INSTALLATION from fully unmodded

This is if you don't already have BepInEx installed into the files

To add it to the game, simply put the

CONTENTS of the PartyUp folder into:

Program Files (x86)\Steam\steamapps\common\ATLYSS

(or rightclick ATLYSS on Steam > Manage > Browse Local Files)

These are the files if you're having issues of telling

which files are meant to be in the ATLYSS game folder:

BepInEx (folder).doorstop_version

doorstop_config.ini

winhttp.dll

INSTALLATION with BepInEx installed

To add it to the game, simply take

the PartyUp.dll file and put it into the plugins folder of the existing

BepInEx plugins folder in the ATLYSS files found at:

Program Files (x86)\Steam\steamapps\common\ATLYSS\BepInEx\plugins

(or rightclick ATLYSS on Steam > Manage > Browse Local Files > BepInEx > plugins)

NOTE: If no plugins folder is present, create one instead

as BepInEx doesn't come with it's own plugins folder

(As of BepInEx 5.4.23.2)

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.

Dependencies

Install these first, or the mod will not work:
