top. Enter the vent. When you leave the vent, make sure to get all
the supplies laying around, then head back to the first zombie flambe,
where we left the electrified corpse.
Climb the ladder, then the next few ladders, then jump across to the
ledge on the next building. Chat with Father Gregorian for a bit, then
drop down to the catwalk running back over the gas trap.
Jump in the window, then use the canisters as rockets with the grav gun
to take out the zombie and headcrabs below. Then drop through the floor
and walk out to the alley next door, where a car-dropping trap has been
rigged up. Use the trap a few times on the roaming zombies to get an
idea of how it works.
When the undead have been disposed of, walk out to the second car trap.
This one will also function as a lift to get you to the catwalks above.
Also, if you are comfortable making the jump, you can use the second
car lift to get high enough to jump over the fence marked with the
half-life symbol. Behind this fence is a room with health and ammo in
it.
Walk across the catwalks to the nearby window and enter. Gregorian will
comment again on your progress. Open the door and proceed down the hall
through a loading zone.
Watch out for the headcrab through the next door, then take a right and
open the door to see Gregorian bustin caps in a zombie.
Kill the zombie on the floor in the room with you, then exit through
the window and help Gregorian kill several more zombies and headcrabs
on the ledges outside. Use the exploding barrels below to clear the
area, then jump down and collect goodies while picking off stray
zombie.
Proceed to the ladder at the end of the area and climb up. Go all the
way down the planks and enter the roof to the left. Grab the loot,
watch out for the headcrab. Then double back and head into the roof on
the right. Kill the zombie on the floor and move into the next room.
Grab health if you need it, then get ready to fight a horde of zombies
downstairs. Objects around the room make good projectiles. Exit the
building via the downstairs.
Outside, quick zombies can be seen bounding from roof to roof. One of
them charges you immediately, so be ready. Search the surrounding area
for several zombies, some healthpacks, and ammo, then head into the
building full of washing machines. Kill a zombie in the hallway, then
another at the top of the stairs, then a third who, along with two
headcrabs, busts through some boards at the top of the stairs.
Pick up health and ammo in the room to the right, then up the next
flight of stairs we go. Two headcrabs wait at the very top, along with
a door leading outside. Circle around the left of the roof, and
Gregorian will talk to you a while before giving you a shotgun.
Brace yourself, because 3-4 quick zombies will now charge you from the
surrounding roofs. You can fight it out, or leap immediately into the
water vat across the way, then climb the ladder out. More quick zombies
will attack now, climbing rain spouts and leaping across large gaps.
Enter the room, gather the goodies, and two more quick zombies charge
when you hit the elevator button.
At the bottom of the elevator, you will meet the headcrab momma zombie.
Kill him and the quick zombie as well as a few headcrabs, and then
climb the board on top of the car over the fence.
Go right to a room with health, ammo, and a headcrab in it. Keep
following the alleyways until you enter a new, larger area with some
quick zombies leaping across the roofs. Take a left and watch out for
several zombies, headcrabs, and another headcrab zombie momma.
Enter the contruction area to the right, with the visible balcony
outside. Climb the stairs, pick up the health, and flip the lever on
the balcony outside. Jump down, run to the big building with all the
pipes on the top, and climb the stack of boxes on the right side. Jump
across to a ledge on the wall, climb the ladder, then follow the board
walkway from roof to roof until you reach the top of the big building.
Restock on health and supplies here then double back to the walkway,
where the platform should be in the middle, allowing you to cross. Jump
across, and prepare to be beset by lots of quick zombies and hurled
headcrabs. You can take this time to drop down behind the locked door
and unlock it from the other side, but that means climbing back up.
Doesn't seem worth it to me.
Jump to the fire escape on the opposite side, listen to Gregorian, and
get the health from the room inside the window. Pick up a buzzsaw and
head into the hall, slice zombies. Repeat as necessary. Make your war
forward as you do this and eventually you will get to the end of the
horde. Go down the stairs to a loading zone.
Going down the next set of stairs here takes you back toward the
alleyway where you first encounter momma headcrab zombie.
Lets go up the ladder, being wary of the three headcrabs upstairs- one
of them usually hides in the boxes. Now open the door, and step out
onto the ledge, where you will be warmly greeted by a quick zombie. Run
across the roofs to the next roof and jump down. Then run up the stairs
and along the walkway, fighting headcrabs and zombies along the way,
until you reach a door. Open the door and head upward, collecting
goodies along the way. Climb the ladder to the hatch on the roof, grab
the health and shells, and prepare to be inundated with quick zombies.
It's easiest to shoot them before they reach the top of the waterspouts
they climb. Two shotgun blasts to the head will take one down on
difficult. I managed to get through without a single on reaching the
top my second time through, so it's not an especially difficult area,
just disorienting at first. Eventually Gregorian will get the cart up
to you, and you can hop on and pull the lever to being your
(agonizingly slow) descent.
