Left 4 Dead: The Sacrifice – DLC for L4D and L4D2

Valve will release new down-loadable content (DLC) called “The Sacrifice” for Left 4 Dead and Left 4 Dead 2 on October 5th. This DLC will be free for PC gamers!

“The Sacrifice” is a prequel to “The Passing” and includes the original Left 4 Dead survivors as they fight their way south. The Sacrifice campaign will be playable in Campaign, Versus, and Survival modes. There will also be a new finale where players have to decide who will sacrifice themselves so that the other survivors may live.

Left 4 Dead 2 players will get to play The Sacrifice with L4D2 Special Infected and weapons, as well as being able to play in Scavange mode. L4D2 players will also get the “No Mercy” campaign from L4D1 which, again, will be played with the L4d1 survivors.

The Sacrifice also boasts five new achievements.

Personally, I am really looking forward to playing “No Mercy” on L4D2!

Left 4 Dead: SourceMod – Linux Installation

Why would you want SourceMod on your Left 4 Dead server?

Well it can help you administer your server in game and you can also install additional plugins with it. This is what it looks like in game …

Installation consists of copying files to your server so you will need ftp or SSH access to your server. Before you do this you will need to confirm your Steam ID for use later – simply join a server and then open the console and then type the following and hit enter:


The result will give you your Steam ID. Copy and paste it from the console and save it for later.

Next download Metamod to your computer and extract the files. Copy the addons folder to your left4dead folder on your server. On my server this is /home/user/hlds/l4d/left4dead.

Now you need to generate a vdf file – choose Left4Dead as the game type and leave the gamefolder blank to download the correct file (click Generate Metamod VDF). Upload this file to the addons folder on your server. On my server this is /home/user/hlds/l4d/left4dead/addons.

Next download SourceMod and extract the files. Copy the contents of your addons folder to the addons folder on the server. On my server this is /home/user/hlds/l4d/left4dead/addons. Copy the contents of the cfg folder to the cfg folder on the server. On my server this is /home/sxl4d/user/l4d/left4dead/cfg.

Now we just need to grant ourselves some admin rights by editing the addons/sourcemod/configs/admins_simple.ini file. On my server this is /home/user/hlds/l4d/left4dead/addons/sourcemod/configs/admins_simple.ini.

At the bottom of the file just add the following line where the Steam ID is the one you saved earlier:

"Steam ID" "bcdefghijklmn"

The Steam ID specifies a player and the next field specifies permissions as per the following table:

Simply reboot the server and you are good to go – connect to your server, open the console and type the following to view the in-game admin menu:

Thanks to KingJulian on this thread for many of these details …

Left 4 Dead: Connect to Private Dedicated Server through a Lobby

Well I have tried to do this on and off for a little while now and found a post by MaxRabbit that works for me.

My server config is pretty bare at this point:


hostname “l4d”
rcon_password “*************”
mp_disable_autokick 1
sv_voiceenable 1
sv_allow_lobby_connect_only 1
sv_region 1
log on
sv_clearhinthistory 0

Server start script:

./srcds_run l4d -secure -maxplayers 4 +hostport 27015 +map l4d_hospital01_apartment +exec server.cfg +sv_lan 0

To connect from a Lobby this is what you do …

First launch L4D and open up the console and type:

sv_cheats 1
ms_force_dedicated_server x:y

Here x is your WAN IP address and y is the game port (i use 27015).

Close the console and then set your lobby options as normal and the lobby will connect directly to your server!

I am not sure why the sv_search_key way of achieving the same end is not working for me but this will do just fine …

Left 4 Dead – Remote Rcon with HLSW

Need to rcon your Left 4 Dead server remotely? Half Life Server Watch (HLSW) is just what you need …

The current version of HLSW is v1.3.0.6b and it runs on Windows 2000 and XP (see HLSW system requirements).

Once it is installed you will need to register an email address and password.

Once HLSW is running simply enter the IP of your server with the port:

Type in the Rcon password and click Test. You should see Status: OK.

Click the Console tab and then type in your Rcon command in the field above and then click Send.

