Start the game with one of the following command line parameters to activate the corresponding feature.

After enabling cheat mode, enter sv_cheats 1 at the console window.

Enable the map d3_citadel_03.bsp code. Once you get the super gravity gun, enable the changelevel <map name> code to go to the desired level. Then, enable the give weapon_physcannon code.

When you are on top of the dam at the end of the "Water Hazard" chapter, you can see a town with destroyed buildings under the sunset in the distance. This town is most likely Ravenholm, considering the type of buildings and its relative location in comparison to Black Mesa East.

On the first level when the combine guard (who turns out to be Barney in disguise) tells you to follow him, do as he says. While you are walking down the corridor, look through the small gap in the first door you come across. You will see a man sitting in a chair, that has blood splattered on the floor underneath it that says, "There has to be some sort of mistake. I got a standard relocation coupon juts like everybody else." A combine guard who is in there with him will then walk up to the door and close the shutter.

This cheat will allow you to "hang up" combine or zombies. You will need the crossbow and a lot of ammunition. Enable the notarget code to be undetected and find a combine or zombie. Position them against a wall. By shooting the designated spot (arm, head, leg, etc.), they will stick to the wall, if close enough. Also, if you shoot a weird part, like the bone in the leg, they will sometimes spasm.

To reload faster with the shotgun, .357 magnum, or any other weapon with a slow reload time, tap Q (change to last weapon out) twice quickly. You should then have a full clip. Note: You must fire with your other weapon. You can then fire and reload at the same time.

When Alyx goes into the room left of the elevator, quickly follow her in or open the door. In there you can hear Alyx say some things or watch the chefs prepare lunch in the kitchen (as seen going down in the elevator).

When you start the Sands Trap map, you will find some rocks. Someone will tell you not to step on the sand because a creature will attack. You will have to jump on the rocks. When the rock ends and only sand remains, use your gravity gun. Use it to place a door or wooden piece in the sand and stand on it. Then, place another object in front of it. Jump on it, remove the first object, and place it in front. Continue to do this until you reach rock again and the creature will not appear.

When you teleport to Dr. Kliener's lab from Nova Prospekt, you will meet up with Dog and go out and find Barney. Do not follow Dog out of the lab yet; wait until Dr. Kliener and Alyx start talking about getting another headcrab to replace Lamar (Dr. Kliener's pet headcrab). After Alyx suggests that he gets another headcrab, he replies, "There is only one heady." In the movie Blazing Saddles, the villain's name is Headly Lamar (whom is called Heady Lamar by some of the characters).

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.