Grab the loot at the bottom of the lift, and follow Gregorian to the
graveyard and mines. Upon entering remember to use your grav gun and
the buzz blades/cinder blocks/barrels as much as possible, as there are
a LOT of zombies and not a lot of ammo here (at least on difficult). I
was able to kill them a lot faster with just grav gun and projectiles
than Gregorian could. After killing enough of them, he will lead you
further into the graveyard, until you reach a crypt where he will let
you past the door into the mine before lighting himself and the
graveyard on fire.
Approach the mineshaft with caution. You will need to drop down from
beam to beam. Drop from the last beam into the bit of walkway still
standing, and begin killing headcrabs to thin the herd a little. Make
your way over to the tunnel rafters. You will need to crouch-walk into
the tunnel on them. a couple of grenades on the explosive barrel will
clear the area and you are free to collect the health and drop down
into the next area.
Swim along through the tunnel, avoiding the barnacles, until you reach
a crosshatched fence. Jump out of the water over this and then continue
swimming until you reach a tunnel with a coal fire or something burning.
Trigger the whirly blade cart carefully, and follow it up the shaft.
Let the zombies walk into it. Exit at the top of the tunnel to a
loading screen.
Climb the stack of boxes to the halflife logo, where some grenades and
a magnum await you. Break open the semi-hidden supply crates too. Walk
out onto the train tracks, where a quick zombie will attack. Dispose of
him, then continue on to an overpass where a sniper is taking potshots
at some zombies (notice his blue laser sight). Collect all the supplies
below, and let him do the dirty work, then toss a grenade into his
little loft.
Approach the next sniper slowly, and stay out of sight. Make sure to go
under the left side of the lumber truck, and then to the left of the
next red box car after that, which contains several grenades and has a
hole in the ceiling conveniently pointing directly at the sniper
position. Nade the poor bastard and move on.
Past a few more wrecked train cars, right after the health and ammo
cache, you will find a group of Combine troops fighting a zombie. Take
out the whole lot of them.
The tracks empty out into a station, where three enemy troops await.
Two more spill out when you pick up the health and ammo laying in a
wrecked white van in the lot. Inside, surprise the three combine troops
from their flank to turn the tide for the resistance fighters. Follow
Leon inside to a console where Alyx asks you to go Nova Prospekt to
save her father.
Chapter 7
Highway 17
This chapter is mostly about driving the dune buggy, which is great,
cause the dune buggy rocks.
To start, grab health if you need it, then climb into the buggy. You
will be lifted off the platform, down to ground level, by a crane with
a magnet. Once it drops you, jump out and blast it with your grav gun
to right it, then hop back in and take off for the little road up the
hill. Follow that road to a ramp.
Turbo across the ramp and make a quick pit stop at the house to gather
supplies before heading through the tunnel to a loading screen.
Upon exiting the tunnel, take the embankment down and to the right,
then floor it across the plains, cause the antlions are gonna be on you
like flies on doody. Soon you will come to a house, with a thumper
outside. Thumpers keep antlions away, for the most part. Note that an
antlion will still sometimes jump inside the perimeter of a thumper to
attack, if you provoke it enough.
Park your buggy near the thumper and head to the basement doors of the
house. Inside, kill a couple of headcrabs, fill up on grenades from the
crate, and climb upstairs into the house. A headcrab zombie momma is
here. Kill it and collect goodies. Hop back into your trusty buggy and
party on down to the next house. Park near the thumper and head into
the barn. Pick up any goodies, and come out to face the two troopers
that should be spilling out of the house right about now. Climb the
ramp into the house, and check out the viewmaster in the window.
Back to the buggy, and another roaming trip across the plains. When you
see the next building, pull up next to the trooper truck, which is
already nice and close to the thumper. Take out the three solders with
your car's nice unlimited gun. In the barn, use the gravity gun to pull
up the supply crates.
To the Freemobile again, and then up and past a beachhead base of some
kind. Travel a ways further, then pull into the resistance camp and
follow the man in the cream shirt into the house.
Listen to Odessa drone about the use of the launcher until he hands it
to you. Then go out and help them kick some dropship ass. Just remember
to stay behind cover unless you're firing or moving for more ammo, and
don't be shy about hitting up the medics for health. Dropships take
about 8-10 rocket shots in difficult.
After beating it, search around for more ammo and health if necessary
and then drive out through the previously-closed gate onto the winding
highway. Take the right onto the grass embankment when the road ends.
Follow the grass to the NLO base, which is currently inhabited by enemy
troops and under siege by antlions, since the thumper is off.
