Dog spawns from nowhere
When you and Alyx go back to Dr. Kliener's lab via
the teleporter, Dr. Kliener shows Alyx that Dog has arrived. If
you stand at the very back of the room (in front of the green
door) and crouch, you can see underneath the door to the room
where Dog is. However, he is not there. Just as Dr. Kliener opens
the door, Dog suddenly spawns out of nowhere in the room, just
in time for him to run out.
Backless clock
When you and your squad are inside that big building
and trying to disable the "generators", you will eventually
encounter a clock that is hanging on a wall above an archway.
To find it, enter the building and go up the stairs to the right.
Go underneath the archway ahead of you, turn around, then look
up to find it. Equip your Gravity Gun and shoot it using Mouse
1. Keep shooting it until it is on the floor, with its face and
hands facing the floor (so you cannot see them). Notice that it
has no back. You will be able to see through it. You may lose
it -- to find it, crouch on the floor and look for a semi-circular
shape and shoot it with your Gravity Gun until you can see its
face and hands again.
Lamar passes through crates
When Barney turns on the lights to the room that your
Hazard Suit is in at Dr. Kliener's lab, he finds Lamar (Dr. Kliener's
pet Head Crab). She (Lamar) attacks Barney. Barney then throws
her onto the floor and she slams into some crates. Notice that
she passes through them.
Invisible Lamar
When you first meet Lamar (Dr. Kliener's pet Head Crab),
enable the impulse 101 code and shoot her with any gun.
Lamar will instantly disappear. You will see some blood on the
floor after she disappears if you shoot her with your pistol.
Alyx, Barney, and Dr. Kliener will all act as if she is still
there. Only Barney and Dr. Kliener do not look on top of the cabinet
where she is supposed to be. They will look in completely different
directions. Lamar will later return in the Teleporter room. You
can shoot her again and the same thing will happen.
Lamar passes through Dr. Kliener's leg
When you and Alyx go to Dr. Kliener's lab via the Teleporter,
Alyx bangs on the door and asks Dr. Kliener to let you out. Dr.
Kliener then opens the door holding a shotgun. You will then see
Lamar appear at Dr. Kliener's feet. However, she passes through
Dr. Kliener's right leg in the process.
Jumpy Dr. Kliener and shotgun; invincible and vanishing Lamar
When you and Alyx go to Dr. Kliener's lab via the Teleporter,
enable the noclip code and go through the door into Dr.
Kliener's lab. You will see Dr. Kliener and Lamar behind the door;
both of them not moving and a shotgun lying of the floor next
to Dr. Kliener. When the moment arrives for Dr. Kliener to open
the door, he suddenly jumps towards the door to open it, and the
shotgun suddenly jumps into his hands. If you try to shoot Lamar,
she will not die. After Lamar runs out of Alyx's view, she just
disappears around the corner (and is not actually hiding at all).
Frozen Hawaiian hula doll
When you first enter Dr. Kliener's lab, you will find
a Hawaiian hula doll on a desk with some monitors on it. If you
bash into the desk, you will make it dance. However, when you
and Alyx enter Dr. Kliener's lab again via the Teleporter and
try to make it dance again, it will not. It is completely frozen
on the spot.
Pass through Dog's arms
After you and Dog leave Dr. Kliener's lab (after the
Blazing Saddles reference), Dog waits for you to jump down
a level. While Dog waits for you, he is completely still. He will
not walk away from you when you get close to him. If you approach
his arms, you can pass through them.
Dog's wires pass through Alyx
When Dr. Kliener tells Alyx that Dog arrived at his lab several days ago and lets him out, Dog rushes out and hugs Alyx. However, you can see that one of Dog's wires attached to his arms will pass through Alyx.
Kill Alyx
In the Red Letter Day episode. when Alyx gets into the teleporter enable the noclip code. Enter her and when the teleporter goes up she says "uhh". Leave the teleporter. Look at the ground under the teleporter and you will see Alyx's body there.
Door to nothingness
After you and Dog leave Dr. Kliener's lab (after the Blazing Saddles reference), enable the noclip code and go through the drink machines blocking you from going back to the beginning of the game. Go up to the door ahead of you. Disable the noclip code and open the door. You will see that there is nothing behind it, and you can just walk into nothingness.
Fly very high
At the train station level, go up on to the platform
on the right side where the blue force field is located. When
you come up to where the trains are, you can jump onto the train.
Once on top of the train, wait for a train to come by. When it
does, jump on to it, but make sure that you just barely make it.
Once this is done, quickly turn backwards and press [Jump].
You will fly extremely high and can see the entire city from your
height. Note: It is highly recommend that you enable the god
code to avoid dying from the fall. Also try killing the combine
soldiers while up in the air.
Cloned pedestrians
Use the super-grav gun trick and go back to the d1_trainstation_01.bsp
map. You can manipulate/shoot the people standing in line. They
will remain untouched, but a clone will appear, affected by the
gun. (Screenshot)
Interrupted teleport
When you are going through the teleporter, shoot the
man when you are in the office. It will kill him, but you will
not continue to teleport.
