[b:7307ab63b2]Service Settings[/b:7307ab63b2] 

This is the place you go to if you want to change information about the service itself.  Things like the IP, Port, CPU priority etc...  You shouldn't have to ever go into here.

[b:7307ab63b2]Config Files [/b:7307ab63b2]

Go into here to edit the config files.  The config file you want to focus on is &quot;server.cfg&quot;.  In it are a bunch of settings:

rcon_password - The admin password

sv_password - Password you use to login to join the server.
 
mp_gamemode - The game mode.  Right now it's on &quot;survival&quot;.  It can be &quot;coop&quot; - 4 players killing shit or &quot;versus&quot; - 4 survivors vs 4 zombies.

z_difficulty - The difficulty of the game. Easy = Easy, Normal = Normal, Hard = Advanced, Impossible = Expert

[b:7307ab63b2]File Manager[/b:7307ab63b2]

This the entire directory structure of L4D.  Like &quot;Service Settings&quot; you should never have to go in here.

[b:7307ab63b2]Command Line Changer[/b:7307ab63b2]

Go into here to change the command line.  You want to edit the command line that says &quot;EDIT_THIS&quot;

Co-op:

l4d_airport01_greenhouse (Dead Air)
l4d_farm01_hilltop (Blood Harvest)

Survival:

l4d_sv_lighthouse
l4d_airport05_runway
l4d_farm05_cornfield
l4d_hospital05_rooftop
l4d_smalltown05_houseboat

You can use any level where you activate a horde.  I've listed the final maps for all the co-op levels and Lighthouse.  If you just pick any map you'll end up just walking through a zombie-less co-op.

The server logs.  Duh.

[b:7307ab63b2]Run Steam Update[/b:7307ab63b2]

Use this to update the server.  Be sure to stop the server before you do this.  This will contact Steam and update the server automatically.

[b:7307ab63b2]Game Mods[/b:7307ab63b2]

Don't use this.  This is broke.


You can also use HLSW ( http://www.hlsw.org/ ) or use the dev console to change the game as well.  You're on your own there.
