ATF MutationStation adds new options for creating Mutator Runs in After the Fall VR, allowing you to play any mutator on any level at any time, instead of being restricted to only the 'current' mutator.
Both PCVR versions are supported (Steam and Oculus Rift). The plugin does not support Meta Quest, Pico, and PSVR -- however, players on those platforms can join runs created with ATFMutationStation.
Important
This plugin is currently in Beta status. If you run into any issues, please open an Issue or DM me on Discord so issues can be fixed.

Warning
Use at your own risk!!
Generally speaking, After the Fall has not been hostile towards players using BepInEx plugins such as this, so it's commonly accepted to be safe practice as of this plugin's release. In other words, you are unlikely to be banned for using this - but there are no guarantees.
While I've made every effort to test this plugin and ensure it's free from bugs and issues, I provide no warranty or guarantees against any issues you may encounter. Use at your own risk.
- Compatible with After the Fall version 1.9.41947 (aka "Nightfall Update").
- Tested and working on PCVR (both Steam and Oculus Rift versions).
- Not compatible with Meta Quest, Pico, or PSVR versions.
Tip
While ATFMutationStation only supports PCVR version, players on all platforms are able to join runs created with ATFMutationStation!
As long as a PCVR player running ATFMutationStation creates the party, any other players can join in the fun!
As far as I'm aware, ATFMutationStation has no conflicts with any other plugins, and can be used alongside other plugins without issue. If you discover any conflicts, please open an Issue with relevant details.
Download and Install
Use the Full Version .zip below if you are installing After the Fall plugins for the first time. The full version .zip already includes BepInEx (version 6.0.0-pre.2) already within the .zip and is pre-configured, ready to go.
-
Grab the latest
ATFMutationStation-vX.X.X-full.zipfrom the Releases section. -
Extract the .zip file to your After the Fall game folder:
-
Steam default location:
C:\Program Files (x86)\Steam\steamapps\common\After The Fall -
Rift default location:
C:\Program Files\Oculus\Software\Software\vertigo-games-snowbreed
-
After extracting, launch the game. You now have new mutator controls in the 'Mutator Run' screen on the enlisting machines in the lobby.
Note
On first launch, startup will take a bit longer than normal as BepInEx does some initial setup. Subsequent launches will not have this delay.
Plugin-Only Version
If you already have BepInEx installed, you can find the .dll only on the releases page. Download the appropriate .zip and extract it to BepInEx\plugins in your After the Fall game folder.
If you are upgrading from an earlier beta of ATF MutationStation - and don't use any other plugins - fully removing the old version is recommended. The previous version used BepInEx 6.0.0-pre.1 and the current version uses BepInEx 6.0.0-pre.2 for improved runtime support.
Warning
If you are using other After the Fall plug-ins that still use BepInEx 6.0.0-pre.1, they will not work with 6.0.0-pre.2. In that case, you should stick with version 6.0.0-pre.1. You can find a .dll of ATF MutationStation compiled for BepInEx 6.0.0-pre.1 on the releases page.
Follow these steps to upgrade to a newer version of ATF MutationStation:
-
Fully uninstall the old version by removing these folders and files from your After the Fall folder:
\BepInEx\(and all files within)\mono\(and all files within).doorstop_versionchangelog.txtdoorstop_configwinhttp.dll
-
Grab the latest
ATFMutationStation-vX.X.X-full.zipfrom the Releases section. -
Extract the .zip file to your After the Fall game folder. This will install the latest version.
That's it! You're now upgraded to the latest version of ATF MutationStation. Note that the same delayed startup applies on first launch as BepInEx does initial setup.
Tip
As of release v0.5.0, all mutator controls are in-game and the .cfg file is only used for persistence. The GUI app 'ATF MutationStation Manager' previously used with v0.3.0 is no longer required and can be removed.
To disable or remove ATF MutationStation, you can use any of these methods:
- Remove Plugin Only: Delete
ATFMutationStation.dllfromBepInEx/plugins. This will remove ATFMutationStation and leave other plugins intact. Instead of deleting the .dll, you can also create a new folder,BepInEx/plugins-disabledand move any plugins you wish to disable into that folder, then move back later to re-enable them.
or
- Disable BepInEx Entirely: Rename
winhttp.dllin the After the Fall folder to something different, likewinhttp-disabled.dll. This will disable BepInEx entirely including all plugins. Rename back towinhttp.dllto re-enable.
or
- Complete Removal: To uninstall everything, remove these folders and files from your After the Fall folder. After removing these, you are back to stock ATF with nothing installed.
\BepInEx\(and all files within)\dotnet\and/or\mono\(and all files within).doorstop_versionchangelog.txtdoorstop_configwinhttp.dll
Once ATFMutationStation is installed, there will be new controls on the Mutator Run menu on the lobby enlisting machines:
With these added controls, you can now:
-
Select a Mutator Package by using the 'Next/Prev' arrows in the top right corner. Mutator details will update as you page through the 5 available packages.
-
Select a Mutator Level by using the 'Select Level' button and choosing a level.
Simply pick your preferred mutator and level, start the run, and have fun! :)
By default, ATF has five "Mutator Packages". Each package has 3 individual "mutator effects":
- Time Trial: 15 Minutes to Complete the Run
- Dry Season: Health Can No Longer Be Restored
- Sleight Of Hand: Advanced Reload Only
- Sleight Of Hand: Advanced Reload Only
- Ammo Shortage: Max Ammo is Halved
- Berserk: Snowbreed Deal Double Damage
- Ice Plating: Snowbreed Have 100% Armor
- Low Profile: Snowbreed Crawl Instead of Walk
- Case Hardened: Snowbreed Take No Explosive Damage
- Ice Plating: Snowbreed Have 100% Armor
- Infestation: 50% Increase in Snowbreed Spawn Rate
- Tough Skin: Snowbreed Health is Doubled
- Motor Function: Snowbreed can only be killed with Headshots
- Evolution: Snowbreed do not Mutilate or Stagger
- Cold Feet: Movement Speed is Halved
If something goes wrong, check the logs for signs of troubles:
-
BepInEx log:
BepInEx\LogOutput.log(within game folder) -
ATF's Player.log:
%LocalAppData%\Vertigo Games\AfterTheFall\Player.log
For live BepInEx logging, you can also edit BepInEx\config\BepInEx.cfg find [Logging.Console] and set Enabled=true which enables the BepInEx console.
If you run into any issues, please open an Issue with detailed feedback on what the issue is and how it can be replicated.
