True Solo Mutator

Until this mutator, the only way to get KF2's full difficulty was through HoE co-op first with tweaked Controlled Difficulty layered on top. For those who could easily have this, great, but if not?

Atrocious internet?
No friends and don't like playing with randoms?
Not enough people?
Don't like people?
Want to practice in an identical environment where mistakes don't harm anyone else?
Face the Zed army as the lone wolf you always wanted to be without dead teammates?

Too bad ¯\_(ツ)_/¯

Controlled Difficulty can only make your solo games like co-op in every way but these crucial 3.

1. Zeds still having massively reduced damage outputs
2. The Syringe still magically healing 50 base HP
3. Hans, Pat, and Mat still having massively reduced speeds

Well, your search for a solution ends here.



This mutator has 3 features:

1. Removes the massive solo damage nerf from Zeds. Zeds' damage is now 1:1 with their co-op counterparts on the chosen difficulty. (See "Known Issues On Its Own" discussion tab)

2. Removes the massive solo Syringe buff. The Syringe now has a 20 HP base heal instead of 50 HP, just like co-op.

3. Removes the massive solo speed nerf to Hans, Patty, and Matty. All 3 are now 30% faster on spawning to mimic co-op Last Man Standing boss wave scenarios after 2 minutes. The King Fleshpound and Abomination are exempt like in co-op.

As a Medic/Berserker/Survivalist, you'll learn how to become a universal boss slayer even when using Controlled Difficulty to fake 6P HoE+ scaling.

As a squishy perk, especially on high scaling - Hans, Patty, and Matty generally become death sentences just like in co-op. They now train you in both damage maximization and evasion before you inevitably die.


This mutator is primarily designed to work in solo, preferably with CD. Although appearing to work properly in multiplayer, I need user feedback to fix issues there. Mix mods cautiously. Please report issues in the appropriate discussion tabs for visibility.


To start, go in-game, open the console with the tilde key and paste this:

open KF-testingmapredux?difficulty=3?gamelength=2?mutator=TrueSolo.TrueSoloMutator


Better yet, grab Controlled Difficulty: Blackout Edition and learn to use it in with my mutator for a real challenge! This mutator also patches the Matriarch's sprinting in CD.

Here's 2 CD command strings I personally have and recommend for beginners, along with my mutator. Paste these either in the console or in your server's activation BAT file with "start .\kf2server\Binaries\win64\kfserver" replacing "open" if it's the latter. No quotations.

Note: Add "?boss=matriarch/patriarch/hans/kingfleshpound/abomination" to choose your boss. No quotations and pick one boss.

"MM" (aka "Max Monsters") is the amount of Zeds permitted to be alive at once. Vanilla Hell on Earth goes: 1P = 12, 2P = 18, and 3P+ = 32

"Difficulty=" codes are: 0 - Normal / 1 - Hard / 2 - Suicidal / 3 - Hell on Earth

See Blackout's INI for other variables you can include in your command strings!


If you want this on your own server, look up the "Dedicated Server + Workshop" guide by Zerreth, then skip to and follow the "Workshop Integration" section.

To update this mutator on your server, just restart it. The updated files should download automatically. Be sure to check however. Multiple restarts may be needed.


To install and update a map on your server, the process is more manual but only the first time. You must login to your Web Admin [wiki.killingfloor2.com] and manually add and save the map to your server's maplist. Obtain your IP through CMD > "ipconfig" > "IPv4 Address".

If you want to but haven't yet created a server for yourself, there's an informative guide on the Killing Floor 2 wiki here[wiki.killingfloor2.com].


You sure can! First, get Notepad++. In Program Files (x86) > Steam > steamapps > workshop > content > 232090 > 2263399756 > Config is KFTrueSolo.ini.

Here you can edit the damage or speed scales for individual Zeds and alter the Syringe's base healing and recharge on a per difficulty basis. There are also several special toggleable variable sets available for these features along with a specially hand-crafted usage guide and comment code layout within the INI so you'll know what does what and is where. No troublesome reverse engineering a mile-long wall of meaningless variables necessary!


Changing values is easy!

If customizing for your client, go to the INI master copy in the filepath above, edit, save, and you're done!


For servers the INI's file path and process is different.

Go to PCServer-KFEngine.ini then put "//" behind "ServerSubscribedWorkshopItems=2263399756" under "[OnlineSubsystemSteamworks.KFWorkshopSteamworks]". This stops the server from checking and overwriting the master copy to "update" it after detecting altered values from the defaults. Only then can you go to yourserverfolder > kf2server > KFGame > Config, to edit and save. In order to install new actual updates however, you must manually check for updates here then undo the "//".

Create backups as updates from me overwrite the INIs! Editing must be done before you load the game. For any editing done afterwards to take effect, the client or server must be restarted.


For those looking to learn/create, here's the tidied up now cleaner source code on GitHub: https://github.com/Macrallex/TrueSolo

Note: add "?ts=4" at the end of file URLs to view code with proper indentation. No quotations.

Developed with Notepad++.


I no longer possess the knowledge or the will to update this further, but I'm glad others enjoy it. YOU HAVE FULL PERMISSION TO CREATE VARIATIONS OF THIS MOD OR UTILIZE ITS SOURCE CODE.