And there you have it! A really nice way to administer your server without having to connect a game client to it … as you can see (below) HLSW also gives you a nice summary of your server details too:

Left 4 Dead – Steam Group Server Settings

Aside from setting a password with the sv_password cvar in your server.cfg there is another way to make your server private, and that is to associate it with a “steam group”.

The advantage of this method is that you can invite players to your steam group and only those players will be able to play on the server – they will also see steam group servers when the game loads (so your server should be easy to join).

So the first step is to create a steam group. Once this is created the group admin (the person who created the group) will need to click on Admin Options and then Edit group profile to get the steam group ID.

Once you have the steam group ID you can edit you server.cfg as follows, (where ###### is your steam group ID):

sv_allow_lobby_connect_only 0sv_steamgroup ######sv_steamgroup_exclusive 1

Then just invite your friends to the steam group and everyone should see your server listed in-game just like this:

Left 4 Dead: MOTD Banners

Wanna customize your Message of the Day (MOTD) and Host Banners in Left4Dead? Well, here’s how to do it …

Originally I followed this guide but I ran into issues with the host banner which displayed html code rather than the image that it pointed to.

In the above screen you can see my customized host and MOTD banners along with the names of the files that control which images you see – host.txt for the host banner and motd.txt for the MOTD banner. These files are located in the /hlds/l4d/left4dead directory on your server.

Now the images that you select will be resized depending on the screen resolution of the players connecting to your server. So I made my images the following sizes (which should support a resolution of 1920 x 1080:

host banner – 605 x 121

MOTD banner – 1076 x 538

So I created both of my banners as .jpg files and uploaded them to photobucket.

Next we need to look at the html template that we need that will point to the images that we uploaded.

<head><title>Left 4 Dead 411</title></head>
<body style=”margin:0px;padding:1px;background:#000000;”>
<img src=”URL for host or banner image” style=”width:100%;height:100%;” />

Copy and paste this into two new files named host.html and motd.html – just make sure that you change the “URL for host or banner image” part according to your URLs for the host or banner images on photobucket.

Upload host.html and motd.html to some webspace that allows public access – I used Sitesled to host mine for free!

On the server you just need to edit host.txt to contain the URL to your hosted host.html file and then edit motd.txt to point to your motd.html URL.

Now in theory you should be able to put the contents of the .html files that we created directly into the host.txt and motd.txt files on your server and have it work – but I found that (for whatever reason) the host banner simply would not work – it displayed html code instead of the banner image. That is why I hosted mine as .html files – and once I did that everything worked.

The only additional issue that I had is that the motd image seems to be resized smaller and then streched slightly (rather than being viewed at its native size) at higher reolsutions – so my advice (if you experience this issue) is to keep your text fairly large so that your MOTD does not look bad.

So here you can see what the host banner looks like in game by pressing the Tab key.

Left 4 Dead: Stuttering Gameplay on AMD Dual Core Systems

I just built a new PC for Left4DEad with an AMD Athlon 64 X2 5200+ processor. I loaded XP Pro SP2 and immediately encountered a severe stuttering problem playing L4D.

L4D was completely unplayable …

So I installed the AMD Dual Core Optimizer and hoped that this would fix the issue – but alas it did not.

The solution that I found was to disable Multicore Rendering in the Video Options as follows:

Let’s hope that there is a permanent fix from Valve soon!

Left 4 Dead – Private Dedicated Ubuntu Server 8.1

The purpose of this guide is to create a private server that a community can be built round as the current matchmaking system deployed by Valve otherwise makes this impossible (as the lobby system will connect you to any public and available server out there).

Note: a dedicated server will be installed on either on a dedicated physical machine or in a virtual machine with dedicated resources, and should be configured with a static ip address [either in the networking configuration or via a DHCP assignment in your router]. I have my server running in a virtual machine …

The first thing that we need to do is download Ubuntu Server 8.1 [click on the tab for the Server edition and then select a download location to download the .iso file].

If you are installing a Virtual Machine boot from the .iso, press F4 on the first screen and select “Install a minimal virtual machine” – this will install version 8.1 of Ubuntu JeOS. Otherwise install a vanilla installation of Ubuntu Server on your box. The first two pages of this guide will show you step by step how to install Ubuntu Server (we will assume that the account for the Ubuntu installation is “l4d” and not administrator).

