The following CONSOLE VARIABLES are made available (replace the # sign with a number),
in-game help is available by typing the "LISTVAR" command at the console:

"MOTIONTRACKERSPEED" - allows the player to speed up/slow down the pulse rate of 
                       the Marine's motion tracker (range from 0-16, default is 1).

"TIMESCALE #" - change the rate at which time flows in the game, e.g. "TIMESCALE 0.5"
                will make time pass at half the normal speed. For those interested, 
                the "JohnWooMode" cheat uses this effect dynamically, so that time 
                passes slower the more action is happening on screen.

"WIREFRAMEMODE #" - display the environment and/or characters using wireframe graphics.
"DOPPLERSHIFT #"  - enable/disable the Doppler shifting on the Alien player's sounds.
"SKY_RED #"       - change the red component in a sky.
"SKY_GREEN #"     - change the green component in a sky.
"SKY_BLUE #"      - change the blue component in a sky.
"LEANSCALE #"     - change the amount the camera tilts when side-stepping.
