📋 About This Mod

Adds a genuinely new buildable room that produces caps. Unlocks alongside the Nuka-Cola Bottler, costs the same to build and upgrade, staffs on Luck, upgrades through three levels and merges up to three wide. IMPORTANT: a vault containing

CAPS FOUNDRY

Description

Fallout Shelter gives you rooms for food, water, power, stimpaks and RadAway — but nothing that makes caps. The Caps Foundry does.

It is a real room, not a cheat menu. You build it from the build menu once your vault is large enough, staff it with dwellers, wait for a batch, and collect. It upgrades through three levels, merges up to three segments wide, costs caps to build and upgrade, and runs on Luck.

The room is built by adopting one of the room types Fallout Shelter ships in its code but never uses, and giving it the nuclear reactor's art tinted a different colour. Everything else — the production cycle, the build menu entry, the unlock condition, the pricing — is wired into the game's own systems rather than faked.

Before you install, read the uninstall warning under Requirements. A vault containing this room cannot be loaded without the mod.

Installation instructions

1. Install BepInEx (skip if you already have it)

  • []Download

    BepInEx_win_x64_5. 4.x.x.zipfrom the BepInEx releases page — you need the x64, Unity Mono build.[/]

    []Extract it into your Fallout Shelter game folder, the one containing

    FalloutShelter.exe. You should end up with

    winhttp.dll,

    doorstop_config.iniand a

    BepInExfolder next to the exe.[/]

    []Launch the game once, then close it. This makes BepInEx create its folders.[/]

To find the game folder: Steam → right-click Fallout Shelter → Manage → Browse local files.

2. Install the mod

  • []Extract this archive into the same game folder, so the DLL lands in

    BepInEx\plugins\CapsFoundry.dll.[/]

    []Launch the game.[/]

3. Check it loaded

BepInEx\LogOutput.logand look for a line beginning:

Registered 'Caps Foundry' as ProteinBarMain features

  • []A new buildable room that produces caps, listed at the end of the build menu.[/]

    []Unlocks with the Nuka-Cola Bottler and costs the same to build and upgrade, so it fits the vanilla progression instead of sidestepping it.[/]

    []200 caps per cycle per segment. Four hours at level 1, three at level 2, two at level 3. A fully upgraded three-wide Foundry makes 600 caps every two hours.[/]

    []Luck drives worker efficiency — the stat that already governs caps in this game.[/]

    []Upgrades and merges like any other production room.[/]

    []Automatic save backups on every game launch, ten sets kept, in

    %LocalAppData%\FalloutShelter\ModBackups\.[/]

    []Fully configurable: production rate, cycle times, room name, build price, unlock condition, the room's art, and its colour. See

    BepInEx\config\ovolo.falloutshelter.capsfoundry.cfg.[/]

Requirements

  • []Fallout Shelter for PC (Steam / Bethesda / Windows Store) — the Unity Mono build[/]

    []BepInEx 5.x, x64 Unity Mono variant[/]

    []Tested against Fallout Shelter 2. 5. 1 on Steam[/]

⚠️ Uninstalling — please read

A vault containing a Caps Foundry cannot be loaded without this mod. The room is saved under a room type the base game has no assets for, so removing the DLL makes that vault fail to load.

To uninstall safely:

  • []Sell every Caps Foundry in every vault.[/]

    []Save and quit.[/]

    []Delete

    BepInEx\plugins\CapsFoundry.dll.[/]

If you removed the mod and a vault will not open, either reinstall the mod, or restore a save from

%LocalAppData%\FalloutShelter\ModBackups\. The mod writes a backup of every vault each time the game starts, precisely for this.

Known limitations

  • []The room borrows the nuclear reactor's model, so it keeps that room's particle effects. New 3D art cannot be added to this game.[/]

    []The room's colour is configurable, but the underlying shape is whichever donor room you pick.[/]

Shout outs

Thanks to the BepInEx and HarmonyX teams — none of this is possible without them.

Fallout Shelter has no mod support and effectively no documentation, so most of this was worked out by disassembling

Assembly-CSharp.dlland reading crash reports. The mod's README includes a detailed technical write-up of everything that had to be satisfied to make a new room work: the room registry, the build menu's separate room list, per-room-type Unity scenes, object pools, room identity, unlock objectives, and the several places the game assumes a room never produces caps.
