About this mod Author’s original text

SteamJunction mod for Subterranauts

Overview

Allows Steam invites/joining work with Subterranauts multiplayer

What It Does

  • Creates Steam lobbies automatically when you host a game
  • Lets friends join through Steam invites instead of room codes
  • Works with CrewLateJoin mod if you have it installed

Caution

This mod is responsible for handling the launch arguments and logic to join a lobby, so even though your friends will be able to receive invites, or right-click your name and click Join, they will not be able to join the lobby without SteamJunction installed.

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:
