-Quest or Standalone: First you would need go inside userdata that is in here and inside of custom audio copy all audio files and go to melon loader and then to com.StressLevelZero.BONELAB and in the there go in UserData and in CustomAudio and paste audio files in there.

-Steam or PCVR: First you would need go inside userdata that is in here and inside of custom audio copy all audio files and now if you have bonelab on meta store then go to where you installed meta quest link app which can be Disk C or D or E but in my situation it is C:\Program Files\Oculus\Software\Software\stress-level-zero-inc-bonelab\UserData\CustomAudio and paste audio files in there,and if you have bonelab on steam then go to C:\Program Files (x86)\Steam\steamapps\common\BONELAB\Userdata\CustomAudio or go to steam, then right click on bonelab and then go to manage and, in there go to browse local files, and then go to AppData and, in there go to custom audio and, paste audio files in there.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide.
