Follow Freeman: Item room
You will hear the metal device where you get two people to follow you. After it is done, you will see a room to go through. You can find items there, but be careful; sometimes you may die. Save the game before entering it.
Getting past turrets and other dangerous enemies
When you need to run a long way in front of you and you have some objects with you (for example, a non-explosive barrel), if you have the gravity gun, pick it up. Use it as cover and run (while facing the enemy) to the other side. Then if possible, shoot the barrel at the enemy. Note: Make sure there are no more that one enemy while doing this. Also make sure that the object is indestructible, and most importantly, look at the enemy and see if you can kill him or it with one shot.
When you get the jeep, use turbo towards a wall. Press [Y] to get out before you hit the wall. If done correctly, when the jeep flips you will also flip. Note: You may get hurt as well.
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).
Hedy Lamarr was a famous Austrian actor in the U.S. from the 1930's through the 1950's. Mel Brooks later claimed that Hedy Lamarr tried to sue the producers for the "Hedly Lamarr" jokes. Dr. Kliener's Headcrab was actually names after the "one and only Hedy Lamarr".
Glitch: Clone Alyx
Later in the game when you are fighting alongside Alyx, at one point you will encounter a door where she tells you to go on without her, while she heads up to the communications room to unlock doors for you. Push her into the corner left of the door, then run in and watch it close behind you. As the next area is loading, she appears next to you. This clone does not talk, and is not always there. However, later when both of you fight a group of soldiers, there are two of them.
Glitch: Anticitizen One: Get on top of stairwell
After Dog attacks the dropship and and it drives off, go to the bent down fence and jump over it. Walk down a few steps and on your right is an open door. Go in it and to your left you will see a stairwell blocked by a couch and debris that cannot be moved. Crouch jump over the couch and go up the stairwell. You might want to bring a box with you so that you can put it on the ground in front of you then jump on top of it and make longer jumps.
Glitch: Highway 17: Edge of world
Immediately after the Combine outpost with the crane, you will jump a gap in the buggy and get attacked by a gunship. There is a crate full of rockets in the van in the middle of the road you can use to shoot it down. Clear the road with the gravity gun and drive the buggy through. After passing two more telephone poles, there is an opening on the left with another broken-down van and a rock structure on top of the hill that vaguely resembles Stonehenge. This van has three crates with medkits inside if you need them. Drive the buggy past the van and straight at the rock formation. It should climb the wall and allow you to walk to (or off) the edge of the world. Note: You will die if you walk off. Also, there are some invisible walls as soon as you get up there, but you can travel a number of miles along the ridge (but no farther along).
