hand, are effective.

=================
4.0 >Walkthrough<
=================
Here's the noticably linear walkthrough for the noticably linear story mode.


----------------
4.1 >Insecurity<
----------------
On the Tram, Barney rides through some tunnels in order to get to Securty point
C, where he will be assigned to his first task of the day. During the ride, he
can see a distinguished Scientist (Gordon Freeman) also walk onto a following
Tram. When he gets off, the door is locked! The Guard on the other side will
open it for him. Meanwhile, watch the Scientist as he passes by on his tram.
At this time, the Guard has unlocked the door for Barney to enter. Talk to him.
He'll say that the place has been all broken lately.

Go through the doors and go right. Talk to the Guard at his post. He says that
Barney cannot go through this door until he gets his sidearm and uniform on.
Go downstairs, head to the lobby, and talk to the Guard there. He knows what's
going on today. Go right and up the elevator. On the second floor, go left to
the surveillance room with three screens. These can be looked through for some
extra features to find. Go to the opposite side of the hallway and head to the
Armory, where the manager will give Barney his sidearm. In the shooting range,
there's some ammo Barney should collect, but not spend here. Return to the
elevator and lobby, and face the guard on his chair. To the left is the locker
room. Go there and collect the uniform in Barney's locker. Return to the Lobby
guy and he'll point out that an elevator has broken down. Go to where the Guard
prevented Barney to advance and he'll allow him to go through.

In a room with turbines, go up and through another door. Barney will meet up
with a Scientist reading the daily Newspaper. He'll state that the Trams are
out of order and that Barney will need to head toward the elevator through the
lower hallways. In the dark corridors, Barney should turn on the Engine and
find a switch near the door to turn the lights back on. Keep going through the
linear hike until he comes across a river. The Tram contains a guy in a Tuxedo
carrying a briefcase. Once its across, press the switch to bring down the
bridge. Advance until Barney reaches another Tram station.

The elevator's nearby. Hack the elevator console to make it work. As the three
people go down, something has gone wild in the labs across. The elevator goes
down further, and below, some very unnatural things occur. After this chain of
unfortunate events, the elevator falls down and knocks Barney unconscious.

----------------
4.2 >Duty Calls<
----------------
Barney wakes up in front of what appears to be a Houndeye eating parts of a
Guard! EW! Get up there, grab the Crowbar, and shoot those things! Smash the
boxes to find some more 9mm ammunition, and explore the area. The door is not
going to move unless the power is turned off. The source is located in a room
not too far away from here. Barney will need to smash it to allow the door to
be opened (smash all the boxes to search for more ammo first). Go through the
door.

In the room with all the puddles, avoid the water and kill all the Headcrabs in
the room. When they are all killed, go through the door to find some ammo and
another headcrab! When the room is cleared, go up the stairs to find a
Scientist who tells Barney to get out while he can. Back down at the desks,
push a chair towards the locked door. Jump on it and over the fence. Also, back
where the Scientist is, Barney can shoot the red barrels from there and open
the gate by force.

There's a lift here. Activate it and jump on it quick! When Barney approaches
the bridge, some Houndeyes will appear. Shoot them all and the Vortigaunts. To
the left is the controls to open the door to the next area. In the corridor
filled with boxes, there's some more Houndeyes waiting to pounce! To the left
is another Houndeye with a corpse. Grab the Helmet there and use the controls
to lower the busted lifts so that Barney can jump onto the boxes and to the
ladder (the first lift will require a box nearby so Barney can jump onto that).
In the damaged area is some more Vortigaunts that spawn. Shoot them to the
afterlife and go down the ladder towards the sewers.

First, go right and jump across the catwalks. Turn both wheels on the pipes to
stop the steam from blocking the way. The lower catwalk leads to a corpse with
a SPAS-12 and the notification that this way out is futile. The above catwalk
leads to a switch. Activate it so that a lift ahead will go down. It contains a
box of explosives and a few Vortigaunts. Shoot the abominations and go back to
where Barney started on this paragraph. The other way has a ladder attached to
a pipe. Go up and towards an area with Barnacles and a body of water.

Shoot the Barnacles above and go down to where the barred window is. There's a
valve in this area that will make the water rise so that Barney will be able to
advance. Collect the supplies and attack the Aliens that spawn. Another one
will appear on the bridge, destroying it. Jump down to the pipes and get
across. Here is a flooded area with lots of aliens (including Bullsquids)! In
this area is a power node that should be turned on so that Barney can go up the
lift. Now Barney is able to access the Box of explosives! Collect the ammo and
push the Box into the canal river, where it will destroy the turbines blocking
the way. Move up and listen to the Army Soldiers' conversation. It looks like
the Army isn't intending to rescue Black Mesa after all...