Note: For my virtual machine I set aside 10Gb of disk space – you may be able to get away with less, but as you can see Ubuntu JeOS and Left 4 Dead occupy almost 3 Gb on /dev/sda1:

Now that we have the preliminaries taken care of let’s update the installation:

sudo apt-get update

Upgrade the install:

sudo apt-get upgrade

Install SSH for remote management:

sudo apt-get install openssh-server

Install Wget so that we can download a necessary file:

sudo apt-get install wget

Create a directory for the Left 4 Dead installation and then cd into the new directory:

mkdir hldscd hlds

Download the hldsupdatetool:

wget http://www.steampowered.com/download/hldsupdatetool.bin

Make the hldsupdatetool executable:

chmod +x hldsupdatetool.bin

Run the hldsupdatetool:


Type yes to the agreement and then click enter to continue.

Make Steam executable:

chmod +x steam

Run Steam to download the Left 4 Dead files:

./steam -command update -game l4d_full -dir /home/l4d/hlds

Note: you will most likely be prompted to run the last command again as the first time it runs it will update steam and not install Left 4 Dead.

Left 4 Dead files will now install to /home/l4d/hlds/l4d\left4dead\ – this may take some time, so you may want to make a few cups of tea or something …

Once the download is complete we need to create a server configuration file [server.cfg] and a script to run the server with particular parameters.

Create a file called server.cfg and copy it [using SSH if necessary] to /home/l4d/hlds/l4d/left4dead/cfg.

Your server.cfg should look something like this:

hostname "Left 4 Dead"
rcon_password "myrconpassword"
sv_allow_lobby_connect_only 0
sv_password "mypassword"

Change the hostname to whatever you want. The rcon password is for remote administration of Left 4 Dead when the server is running. sv_allow_lobby_connect_only 0 allows for players to connect directly to your server without using the Left 4 Dead lobby system. sv_password sets a password for gamers to play on your server.

Now create a file called autoexec.cfg (in the same folder as server.cfg):

z_difficulty normal

z_difficulty normal sets the default difficulty of the server to normal – you can set this to easy, normal, hard, or impossible.

Next we will create a script to run the game server as follows:

cd /home/l4d/hlds/l4d
./srcds_run l4d -autoupdate -console -maxplayers 8 + sv_lan 0 +hostip 
xx.xx.xx.xx +ip xx.xx.xx.xx +hostport 27015 +exec server.cfg +map 

Save the script as “startl4dserver.sh” and upload it to the home directory of the server.

-console: This will display a console that you can type commands into.

-game left4dead: This specifies that the server will run Left 4 Dead.

-maxplayers 8: This will specify the maximum number of players the server will allow, setting it to 8 should allow you to use versus mode, otherwise set it to 4 for survivors only gameplay.

-autoupdate: This will make the server check and update to the latest version when you launch it but this needs a manual fix to work properly.

+hostip: where xx.xx.xx.xx is your WAN address.

+ip: where xx.xx.xx.xx is the static LAN address configured earlier.

-port 27015: This will specify the port for the server to run on [27015 is the default port]. +sv_lan 0: This will force the server to run on the internet instead of just on a lan.

+map l4d_hospital01_apartment: This will specify the map that the server will start with [and must be configured]. You will find all the available map names on your server here: /home/l4d/hlds/l4d/left4dead/maps

At this point you can run the server as follows:


To connect to the server from your (LAN) gaming machine you will need to enable the “Developer Console” in the game options as follows: At the main menu, select “Options”, then choose the “Keyboard/Mouse” selection. Enable the “Allow Developers Console” option.

You can then use the ~ key to bring up the console and then type:

connect xx.xx.xx.xx

Where xx.xx.xx.xx is the LAN ip address of the server.

To allow internet users to connect you will need to open ports 27000 to 27050 in your router firewall. I also forwarded 27015 directly to the server LAN address just for good measure.

Friends connecting from the internet will then be able to connect to the WAN ip address of your server using the password that you provided them.

Note: if your router supports it you may be able to dispense with +ip and +hostip in your command line. If this is the case you will simply be able to connect to your server from a LAN PC by connecting to you WAN address.
