Chapter 3:	Freeman Pontifex
==========

Go up to finally reach open air. Zoom in to the bridge to see the Combine on
the move. Then move around the barrels on the left to find the path leading
down. Go left to hit the open path full of pounders. You need to run along 
the first three pounders to avoid the endless Antlions. There are crates along
the way, but they only have health. When you reach the third one, rest inside
a small shack on the right that will protect you from the acid.

When you leave the safety of the third pounder, get out the GG as you approach
the rails in the ground. At both ends will emerge big Antlion Guards. With the 
Gravity Gun, pick up the red barrels and start tossing them, but try to focus
on just one. The sprint button will be your friend during this fight. You need
to run all over, but try to lead the guards into walls. If they charge at you,
get by a wall, and then run out of the way when they get close. When stunned
you have a little bit of time to hit them. You don't have time for grenades, 
but be sure to use any you may have in the SMG (the alt fire, press LT). You
can ignore the smaller bugs, just focus on one guard. When the first one goes
down, then go for the other with the shotgun/magnum.

*NOTE: You can go back into the pounder area for more barrels if you want.*

After Alyx and the Vort rejoin you, he will open the lift nearby, but it gets
stuck. Climb up the ladder and then take the grassy path on the right side. 
Watch out for the headcrab. Go around the pod and gently move onto the wooden
board so that it will fall away. Then you must jump the gap to reach the other
planks. When you get close, look on top of the elevator to the wooden board 
holding the hatch. Use the GG to break that piece of wood, then knock off the
metal hatch, and then drop down. Pull out the pickaxe and you're done. Press
the button to get everyone up. Then follow the path to a load point.

Proceed until you find the Pulse-Rifle with a bunch of health and dead guys.
Soon you get a bit of a scene about your next task. Move to the force-field
and wait for Alyx to open it. Go through and find a room with a large water
tank. Move the green shelf, carts, and wooden boards blocking the elevator 
shaft, then hop down. Crouch, turn on your flashlight, and move the objects
in your way. Then bust the wooden boards and hop down. 

You probably hear that creepy noise. Crawl through the hole into the dark 
room. When you move the chair from the door, the big zombie will bust through.
You should crawl back out of the room and drop a grenade behind you (press LT
on 360). The thing will crash through the wall to get to you, so maybe toss 
it another frag, then finish it off with the shotgun. 

Go through and bust the planks on the floor to get down another level. Look
on top of the elevator and get the hatch off. Jump to the other side of the
elevator (not down) and look down to see two poison headcrabs. Shoot them 
before dropping down. Go through the door in here to enter a staircase where
you find that Alyx has the sniper rifle working. Go down and through the door
at the bottom. 

In the next room, look down and quickly use the GG to grab the two crates or
else Barnacles will claim them. Then drop down and pick up a barrel. Behind 
you will be a bunch of tongues in front of a doorway. Put the barrel in one
tongue and slip by. Then break the boards blocking the path to see more 
tongues in your way. You should pick up one of the gas tanks in here and send 
it up to the Barnacles, but make sure you stand back. Cross the big plank in
the middle to get over the gap.

Watch as the torso zombie gets burned in the fire, then maybe wait for another
to so the same. Turn the valve to extinguish the flames. Go across and look
down the steps to see another zombie. Just toss down a grenade. If you want,
you don't have to, but you can open the door he was banging on to find a room
full of undead and crates. Be sure to toss in a grenade first and use the 
shotgun to mop up the survivors. Then go down the steps.

You can investigate the rumbling in the blue container; it's a fast zombie if
you get too close. Break the lock on the door and go through. Let Alyx handle
the zombies in this corridor. Crawl through a space at the end. When you 
emerge, quickly toss a grenade down the steps, then back out of the line-of-
sight of the carrier zombie at the bottom. Alyx will handle all of them if you
just want to hide in the corner, or go back through the crawlspace. 

When the coast is clear, go down the steps to find a locked door. Back away 
from it and hide behind the fence in front of the door and get your shotgun
ready for the zombies that emerge. Alyx will handle what gets up the steps, but
you can use the gas tanks to help. Then go through the doorway.

Go down the hallway and as soon as you turn the corner blast the second barrel
to take out the zombies and Barnacles. Ignore the other barrel and mop up
any remaining headcrabs. When you moved toward the boarded up doorway, have the
shotgun ready for a Zombine. Don't miss the shotgun shells in a crate behind 
the pipes, then proceed up the steps.