---------------------
4.3 >Captive Freight<
---------------------
Stupid Bush! Anyways, go up the ladder after demolishing the boxes in the room.
There's some supplies behind the two Turrets in the back of the truck. Don't
bother trying to open the gate behind the truck. However, the other gate is
not, and it leads to the only way Barney can escape! The car on the road has a
Revolver and some Armor. Continuing only leads to a squad of Soldiers that
instantly lock the door! Next to the car is a locked gate, which can be busted
with a thrust of the Crowbar. Go down the manhole.

At the bottom, defeat the Headcrabs and keep walking through the tunnels.
Sometimes, Barney will have to use a valve to advance through the airlocks. The
same applies to the hallways Barney will have to tread. Keep an eye out for any
hostile aliens. When Barney gets to a dead end with a vent, pile some boxes and
climb up. Advance through the vents.

Here's where the real fun begins. Get out of the vent and into the storage
room. Go left and collect the supplies from the dead Guard. To the left shows a
pair of Soldiers attacking someone. Kill the two of them and collect their
Guns. Talk to the Scientist the baddies attacked. He says that he and his
friend, Dr. Rosenburg, attempted to get out of the place, but got caught by the
Army. His colleague is the only chance of getting out. Collect the Medkit and
the 357 ammo in the locker and blast the Soldier that bursts in with the SPAS
-12. In the hallway, to the right, is some debris blocking an elevator. Go up
and collect the supplies at the end (Dr. Rosenburg will be needed to get to
the other side of that door). Go to the stairwell.

At the first door, go through and smash the boxes. At the end is the same squad
Barney encountered at the beginning. Use the Revolver to take them down. Once
they're killed, a Soldier will smash a window above a dump trailer. Climb up
there and show him who's boss. Then go left and through the door.

In the room, open the lock and collect the massive amount of supplies. This
station contains a big squad of Marines, and two cars. The blue one contains a
lot of Vortigaunts to distract the Soldiers if necessary. The red one contains
a Scientist. He claims that he isn't Rosenburg though. After this, a door opens
with some angry Soldiers. Blow them away and check the area for additional
resources.

The outdoor station has another nasty squad of Infantry and a Turret inside a
box. Search the area for any noticables. The red boxcar has another Scientist.
To get to him, smash the wooden objects that block the door. This one isn't
Rosenburg either. A giant door will open in front of the turret, so use it to
fire at the bad guys mercilessly! If any escape Barney's line of fire, go for
them personally. Once all soldiers are down, go through the door towards a
dangerous area. Jump into the Truck, and collect the Bazooka. Now that the
Truck's top is blown off, fire explosives at the nearby Tank. Once it is
destroyed, search the area for more Army men, and supplies. Go through the
small door.

There's a Turret to the right. Blow it off and go to the car that contains lots
of boxes. Then shoot the explosives in order to blast the door. The next area
has some hostile Soldiers. Once the whole platoon is killed, get to a control
panel that will turn the Turntable and open the door. Get to the engine in
front of the red boxcar and use it to back up. When it is at one of the docking
areas, get into the boxcar to meet Rosenburg.

Listen to his story. He says that he can manipulate the teleporation gadgets
provided so that he, Barney, and his friends can get out. First, he'll give
Barney a boost so that he can leap out of the boxcar and ambush the Marines
that have locked the two in the boxcar. Throw some Grenades at them! Once the
path is clear, Rosenburg will follow. Go through the remaining green door.

Go up the stairs and search the corridor for some foes. Rosenburg will follow
as soon as the foes are dead. Collect the supplies, and go to the staircase.
There's a few more Soldiers to dispatch. Go down the stairs to the elevator
accessed earlier. While going up, Rosenburg will complain that the Lambda team
won't be able to help their escape due to their anticipation on Gordon Freeman.
He's the protagonist of the main series.

At the end of the lift, Rosenburg will open the door. He will then talk to one
of his colleagues, Walter. The other one, Simmons, is at the main teleportation
portal. He and Rosenburg will open the portal. Rosenburg states that in order
for them to escape via teleportation, Barney will need to go to Xen and
activate a parallel device so that they will be able to calculate the
teleporation destination. When the portal opens up, jump in!

-----------------
4.4 >Focal Point<
-----------------
Barney appears in Xen, the least hospitable place ever! Blast the Houndeyes
away and go up the arc, where more Houndeyes wait. In the cavern is another
Houndeye and a spike. Quickly go through and break the debris blocking the tiny
passage.