You can either wait for the antlions to kill the troops, or try to bust
in and turn the thumper back on then take on the troops, or try to bust
in and kill them all.
My choice is usually the second. In the chaos of the battle, drive up
to the thumper, leap out of the buggy, and turn it on. Then run up the
wood ramps killing everything in sight. Grab the supply crates, then
climb the ladder, killing three more enemy troops on the way. Get over
to the crane, but first check in the red cargo container for another
supply crate. Also, keep an eye out for ammo on the way up the ladders
to the crane. Once in the crane, use it to lift your buggy up onto the
platform. You can also use it like a wrecking ball, and pick up objects
like cargo containers to use as even bigger wrecking balls. SO much fun!
Once everything is dead, knock the bridge back down in order to cross,
then assault the big garage, which contains perhaps three troops,
depending on how many you killed with the crane. Drive around behind
the building and kill two more troops. Accelerate up the ramp and
through the glass window. Haul ass up the hill to the river. Cross the
bridge ignore the gunship for now. Once you reach the traffic jam, jump
out and grab the rocket launcher on the ground. Use the rockets to
destroy the gunship. If you run out, there is a rocket box in the van
farther into the jam. Once it is cleared, use your grav gun to blast
the cars off the cliff and out of the way. There is a van halfway up
the hill with supply crates if you need more health or armor. Head to
the tunnel at the top of the hill to a loading screen.
Careening down this mountain is a blast, but be careful. The little
ball you used to play with Dog earlier is now deadly to your fast-
moving vehicle. If any Rollermines attach, jump out and pull them off
with the grav gun, then blast them into the ocean.
When you get to the bottom, stop near the house or you'll be caught in
a landslide. Fight  the four enemies that come, search the garage for
supply crates, and then head into the house.
Kill a few guys downstairs, then head upstairs and collect ammo and
supply crates. Once inside, shooting will begin in through the windows.
Run outside to engage the enemy and find four troops. Kill them and
continue.
You'll need to move a couple of cars out of the way, then kill a few
soldiers with a truck blocking the way.
When you reach a wreck of cars and a semitruck right before a bridge,
hop out and climb to the knoll and pick up the crossbow. Take out a few
guys, make sure to get the one on the billboard and the one on the
bridge.
Drive down to the energy gate and hop out of the buggy. You'll have to
walk around it for now and leave your buggy. Grab one of the exploding
barrels and come around the left side of the buildings. Wait for
enemies to appear, then toss it near the other exploding barrels and
the gas pumps to create a big explosion. Mop up the garage and house
for ammo and health.
Continue down the freeway until you get to a little cluster of
buildings arranged in a cul de sac. Stay in your car and watch the door
to the house on the right. Shoot any soldiers that come out, then jump
outa the buggy and bust in with a grenade or two and take them out.
In the next building, kill the headcrab momma zombie and then collect
all the goodies. Exit and enter the abandoned house on the cliff. Drop
down on to the path below. By dropping at the right place you can land
practically in front of the door to the bridge innards and avoid the
path altogether.
Fill up on rockets at some point here, you'll need them eventually. Be
careful climbing on the bridge underworks, I prefer to stick to the X
crossbars rather than the edges, if I can't be up on the catwalk.
Anyway, cross past all the little stations, grab health if you need it,
kill the three enemies at the third station before moving across to it.
Watch out for the  headcrab at station 1, the two headcrabs at station
four, and the supply crate to the left of station four. At the back of
station four, go down the stairs and then continue back to engage two
troops. Four more wait inside the building, along with some supply
crates. Exit via the side exit, and go around and up the ladder.  Kill
the sniper high above, then go around to the windows and kill the three
troops inside.
Go down the back stairs and clean up. Make sure to get the two supply
crates. Then go all the way up both staircases and take on the two guys
inside the energy field. You can try to kill the field before killing
the troops, but its often easier to wait for them to come to you and
then take the shield down separately.
Head downstairs and then out to the underworks of the bridge again. A
gunship has taken notice of you and will fire on you until you destroy
it, so it's best to engage it early. Work your way back to a chest of
rockets and use a simple cover/fire strategy to take it out, then cross
back to the first station at your leisure.
When you emerge, there will a mob of zombies and antlions fighting on
the path. Fight your way up to the little group of buildings and you
will encounter four troops. Kill them, and drive up to the bridge. Play
chicken with the train, but remember to turbo or you probably won't
make it ;) Veer left at the end and drive up the broken overpass into
the tunnel.
Killing zombies is fun, killing zombies with your car in the dark is
even more fun! After a bit, you'll come to a pileup. The whole thing is
laced with zombies, but is also full of good grav gun ammo. There are a
few quick zombies in the mix, too.
Watch for the small hole leading from one side room to the sealed side
room. There's good supplies inside.