Go right to find just some rifle ammo. Then follow the path up a ladder. Use
the GG to blast the metal pieces covering the tops of the roof. Don't fall 
down through a hole, just make the roof clear so that Alyx can snipe some of
the undead below. 

Have your shotgun ready and drop down onto the platform standing above the 
ground. Defend this for as long as possible from the zombies that will try to
smash it down. When it does crash and you're on the ground, all heck breaks
loose. You will have zombies all over in no time. But use the saw blades on
the walls to help ease the trouble. 

After the first wave the game should save, but then you get another wave. A 
huge group will crash through the wall on one side, and more will come from
the other side. Drop some grenades, slice the Zombines, and just run around 
in circles hoping Alyx has you covered. Use the shotgun to finish up.

When all is calm, search for crates and supplies. The fence trapping one 
zombie has a crate, but you just need the GG to pull the crate over the fence.
Then follow the path from the broken wall to find the trail. 

You arrive in a dark storage room. Crawl under the shelves on the right to find
a crawlspace. You run into a fast torso at the end, and then another around
the corner. Hop up on the wooden platform and keep hopping along to get to
the other side of the room. In this closed off area you need to get up to the
top platform on the wall, but no shelves will take you there. Use the GG to 
bring a crate and set it on the lift of the forklift. Then go toward the 
driver seat and pull the lever. Quickly get on the lift as it goes up. Then 
put the crate on the side of the lift near the top platform and jump up. Break
the vent cover and crawl through. 

At the end you drop down in the radioactive waste area. Drop down through a 
hole to hit the ground level. Watch out for all the zombies in the sludge. You
can jump from ground to ground without the aid of the objects. Hop over, be 
sure to kill the Zombine when he rises, and then follow the edge around the 
pool to get through the opening in the fence. Use the barrels to kill the 
zombies that attack you behind the fence, then climb up the ladder. Stock up
on SMG ammo at the box. You will find a crate behind a fence, so just pull it
over the top with the GG as before. Then crawl under the pipes to drop down 
on the other side. 

Have your magnum ready when you move toward the next waste pool. A headcrab
carrying zombie will appear, so take him out quickly and dodge the headcrabs
he tosses. Jump to the wooden roll in the waste to reach to pipes that lead
up to a crate. Bust the crate and then jump down to the ground with the other
crate, then pull whatever fell out of the first crate with the GG. 

Now comes another fun radioactive waste puzzle. The object is to use the rolls
throughout to make yourself "bridges" to safe ground. Pull the roll across the
waste to you, and bring the one from the waste behind you. First jump on the 
car and to the first rock, then jump onto the second rock. When you jump on
the next car it will begin to sink into the waste. You can either quickly 
pull the roll from the third rock into the waste to create a platform, or you
can jump back and use all three rolls to make a moving bridge, but using the 
car is easier.

When you reach the third rock you need to quickly pull out your shotgun and 
start shooting the gas tanks in the sludge. Whatever you do, don't let the 
Zombine get close with a grenade. When all are dead, use the four rolls you
have to get to the fourth rock. Once you get there, pull out the shotgun for
more zombie fun, but Alyx should get all three.

Make your way to the fifth rock where the last trio of zombies will attack, so
use the gas tanks to kill them. Pull the crate for the sixth rock way away to
you with the GG and then get over to the ladder. Head up and up until you 
find a small shack. Go inside, but be ready for the fast zombie in here to
wake up and the Zombine outside to awake. Kill both and claim the rewards in
the room. On top of a ladder on the adjacent building is a crate with some 
health. 

Go up the slope to reach the bridge at long last. When you get to the car,
disaster strikes of course. Go to the left to find a crate, but also on this 
small walkway is a ladder. Get on top of the red railing to find a path back 
onto the middle of the bridge. It took a while, but the trick is to push all
the cars off the bridge. This will cause the thing to tip down to the side
where your car waits. When you get all the cars off, hop off the low end of
the bridge and get back up to your car. Drive it onto the see-saw bridge and
jump off the high end (you don't need to turbo, but you can).

When back on the side with your friends, collect the stuff around (look in the
dumpster) and then climb a ladder to find the button that unlocks the door.
Reunite and say your goodbyes to your Vort friend. After he opens the gate, 
hop in your ride and get going toward the light.
