[h1]Description:[/h1] This mod replaces current perk system in KF2 with a serverside perk progression with RPG elements, which let you buy individual stats and traits. [h1]Usage (Single player):[/h1] 1. Subscribe to this mutator; 2. Start KF2; 3. Open console (`) and input: [code]open KF-BioticsLab?Mutator=ServerExtMut.ServerExtMut[/code] (You can add some options or replace KF-BioticsLab with the map you want) [h1]Usage (Server):[/h1] 1. Open your PCServer-KFEngine.ini / LinuxServer-KFEngine.ini; 2. Add the following string to the [b][OnlineSubsystemSteamworks.KFWorkshopSteamworks][/b] section: [code]ServerSubscribedWorkshopItems=2085786712[/code] 3.

[h1]Mutator Setup[/h1] [url=https://steamcommunity.com/workshop/filedetails/discussion/2085786712/4241773359646835902/]Look here[/url] [h1]Is it possible to make the game harder?[/h1] Hmm... You can try to adjust skills and abilities, so that would be more difficult. Look here: WebAdmin → Settings → ExtServer Mod But it will be more efficient to use RPG Mod together with other mutators (which add new zeds or game modes). You can use [url=https://steamcommunity.com/workshop/filedetails/discussion/2085786712/4241773359647296750/]my experience[/url] or come up with something of your own. [h1]If not working[/h1] Older versions of Server-Ext have the same file names - this can cause conflicts if you subscribe to them. Therefore: 1. Check your subscriptions. If you are subscribed to old versions of the mutator, cancel them. 2. Clear the cache (the game doesn't clear it). It's here: [code] Client: C:\Users\\Documents\My Games\KillingFloor2\KFGame\Cache\ Server: /Binaries/Win64/steamapps/workshop/content/232090/ /KFGame/Cache/ [/code] If it’s not a problem for you to download all subscriptions again, you can simply clear this folder(s). Your subscriptions are downloaded the next time you start the game/server. If you do not want to download the subscriptions again, delete only those folders that contain the files: [code] ServerExt.u ServerExtMut.u [/code] 3. Reinstall RPG and try again.
