Bonelab mods are relatively easy to install, once you know how to do it. Stress Level Zero has also provided a comprehensive MarrowSDK Wiki, which explains the entire process of building a mod as well.

Have an opinion on this article? We'd love to hear it!

Marrow SDK

First off, you need access to the MarrowSDK. This is the software development kit that Stress Level Zero has made available to anyone who wants to make mods for Bonelab.


If you do want to make any mods of your own, make sure you are running Unity version 2021.3.5f1.

You're also going to need a working knowledge of how to actually use Unity, otherwise, things are going to get confusing quickly.

Assuming you meet these requirements, and your computer is up to the task of running Unity, you'll then need to make sure you complete the following steps:

  1. Ensure Git is installed before launching Unity.
  2. Download Unity 2021.3.5f1 The Unity Hub is recommended to help manage different versions of Unity and multiple projects.
  3. When installing Unity 2021.3.5f1, be sure to include the following modules: Under Platforms, select Android Build Support and its sub-items, Android SDK & NDK Tools and the OpenJDK. Lower down the list, and add Windows Build Support (IL2CPP).

That's as far as we're going to go with telling you how to actually create a mod, before we confuse ourselves. If you want to learn more, simply visit the Wiki we referenced earlier in the article.

Installing Built Mods

Now we come to the heart of the matter. The marrow in the Bonelab mods query, if you will. Stress Level Zero offer the following advice when it comes to installing mods, with the expectation that you will generally be installing mods you've built for yourself:

On PC, drop your entire mod folder into: C:\Users\USERNAME\AppData\LocalLow\StressLevelZero\Project4\Mods\

  • Then go to the Mod Node in the Central Hub
  • When this wakes up, click downloads, and click on the pop-up.
  • You'll see a list of options saying play, installed, approved, external and settings. Choose external.
  • This will provide you with all the mods you've previously added to the folder above.
  • Click the mods you want to install, and they will appear in your game.

On Quest 2, first of all, you need to ensure that your Quest is connected to your PC, and that in the headset you click Allow on accessing data. Next, drop your entire mod folder into: This PC\Quest 2\Internal shared storage\Android\data\com.StressLevelZero.Project4\files\Mods\

You can check out a few examples in our best Bonelab mods article. Installing mods from sites such as or NexusMods is thankfully a really easy process. We'd always recommend carefully reading the installation instructions for each mod, but in general, the process is as we've described above.

That's all you need to know about installing mods on Bonelab. When you're ready, you can find out if there is a Bonelab PSVR version, or the difference between Bonelab vs Boneworks.
