I’ve been playing Killing Floor since I was kid and since the game is unfortunately pretty dead in terms of player counts nowadays, there aren’t many popular Killing Floor servers with higher player counts. Although the game is intended for 6 maximum players, custom servers may be configured to go much higher (up to 64 players in the first Killing Floor). I personally find gameplay on larger servers really chaotic and fun.
However, now that there really aren’t many popular servers, I’ve been playing with bots a lot of times using this mutator. While the bots are dumb at times and I also needed to install an unlimited ammo mutator since the bots run out of ammo very quickly, it is really fun!
I’ve also installed the Server Perks mutator which comes with a bunch of features and also allows perks to go over level 6.
If you try using the Bots mutator along with the Server Perks mutator, the bots won’t receive perks. This is because the Server Perks mutator creates custom perks that the Bots mutator doesn’t know to use by default. Fortunately, the developer of the Bots mutator made the list of perks to select from configurable.
To allow the Bots mutator to select perks from the Server Perks mutator, navigate to the System/KFBots.ini file inside of the Killing Floor directory. The Killing Floor directory is usually located in your Steam directory at steamapps/common/Killing Floor.
From here, remove any lines that start with BotPerks and replace them with the following.
BotPerks=ServerPerksP.SRVetSupportSpec
BotPerks=ServerPerksP.SRVetBerserker
BotPerks=ServerPerksP.SRVetCommando
BotPerks=ServerPerksP.SRVetFieldMedic
BotPerks=ServerPerksP.SRVetFirebug
BotPerks=ServerPerksP.SRVetSharpshooter
BotPerks=ServerPerksP.SRVetDemolitions
I hope this helps!
