FAQ:
Do achievements work?
- Yes!
Does only the host need this?
- Yes! Only the host needs to install this mod! Other players can optionall install the mod to see a working end screen!
Is the mod safe?
- Yes, you can view the code on github.
Is the mod still working after the most recent update?
- In all likelihood yes - try it before asking. Please report any issues to the github page.
Installation (Automatic - Recommended)
With Thunderstore you can use a variety of Mod Managers to automatically install mods and create profiles.

You have two options:
- Gale: https://github.com/Kesomannen/gale/releases
- R2ModMan: https://github.com/ebkr/r2modmanPlus/releases

Once you have these installed, you can use them to search the Thunderstore for mods, create a profile or use the default profile, search for PEAK Unlimited and press install. To play modded you then have to press play on the mod launcher - launching with Steam will load vanilla.
Installation (Manual - Not Recommended)
Download
https://thunderstore.io/c/peak/p/glarmer/PEAK_Unlimited/


Only the host needs to install this mod!

Manual Install
1.) Download Bepinex from here
https://thunderstore.io/c/peak/p/BepInEx/BepInExPack_PEAK/

2.) Extract the contents of that zip into your game directory (default: C:\Program Files (x86)\Steam\steamapps\common\PEAK) resulting in a folder that has the following files:



3.) Start the game and close it again, this does the first time set up for BepInEx.
This creates the bepinex/plugins folder, it is necessary

- If you are on linux add the startup command: WINEDLLOVERRIDES="winhttp=n,b" %command%

4.) Download the mod from here (Click Manual Download): https://thunderstore.io/c/peak/p/glarmer/PEAK_Unlimited/

5.) Open the downloaded zip file. Copy and paste the PeakUnlimited.dll file into your PEAK directory - (steam directory)\PEAK\BepInEx\plugins. All the other files can be ignored.

If you don't have a plugins folder, you either need to do step 3, or your bepinex installation is incorrect.

6.) Run the game

Configuration
- Configuration can be found at: (steam directory)\PEAK\BepInEx\config\PeakUnlimited.cfg
Important
- DO NOT UNDER ANY CIRCUMSTANCE COMPLAIN ABOUT BUGS TO THE DEVELOPERS WHILE USING MODS. UNINSTALL MODS IF YOU ENCOUNTER BUGS AND THEN REPORT THEM IF THEY ARE STILL PRESENT.

- Always check the steam discussions first if you experience a bug, it seems the game has a few common issues that are unrelated to the mod and you may find a solution there.

- Try swapping between DX12 and Vulkan if you are having issues. Personally I find DX12 to work best.
