Hidden pumpkins

Set the system date to October 31. After you are ambushed by Hunters and Combine at a big house, drive along the road. Near where the supply cache is found, you will see an old truck. Go up to it, and there will be lots of pumpkins lying on the ground.

Lost reference

When you enter the White Forest base, you meet a Vortigaunt in a lab coat named Uriah. When you first enter the room where you meet Uriah, there is a gas tank against the back wall. Behind that tank is a small room with a computer that has a sequence of numbers on it. This is a reference to the TV show Lost that Gabe Newell added due to the fact that he and the creator of Lost were close friends.

Completing Chamber 18 easier

At the end of the advanced map for Chamber 18, you will have the same raised platforms as you did in the normal one except now after you leave the lower one, it falls into the toxic water. This forces you to be more precise with your portal jumps. However, you can get past this easily. Do the platform jumping as usual, but if you miss, just land on the platform you came out of. You should be able to fire an opposite color portal at the wall where you entered this area, allowing you to go back to the start. All the platforms rise again, and the portal is still where you left it. You can now fall into the pit again and be able to portal jump to the next ledge. This take longer but does not require precise timing.

Box head pictures

On the level where you get the companion cube after you run past the energy balls and are in the room with the three elevators, there are two doors leading to a catcher and a platform that is pushed out of the wall. Walk up to the platform that is pushed out. Crouch behind it, and walk through the opening. On the left hand side are a group of pictures of people with boxes for heads and hearts around them.

Using cheats and earning achievements

If the "sv_cheats 1" code is enabled, achievements are disabled; however, there is a way around this. There are a few command strings that can be bind to keys which allow you to enable or disable God mode when desired, get all equipment such as weapons, plus the better portal gun. To do this, use the bind [key] "sv_cheats 1; wait; god; wait; wait; wait; sv_cheats 0" console command. For God mode, use the bind [key] "sv_cheats 1; wait; Impulse 101; wait; wait; wait; sv_cheats 0" console command.
