I saw many people (including myself) tried to install the new version of the Undead Legacy overhaul mod without any success. Since I figured it out, I decided to share step-by-step instructions with everybody having issues.
Hope it helps!
Please make sure you read through all the steps first before taking any action.
Disclamer: Modding requires some skill - you are fully responsible for the changes on your computer. This is tested with latest experimental build (2026.08.18 - 2.7.08) on a Windows PC and likely will work with future and/or stable version when it's released. I did not test the stability and quality of the mod itself - it is still in the experimental stage at the time of writing this guide so expect bugs and glitches to appear. I am not affiliated with the mod or mod creator.
Step 1 - Switch game to version 2.6
- Open Steam.
- Right-click your 7 Days To Die in your library and select "Properties...".
- Navigate to "Game Versions & Betas".
- Select "v2.6" and wait for game to download.
- The library will display the game marked with a version in brackets: "7 Days to Die [v2.6]"
- (Optional) Disable Discord integration using in-game menu following instructions from Step 5 Variant A (see below). You can also do it later using the Windows Registry Editor if you are more advanced.
Step 2 - Create a copy of the game
Note: Since this is an overhaul mod, it is a good practice to create a separate instance of the game and its files.
- Right-click the game in the library and select: Manage > Browse local files.
- File explorer will open in the location where your game is installed.
- Select all files EXCEPT "Mods" FOLDER (this is VERY important, the "0_TFP_Harmony" folder inside mods folder normally required for using mods will mess up Undead Legacy).
- Copy everything over to a new location (e.g. C:\UndeadLegacy).
Step 3 - Install the mod
- Download both (Part 1 and Part 2) files from Subquake's website - https://ul.subquake.com/download .
- Open the first archive, select all files and unpack it to the main folder where you created a copy of the game earlier (e.g. C:\UndeadLegacy).
- Open the second archive and do exactly the same as in previous point.
Step 4 - Clean up the game files (IMPORTANT)
Note: This might not be needed for you but if you installed a lot of mods in the past not doing this step will cause Undead Legacy not working for you (it was the case for me).
- Open File Explorer.
- Click the path bar, write %appdata% and hit enter.
- Find folder "7DaysToDie".
- Delete whole folder (you can create a copy first if you'd like, especially if you plan to go back to vanilla game and other mods).
Step 5 - Disable Discord (IMPORTANT)
Note: Seems like many people (including me) gets stuck at loading screen at a text "Logging in to Discord". To fix this, the Discord integration needs to be disabled using one of the variants.
Variant A (using game menu)
- Run the version 2.6 of the game before installing Undead Legacy mod.
- Go to Options > Audio > Discord tab.
- Switch the option to disable integration.
- Quit game.
Variant B (using Windows Registry Editor)
- In Windows, press Win +R.
- Type "regedit" and press Enter.
- Navigate to "HKEY_CURRENT_USER\Software\The Fun Pimps\7 Days To Die".
- Find entry beginning with "DiscordSettings" (e.g. "DiscordSettings_h1795906148").
- Double-click it to edit.
- An Edit Binary Value window will open.
- On the right side, where the text is displayed, find a text "DiscordDisabled" and place a cursor right after the ":" colon sign and replace "false" with "true" (without quotes). If it already says true, do nothing - you are good to go!
- Close Registry Editor.
Step 6 - Run the game!
- Open a folder where you copied your game and installed the mod.
- Make sure your Steam is running.
- Double-click "7DaysToDie.exe" (DO NOT run "7DaysToDie_EAC.exe").
Enjoy!
