You can play all the Half-Life levels that Gordon Freeman
went through as Adrion Shepard, but in the lab none of the scientists
will talk to you.
Approach the Boss of Opposing Force to hear backwards audio composed of the phrase "To win the game you must kill me Randy Pitchford" when played correctly. Randy Pitchford is the leader of the development team at Gearbox Software.
Get a gun at the beginning of the level
At the beginning of the level where you reach the security
guard, find a chair. It is easily moved. Move it to the door that
he will open for you, and get him to open it. Slide the chair
in between the doors, and it will not close. This may take a few
tries. Go out, take the crowbar, charge it up until you reach
the same security guard, and hit him until he explodes. Then,
get his pistol with the laser sight and continue the game.
When you are about to finish the "package"
and are near to going into "Worlds Collide", use the
Trans Locator's secondary trigger (which will teleport you into
Xen). You will end up in a small cave overlooking a massive healing
pool with two Bullsquids also wanting to enter it. To kill them
quickly, shoot them with the Desert Eagle. To resume the game,
run through the cave until you find a Teleporter Ball.
Enable cheat mode, then use the impulse 76 code
to activate the Grunt-O-Matic. A message to start a new game in
order for it to work will appear. If you want to continue where
you currently are, just quicksave, then quickload the game. Once
you have quickloaded, type in the code again to spawn a Grunt.
Note: You must have the /noclip code on before you spawn
the grunt because he will be spawned close to you. If this is
not done, a message stating that the monster spawned is stuck
in a wall may appear and the game will end. Do not spawn the Grunt
in a closed position or the same message will appear. The Grunt
you spawn will see you as a hostile. To have more fun, use the
/notarget code and spawn a number of grunts to do your
alien hunting. The Grunts you spawn will look like the Grunts
from the original Half-Life.
Fun with spawning
Enable cheat mode, then use the entities code
to get a list of the creatures in the location you are currently
in. Usually, when you try to spawn a creature, you have to use
the noclip code to levitate in the air and spawn the creature
nowhere near any objects. If a part of a spawned creature is spawned
within a wall, ceiling, or another creature, the game crashes.
However, if you enable the developer 0 code, the game continues
even if a spawned creature is stuck, but the creature has yellow
dots around it. Also, bind the spawn commands to unused keyboard
keys; for example bind X "impulse 76" or bind
y "give monster_scientist". The impluse 76
code works everywhere, and the hostile grunts created with it
are easy to place where you want them; as they appear in front
of you, rather than above. Now, enable the noclip code
and fly around pressing the bound keys. Watch as Barney's Aliens
and Grunts battle it out while Scientists run around being slaughtered.
Set health or damage values of player weapons and enemies in single player mode
Type sk_ at the console window and repeatedly
press [Tab] to cycle through the values. The sk_plr_
values are for the player's weapons, while other values are for
enemies and health/shield chargers. The 1, 2, and 3 at the end
of the syntax corresponds to the difficulty settings easy, normal,
and hard. Set their values accordingly. Enter a number, a space
after the syntax, then type restart to confirm the changes.
For example, sk_plr_rpg1 99999 makes the rocket launcher
in easy mode inflict 99999 damage with a blast radius that wipes
out everything in the level.
Killing Gordon Freeman
Go to the map named "of3a1". This is the
map where you see Freeman running into the teleporter. Follow
him into that same teleporter. After the map is done loading,
you will see yourself falling. Normally, if you let yourself fall
the game will restart at map "of3a1". However, if you
enable the /noclip and go to the nearest platform in front
of you, Gordon Freeman will appear. Gordon just stands there with
no weapons, and wears silver sunglasses. It takes some time to
kill him with just bullets -- try grenades or a very powerful
weapon. Alternately, you can go to this location enabling the
map of3a1b code.

Successfully complete the game and wait until the credits are over. After the screen turns black, enable the brightness 9999999999999 code to see Shepard.
Redo the sniper course
During boot camp, shoot the trainer and you will start
again at the beginning of the course.
Give any gun the magnification of a sniper rifle
Save with the gun you want to be magnified. Then, switch to the sniper rifle and turn on the scope. While the scope is on, load the previous save.
Blue screen of death
Find the computer running Windows in the room where you meet Otis for the first time. Use its keyboard five times and the computer will crash to the Windows blue screen of death.
Vortigaunts on the Hazard Course
After getting the Displacer on Xen, use the secondary
fire before you go through the portal to Earth. You will be warped
to the Crouch-Jump section of the Hazard Course, where one Vortigaunt
will attack the holographic instructor. On the other side of the
room is a second Vortigaunt and a shotgun. The portal exit is
in a corner of the observation room.
Hidden programmer message
At the end of the game while G-man is talking to you in the helicopter, enable the chase_active 1 code to go into third person view. Then, look up through the roof of the helicopter. Printed on the sky will be a hidden programmer message which reads, "Hack hack hack, all day long. Hack hack hack, while a sing this song." (referring to the fact that you will be currently cheating at this moment).
- Get to the part of the first level after the crash where a zombie throws a scientist through a window. Run around the zombie and enter the lab to find a computer with an ultrasound image. That ultrasound image is of the unborn son of Randy Pitchford, the lead developer.
- Use the self-teleporting alternate fire mode of the Displacer immediately after getting that weapon while still on Xen. You will be transported back to the hazard course on Earth. Examine the bulletin board on the wall to see a picture developer Rob Heironimus.
- While in the "Boot Camp" level, enable the /noclip code. Pass through the floor then to reach a hidden room with the message "DMM 1999", which is a reference to David Michael Mertz who developed this level.
- At the start of the "Boot Camp" level, examine the names on the boxes beside the beds. They are the names of various developers.
James Bond reference
Play the "Vicarious Reality". After Walter's hologram talks about barnacles, you will enter a dark hallway with glass containers holding various aliens. The containers are labeled with an ID number. All are intact, except for the one labeled "007", who has escaped.
Enable the brightness 9999999999999 code and go to map of3a4. After the part where you save the scientist in the clean suit and he lets you through the first locked door, there will be a room with three fish tanks. The middle one will be cracked open. Climb up through it and into the dark crawlspace with all the Xen monsters in it. On the walls will be the Valve corporation printing.
Valve, Steam, and Gearbox references
Go to map of4a4. This is the map with the Pit Worm.
Notice that in order to flush the radioactive waste, which kills
the worm, you must first complete several tasks. These include
opening the Steam vents, the Valves, and activating the Gearbox.
These are the names of the major corporations which created the
