Improved Bots (Advanced)

This mod has been updated for the Last Stand update!

After subscribing to this addon, navigate to the location that the game is installed (or right-click the game in your Steam library > properties > local files tab > browse local files). From here, open the left4dead2 folder, then the cfg folder. Now open the listenserver.cfg file (with any text editor, such as Notepad) and copy/paste everything from this post into that file. Save and exit.

Also in that cfg folder is an addonconfig.cfg file. You'll need to open this file and change the values next to "versus", "scavenge", and "mutation15" to 0 for mods to work in those modes.

When you get in-game go to Options > Keyboard/Mouse > Edit Keys/Buttons, then scroll all the way to the bottom of that menu to find various mod features which you can bind to any key.

The listenserver.cfg file may need to be updated if this mod is updated. If something doesn't seem to be working try clearing that file then copy/paste everything from that post again.

• Allows you to play versus, survivial, scavenge and realism modes in single player with bots.
• Bots can use melee weapons. (Can be toggled)
• Bots will continue to play after you have died instead of ending the game.
• Bots will react much faster to a player being attacked by a special zombie.
• Bots can perform some simple actions, such as closing safe room doors.
• Bots will move around a player instead of shooting through them.
• Bots are much more likely to save their first aid kits for a player.
• Bots will try to stay in a tighter group with the player.
• Control the bots with a few commands. (Bind key for this in options menu)
• Easily change the map and game mode while in-game. (Bind key for this in options menu)
• Easily take control of another bot anytime during a game. (Bind key for this in options menu)
• Easily change the difficulty of the game at any time. (Bind key for this in options menu)
• Teleport bots back to you if they get lost or stuck. (Bind key for this in options menu)

• While this addon does improve the bots, it doesn't make them perfect. There is no way for me to fix every issue with the bots, but I have improved them in the areas that are possible. I realize they still aren't ideal teammates.
• Using bot commands will block Steam achievements for the rest of the campaign.
• The bot commands won't work on unofficial maps unless map is started through dev console.
• This version of the addon is ideal for single player.

SourceMod Plugins (Optional)
Unfortunately, the modding system for this game is very limited. However, installing SourceMod[sourcemod.net] will allow you to do significantly more with the game than a workshop addon ever could, through additional plugins. SourceMod is intended to be used for servers but can also be used for single player games! Here are some related plugins you may find useful:

No, not unless you unpack all of the mods and manually merge the changes for the conflicting files.

Is there a way for this addon to stop conflicting with VOX Vocalizer, Admin Menu & System?

@Erratic Noman:
There is really no reason for why this mod should impact loading times at all. If you have unsubscribed from the mod and it is still happening then that would imply the issue is being caused by something other than this mod.

My guess would be that both mods use the game/server settings file.

this mod messed up addon loads. If you install it it may DRASTICALLY increase your loading time. what used to load in 30 seconds takes 10 minutes to load even after unsubscribing

why does this mod conflict with the "Vanishing ragdolls" addon? and does it break anything?

@Eaarame for this to work with custom campaigns you need to load the map via console.

does not work with custom campaigns, can't switch between bots unless its a vanilla campaign
