I recommend printing this if you want to use the binds in game.DOOM 3 ADDENDUM:
1. ACCESSING THE CONSOLE IN DOOM 3
The Console can be accessed with the CTRL-ALT-TILDE (~) key. Please
note that use of the console is unsupported by Activision Customer
Support. Please do not contact Customer Support with console command
questions.
Note: For ease of use, the console can be set to open with just the
TILDE (~) key. To turn this setting on you must enter the following
command:
com_allowConsole 1
2. VOICE COMMANDS IN MULTIPLAYER
Doom 3 multiplayer has the ability to play audio chat lines in-game for
purposes of taunting, congratulating, or for team-specific requests and
instructions. In order to utilize this function, keys must be bound to
them in the console. While this feature is unsupported, we've included
a CFG file that when executed will bind the key-pad keys to those voice
commands.
It can run from the console by typing the following:
exec mp_vchat
Here is a brief description of those bindings and their functions:
GENERAL KEYS
Keypad Insert = Great game
