this code. Simply follow the IDBEHOLD command with
the letter in parentheses for the desired powerup

keys. (Leave "K" out of the code to get all the weapons,
but none of the keys)
Lets you warp to any level in Doom.
Type IDCLEV and then enter the number of the episode
you want (1,2, or 3)followed by the number for the
desired level. For example, typing IDCLEV23 starts game
play in the second episode, third level
This works the same in Doom2 but you just type in the level
like IDCLEV03 would bring you to level 3, etc...
Doom only - Use this code to turn on the "No Clipping"
mode, where you are able to walk through walls. Type

The following codes can be used at the command line to personalize the game.
After typing Doom at the Dos prompt you can type these command line

These last three are in what is known as developer mode. I use it often to
get my screen shots
While in developer mode you will see some flickering dots at the
bottom of the screen. These dots tell you how many frames per second
(fps) the game is running at. One dot is 35fps, two is 25fps, three is
17fps, and four is 14fps
Any time you are playing Doom (or Doom2) and the developer
mode is engaged, you can take a screen shot of the ongoing action by
pressing f1. Screen shots are saved in the Doom directory as PCX files.
Each screen shot you take is automatically named DOOMxxx.PCX, where xxx
will be an ascending number beginning with 000. Screen shots can be
displayed and manipulated with any paint program that
supports the PCX format such as the Paintbrush accessory
of Microsoft Windows.

The code is IDDT. Go into the map view (tab key) and type IDDT. This will bring you
the full map. Type it again and it will show you every item in the game and the direction
it is pointing in. Thanks David.