Keep going through this maze non-stop. Once Barney is through, he will come
across a pond with some Barnacles at the ceiling and a Headcrab. Kill them all
and regenerate at the Healing Pool if needed. There's a secret down in the
depths of this pond. Get out of the room to find an area with lots of
platforms. Jump to each platform in order to get to the other side. At one
point, some Vortigaunts will spawn. At the end is some more Houndeyes.

There's another "Island" here with a healing pool. More aliens will spawn,
knocking down a pole. Climb across it and go down. Keep jumping and swimming
until Barney reaches the abandoned research camp. Nab all the supplies first,
and then tamper with the equipment so that the signal will go back to Earth.
Some aliens will spawn, so run into a cave where a Vortigaunt will get crushed
by some rocks. Climb them and run through the corridors as fast as possible!

At the end is a portal. Jump in! Barney returns to Earth with thanks from the
Scientist. Now here's the bad news; the power reserves were just enough for
Barney to go to Xen. Now he has to go down into the cellars and get another
battery to replace this one in order for an escape. Rosenburg will escort
Barney to an elevator leading to the lower areas.

--------------------
4.5 >Power Struggle<
--------------------
At the bottom, blast the Bullsquid behind the door and collect the supplies.
Set some Satchel Charges at the door, trust me. Then go up the other elevator
and see a Scientist and a Guard protecting the battery! They get ambushed by
those **mned monsters though, and the Guard gets heavily injured. Return back
to where Barney blasted the Bullsquid to find the door getting breached! Once
they get through, detonate the explosives to send out massive fireworks!

Collect the supplies from both the gore and the walls. More soldiers await
Barney, so dispatch them all. Go up the elevator and destroy the Turret. To the
left is a bridge with a waterfall of Coliant. A Grenadier pops up and fires a
Grenade at Barney! After dodging the explosive, shoot him down along with the
pair of Marines across the bridge. A Shotgun Grunt is behind them in a small
room. A Marine and a Commando are in the room to the right. Collect the
supplies and ambush the Marine that's using the radio. The Grating leads to a
vent that leads to some supplies, including some Snarks. Return back and go
through the path leading to the next area.

The TNT wire is broken, but that doesn't mean it can't be used! Collect the
supplies here and grab a barrel. Attach it to the broken segment of the wire
and activate the TNT! This will blow up the door. Attack the Vortigaunts that
spawn here, and go up the ladder to find some Headcrabs. Collect the supplies
and activate the Coolant pump. Then go down the elevator to find another
Headcrab. At the bottom of the pool, arrange the barrels so that it lines
across the bridge parts. Return back, turning the cooliant pumps back.

At the other end is some Houndeyes. If Barney touches the pool of Coolant,
he'll be ripped to shreds! Run across the bridge of barrels and fend off the
aliens. Move through the corridors, blasting the Aliens, and notice the two
Soldiers shooting wildly at some Vortigaunts. At the top is a Vortiguant
Soldier. Blow it away and move through the door, dodging the Headcrabs as
Barney advances up the stairs. Eventually, he'll come across the generator
controls. Kill the Bullsquid and turn both turbines on. Return back to the area
where Barney last fought the Marines and go to where the Grenadier had ambushed
Barney. Use the switch to raise the bridge to access the other side. Annihilate
the Vortigaunts and talk to the injured Guard. This is the battery needed to
get out of here! He moves out of the way and dies. Put the battery into the
charging station and then transfer it to Rosenburg. Return back to the main
Lab.

---------------------
4.6 >A Leap Of Faith<
---------------------
Rosenburg congratulates Barney and then leads him back to the teleporter. This
time, Barney will be in the control room. First, activate the main power
switch. In the process, the coolant pipes will bust! Go to the switch at the
catwalk and turn the wheel. Two Houndeyes will spawn, so take them down!
Resume turning the wheel until the meter remains at the green. When Rosenburg
tells Barney to press the Damping Locks system, do it! Walter goes through
first, then Simmons, and then Rosenburg himself. He sets the equipment to
automatically restart for Barney to go through. In the process, Soldiers have
found the site and are going to assault this lab! When the door nearby
collapses, kill the two men, and resume observing the equipment. Activate the
Damping Locks and run through! Dodge the Soldiers' gunfire and make it to the
other side!

Barney appears at the exit of Black Mesa. Rosenburg is glad to see Barney to
make it, but he seems to appear glowing green. Barney suddenly teleports to
another set of Xen platforms, and then to a familiar enviroment, observing two
Soldiers carrying away an unconscious Gordon Freeman away. He then teleports
back to the exit, and Rosenburg is relieved that Barney didn't get into a
permanent teleportaion paradox (A temporal harmonic refulx to be exact).
Anyhow, the four drive off to a happy ending!
