| Fission-C |

|:---- |

| Sector C of Fission houses an old toy factory later repurposed as nuclear power plant.

However this power plant was abandoned many rotations ago due to health inspection failure.

Now this structure is crumbling and all those who visit will leave changed.

High value radioactive materials remain inside.

|

| There are 10 new themed scrap items to find on this moon.

Difficulty: A

Some people suggested I should make a Ko-fi so here it is.

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:
