About this mod Author’s original text

An Expansion-like mod

Expedition – is a work-in-progress mod which aims to add a wide variety of content, crafted with the goal of not disrupting normal game's balance and lore, and built upon what themes and elements the world of Risk of Rain already had to offer.

Currently mod is in the early stage of development, which means some bugs here and there are expected and some things can be changed further down the line, but no serious errors or unfinished assets is left in any version of the mod. So feel free to play it right now!

For now, mod adds 15 items, 3 equipments, 2 interactables, 2 elites and 1 artifact for your gameloop, all complemented with authentic logs and achievements. More yet to come!

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:
