To install a Valheim modpack on a FREAKHOSTING server, search for it on the Mods page, click Install (the pack’s mods come as its dependencies) and restart. The other way is the ModPack Startup variable: enter the pack’s Thunderstore dependency string and reinstall the server, because changing it requires a reinstall. Every player then installs the same pack and version.

​
Method 1: install a modpack from the Mods page

1

Back up first

Make a backup. A modpack adds many mods at once.
2

Find the pack

Open Mods under VALHEIM and search for the pack’s name in Search Valheim mods. If it isn’t listed, use Method 2.
3

Install

Click Install. The dialog lists every mod in the pack as a dependency. Click Install.
4

Restart

Click Done and restart the server.

​
Method 2: the ModPack Startup variable

The panel describes ModPack as: “Enter the Dependency String name for a ModPack to automatically be installed. NOTE: If the modpack Updates, you will need to update this variable with the new Dependency String… CHANGING THIS REQUIRES A SERVER REINSTALL”.
1

Copy the dependency string

On the pack’s Thunderstore page, copy its dependency string. It has the form Author-PackName-1.2.3.
2

Set the variable

Open Startup and paste the string into ModPack. See startup variables.
3

Back up and reinstall

Make a backup, then reinstall the server.
4

Start and check

Start the server and check the console for loaded mods.

Valheim Startup variables, including ModPack

When the pack updates, the variable doesn’t follow. Enter the new dependency string and reinstall again.

​
How players install the same modpack

Players need the same pack and version on their PC:
  1. Install a Thunderstore mod manager such as r2modman.
  2. Search for the same modpack and install the same version into a profile.
  3. Start Valheim from the mod manager and join the server.
If you built your own mod list instead, r2modman can export a profile as a code or file that friends import. Console players can’t use mods, so a modpack that players need doesn’t work for them on a crossplay server.

Frequently asked questions

What is a Thunderstore dependency string?

The pack’s ID and version, like Author-PackName-1.2.3. It is shown on the pack’s Thunderstore page.

​
Will reinstalling delete my world?

Make a backup first, always. Check server settings and reinstall for what a reinstall keeps.

​
How do I remove a modpack?

Switch off or delete its mods on Mods and restart. If you used the variable, clear ModPack as well.
