Hints
Glitch: Move without the zombie bull
Enter the "impulse 101" code in the console window at the point where you are taken by a zombie bull in a little carriage you cannot escape from. Kill the bull with a powerful weapon. After the bull is dead, you are still moving without a bull taking you.
Alternate "Half-Life
Type "map c0a0" at the console window. You will start on Half-Life with the Half-Life: They Hunger weapons instead of the normal weapons. Some of the enemies are also different. For example, Gman is now the Sheriff. The Scientists are now civilians. Barney looks different, and the head crab zombies are now zombies from Half-Life: They Hunger. When you are playing in this state, the game autosaves when it touches a autosave trigger. The voices are the same. For example, the endgame level on Half-Life with Gman is the Sheriff, but Gman's voice plays on the Sheriff. Note: The Houndeyes on Half-Life are now zombie dogs, however they still use the Houndeye weapon that produces an electric field.
Enabling the console window
At the main menu, select "Configurations"< then "Controls". Find the sentence "Use voice communication" then set "V" as the key to bind it to. When you display the console window, you can now type on it.
Glitch: Stuck in police station
Go upstairs towards the three doors. When the lights turn off, use your flashlight and quickly go down the stairs into where you shot the orange buttons. If done correctly, you will hear a hit noise on you then the screen will turn black for a few seconds. The screen will return and you can see again. When you try to go back upstairs, you still do not get caught; you will have to restart to continue.