Continue down the road until you see a house just off the side of the
freeway. Get off the road and kill the three soldiers guarding the
house. Head to the top floor for the health and ammo, but also watch
out for the Rollermines.
Head out and back onto the road, and continue to a roadblock. Kill the
soldiers with your Tau Cannon, but watch out for the ambush on the
other side. Stop before the pop out and be ready with your Tau Cannon.
Take them out, then head into the house for health and ammo. Blast
through the barricades and you're back on the road.
You'll soon reach yet another barricade. Hit the natural ramp at the
right edge to cruise over it, but you're boxed in by the other gate.
Prepare for dropships of troops to attack, along with some Rollermines.
Kill them all, then head into the house. Check out the battery
situation: not good. You need to find more. One is nearby on the bed,
the other is out in the junkyard in a wrecked car hood. Plug all three
in to open the gate. Continue through the gate, to a tunnel and a
loading screen.
Upon exiting the tunnel, you will arrive at a resistance camp which is
about to come under siege. Park your car in the open garage as
requested, and prepare for battle.
The squads are easy enough if you remember to use grenades and gas
tanks. On the last squad, run into the lighthouse as soon as you see
the gunship. There is a stash of rockets you can use to fight the
gunship there.
Once it is destroyed, head downstairs and then out through the secret
door opened by the resistance guy. Move as fast as you can along the
cliff edge and into the cave, to a loading screen.
Chapter 8
Sandtraps
When you come out, you'll come upon an unfortunate pair.
A man and his friend, Lazlo, who is about to be eaten by antlions. If
you didn't catch the warning, don't step on the sand. Every time you
do, it will spawn one to three antlions.
Continue through the sand. There are supple crates all over the place,
but make sure to carry large flat pieces of metal or wood with you to
walk on, or stick only areas with rock floors.
Make sure to take the first left over the smooth rock ramp, down a junk
path into a little sand cave where a antlion has killed a few
resistance and combine soldiers and hoarded their gear and supply
crates.
Also, look for the tipped over windmill that is working as a shallow
lever. Move a box to the near end and climb up to get to a network of
buildings. Lay a board across a gap to get to the red wood building
with white doors. Move a piece of metal sheeting found near the board
up against the red wood building to use it as a ramp and get on top.
Then climb up to the building above it for a supply crate.
Head up a nearby wooden ramp to another red wood building, but with no
doors. A supply crate inside with lots of armor. Leap across the ramp
to a white building and turn on the generator behind it to get a
thumper running. Enjoy the crates nearby.
Follow the trail of rocks down from the white building to a beached
ship and a cliff, each with supply crates. Then head for the ledge with
the rock path leading up, check for a few more supply crates, and then
leap off into the next area.
Here, you will battle your first mega-antlion. Just lead it around like
a bull, letting the door gunner do the shooting for you. Occasionally
use the shotgun if it gets distracted. Afterward, gain the pheropod,
and pass through the door.
Search the camp for several supply crates and loose powerups, then
follow the vorgon into the antlion pen to learn to use the pheropod.
The pheropod is very simple, having only two functions- call antlions
to you, or throw to direct the antlions to a location. After completing
the simple exercises, leave through the far exit.
Travel through the caves until you reach an industrial-sized thumper.
You'll have to shut it off in order for your antlion buddies to pass.
Climb the ladder and hit the switch. Continue to the next thumper,
and shut if off as well. Keep an eye out for the soldiers that will come
pouring out of the small bunker around the hill. Your antlions should
be able to make short work of them. Collect the two supply crates
and move on down the beach to the next thumper. The mounted gun
in the bunker up in the rocks is manned, so watch out! Remember
that the thumper itself is wide enough to provide cover from the gun.
Send your antlions up behind the bunker to take out the soldiers
hiding among the ruins. Shut off the alarm inside the bunker, and
make sure to grab the 4 supply crates scatter inside and behind the
bunker.
The next area is a little rougher. Come around the bend carefully,
because the mounted gun in the bunker in the hills is manned once
again. Use the rocks on the beach for cover as you move down the
beach, then up and around the bunker to reach it's flank. Eight to
ten troops will engage you along the way, but as long as you
continually direct your antlions toward them they should pose little
threat. Pay more attention to keeping yourself behind cover and
healthy, as the bunker gun will be firing on you the whole time.
I found it easiest to toss a grenade into the bunker once behind it.
There are only  three or four troops inside so perhaps it's a waste,
but it's so very satisfying. Collect all the supplies inside, then head
into the tunnel near the circular stone pit.
Two manhacks will attack once you reach the bend. Gravity gun
makes killing them easy. Once the red flares light, prepare for a lot
of enemy troops. There should be about ten of them. Remember
to use your pheropod to send your antlions in, then help out with a
