In “Doom 3”, the long awaited sequel to “Doom II”, there are at your finger tips the ability to use cheat codes. All you have to do is hit the control, alt, and tilde (that’s the one next to the 1 key) and type in any one of certain codes. There is a code to allow you to just hit the tilde key. Some of these codes include:
Enter in this code only when you want to kill yourself.
give weapon (you must specify what weapon you want)
Like you might have guessed, you have the ability to get any weapon in the game, before you are supposed to find it in the game.
This is probably the most helpful code in the game. It allows you to be immortal, to allow you to kill all your enemies, without dying.
This is another important code, as you will be able to get every single weapon the game has to offer, and give you full health and armor. Which makes this code better than the code that you have to specify the weapon you want or asking for ammo or armor.
Give keys/ give pda
These two codes will give you either the keys/pdas for the level you are in (this is the give pda code) or for the entire game (give keys).
In the game, you can also look at some of the technical information; things like graphics card info and framerate. You can also quit the game, set how fast you move, and set how high you can jump. You can also unlock another mode of the game called Nightmare Mode.
There are many other codes, but these are the basic codes throughout the game that allow you to beat the game, if you cannot do so otherwise. For other codes (and what you are supposed to enter in), there are sites that have all of that information waiting for you.
