About this mod Author’s original text

POPULATION: Abandoned

CONDITIONS: Scorching heat, due to lava rivers covering the surface

FAUNA: Mostly underground specimen, interior species

Acheron is a volcanic moon covered in obsidian rock formation and flowing magma rivers.

Contrary to its deep obsidian layer, research has documented evidence of intense tectonic and volcanic activity long before the moon's discovery. The exact cause of these events remains unknown.

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.

Dependencies

Install these first, or the mod will not work:
