Once the patch has been installed, simply run AvP as normal

 (or by adding "-debug" to the command line or shortcut to

 access the DEBUG mode features listed below). 



* Music CD/Frame Rate Issue

Some players reported loss of frame rate if Disc 2 was not

 in their CD drive while playing the game. This situation

 has been resolved and the presence of a non-music CD (or

 absence of a CD) in the drive will no longer cause frame

 rate glitches. 



* Single-Player Save Game

Players may now save a game at any time within an episode

 by accessing the 'Save Game' option from the in-game

 PAUSE MENU (press ESC while playing). Also, a previously

 saved game can be loaded from either the MAIN MENU or,

 again, the in-game PAUSE MENU. 



Each USER PROFILE has eight save slots associated with it

 for use throughout the entire game. There are a limited

 number of saves allowed per episode, dependent on the

 episode's difficulty level - 8 saves are allowed on

 TRAINING, 4 on REALISTIC and just 2 saves on DIRECTOR'S

 CUT. 



There are also some new console commands related to this

 feature: "QUICKSAVE"/"QUICKLOAD" which always save/load

 to/from the first save slot. "SAVE #"/"LOAD #" (# is a

 number from 1-8) which save/load to/from slot number #.

 "SAVESLEFT" displays how many saves the player has

 remaining in the current level at the current

 difficulty. This number is also displayed any time a

 game is saved or loaded. 



As with all other console commands, these may be bound

 to keys of the players' choosing for ease of use (e.g.

 "BIND F6 QUICKSAVE") will save the current game to the

 first save slot every time it is pressed until no more

 saves are allowed. 



* Normal Console Commands and Variables

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:

* "MOTIONTRACKERVOLUME" - this is set at its maximum

 of 1.0 by default, the volume of the tracker can be

 reduced by changing this number (e.g. to 0.75 or 0.5).

* "CROUCHMODE" - this new console command allows

 players to change the Aliens crouch/crawl to a toggle

 on/off key by typing "CROUCHMODE 1" at the console.

 "CROUCHMODE 0" changes back to the default setting.

 * Debugging Console Commands and Variables 

Advanced users may now access some of the game's

 internal debugging commands (which include features

 such as immortality) by running the game with the

 command line option "-debug" (e.g. "AVP.exe -debug"). 



In this mode Multiplayer is not available, levels will

 not be flagged as completed, and no new official cheat

 modes will become available. This basically means that

 players can examine a level to which they already have

 access with invulnerability, infinite weapons, etc.

 but can't open up any new game levels or features. 



The following CONSOLE COMMANDS are made available by

 this option, in-game help is available by typing in

 "LISTCMD" at the console: 



* "GOD" - makes the player immortal: player will still

 take damage, but will not die when they reach zero

 health.

* "GIVEALLWEAPONS" - self-explanatory.

* "SHOWFPS" - displays the current frame-rate per

 second on-screen.

* "SHOWPOLYCOUNT" - displays the number of rendered

 polygons per frame on-screen.

* "LIGHT" - creates a light source near the player.

 Repeated use makes a brighter and brighter light.





Bot console commands: 



* "ALIENBOT" - creates an Alien in front of the player.

* "MARINEBOT #" - creates a Marine (or civilian) of type #.

* "PREDOBOT #" - creates a Predator of type #.

* "PREDALIENBOT" - creates a Predator-Alien.

* "PRAETORIANBOT" - creates a Praetorian Alien.

* "XENOBORG" - creates a Xenoborg.



Note: creating bots may cause crashes and unexpected game

 behaviour. For a bot to be created its model must exist

 in the current level; however, the models may be forced

 to be loaded through a command line option. Add "-l"

 followed by a list of letters corresponding to the

 characters you want to load: 



'a' Alien

'm' Marine

'p' Predator

'c' Civilian

'x' Xenoborg

't' Praetorian

'r' Predator-Alien



e.g. "AvP.exe -lxc -debug" will cause both the Civilian

 and the Xenoborg models to be loaded (in addition to any

 characters that would get loaded for the level anyway).

Note that all the letters must be in lower case, and that

 "-l" on its own will still cause the Alien to be loaded. 



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.
