Version differences

Content is censored in some countries. For Australia, install the Left 4 Dead 2 - Uncensored DLC; for Germany and other regions see Low Violence/Censored Versions.

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

The game in third person.

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 back 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

Notable Workshop mods

The game has a huge variety of mods, however, what may be "better" is subjective and opinionated (so Shrek Tank won't be listed here, for example). These mods help improve the base game, though use them as your discretion.

Gameplay

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".

Notes

  1. File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/550/ in addition to or instead of this directory. The app ID (550) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
