Essential improvements
Launch parameters
To learn how to add launch parameters, see Launch options.
Useful launch parameters
Parameter | Description |
---|---|
-w X -h Y |
Sets screen resolution (or window resolution if using -window). Example: -w 1920 -h 1080 .
|
-refresh X |
Sets your screen refresh-rate (Hz). Example: -refresh 60 .
|
-noborder -window |
Launches the game in a borderless fullscreen window (i.e. very alt-tab friendly). This may result in a minor performance loss. If you experience stuttering, disable Windows Aero. |
-novid |
Skip intro videos |
-autoconfig |
Restores video and performance settings to default for the current hardware detected. Ignores settings inside any .cfg files until this parameter is removed. |
+mat_motion_blur_percent_of_screen_max 0 |
Removes motion blur. |
Low Violence/Censored Versions
- Due to censorship laws in countries such as Australia and Germany, versions of the game sold in these regions have no dismemberment, blood spatter, corpses, burning and more.
- For Australia, install the Left 4 Dead 2 - Uncensored DLC; for Germany and other regions, follow the steps below.

Split-screen without bezels
- L4D2 split-screen mode was meant to be played on a single 4:3 or 16:9 screen. If you have a different setup then, the image could not entirely fit the monitor(s).
- L4D2's file which is going to be edited is packed. Minimal hex editing knowledge is required.

Console commands
- Games running on the Source engine can utilize Source Engine Console Commands for various tasks.[1]
Instructions |
---|
- You can also have the console open by default on launch by following this guide:
Instructions |
---|
Creating your own CFG (to run multiple console commands together)
A CFG is a file that contains a list of commands that when run will attempt to execute them all
Open up a text editor such as notepad and type in all the commands you want separating each with a ;
When done save the file as filename.cfg in <path-to-game>\left4dead2\cfg\
. To run the cfg file, open the console during the game and type in exec filename.cfg
If you want the CFG file to run automatically, name it autoexec.cfg
Launch options
- View this Steam Support Article regarding launch options as well as the relevant Valve Developer wiki page for further information and a list of useful Source engine launch options.
Instructions |
---|
Third person support
Input these 5 commands in the console.
c_thirdpersonshoulderaimdist 360 c_thirdpersonshoulderdist 90 c_thirdpersonshoulderheight 0 c_thirdpersonshoulderoffset 20 bind "F10" "thirdpersonshoulder"
Alternate third person which places the player in the center under the crosshair and raises the camera higher.
c_thirdpersonshoulderaimdist 1000 c_thirdpersonshoulderdist 115 c_thirdpersonshoulderheight 15 c_thirdpersonshoulderoffset 0
Pressing F10 will toggle between first and third person. You will have a greater FOV.
Some warnings:
- Some cutscene intros will be angled incorrectly.
- You will see a weird inaccurate weapon shadow.
- The crosshair will be slightly off-center. You can mess around with the "cam_idealyaw" function to correct this. This isn't usually a hindrance anyway.
- Flashlight glows may be seen at your character's back.
- When survivors heal you, their animations will look glitchy.
- The camera may occasionally see through walls and objects.
- The shotgun will sound very quiet.
- The motion blur for the fire axe and possibly other melee weapons may look ridiculous. Here's a mod to remove melee motion blur.
- Switching between first and third person in-game may cause the HUD to disappear.
- Dying and entering new areas may revert it to first person.
Useful split-screen commands
Since Split-screen mode in Left 4 Dead 2 isn't officially supported, there are multiple important key settings which aren't immediately available.
Command | Description | |
---|---|---|
connect_splitscreen localhost [ip-address] 2 | Connect to a LAN or Internet server. Direct connections must be allowed | |
[cmd/cmd2] jointeam (2/3) | Assign selected player (cmd) to either survivor or infected team | |
ss_map <map-name> [realism/survival/versus/mutation# | Play the selected map in the desired mode | |
ss_splitmode (0/1/2) | Toggle horizontal and vertical screen split (0 is auto selection) | |
z_difficulty (Easy/Normal/Hard/Impossible) | Change game difficulty | |
setinfo name Max | Change player 1 name | |
name2 Tony | Change player 2 name |
Chat with controller
If you play using a controller and want to use the chat (Y) online, you must open the 360controller.cfg file and make it "//unbindall".
