# Hardcore-SK: a curated RimWorld mod overhaul maintained as a single download

> A RimWorld overhaul that bundles over a hundred technologies, an extended production chain and retextured content as one curated mod set, distributed through a Windows launcher or a manual extract into the game's Mods folder, with the live work now moved to a successor repository.

## This repository is a snapshot, and it says so

The first thing the project notes do is redirect you. It carries a heading saying the project is outdated and to use the HardcoreSK/Hardcore-SK repository instead, repeated in Russian as well. What follows is an archived description kept behind a collapsible details block.

That matters for how you read everything else in the repository. The content below describes the mod set as it was, and the distribution links point at a launcher hosted under the HardcoreSK organisation rather than at this repository's own releases.

The repository layout confirms the shape of the deliverable. There is a `Mods/` directory holding the individual mods that make up the overhaul, a `Config/` directory with the configuration files RimWorld needs, a `CharacterEditor/` directory, a `ModsConfig.xml` at the root that the game reads to know which mods are enabled, a `version_hsk.txt` file recording the version, a `Using_Whole_Repo_In_Game_Root.md` note about placing the whole repository in the game root, and a `update_gitattribute.py` script that appears to maintain the `.gitattributes` file used for line ending handling on a repository with a large number of files.

The primary language recorded for the project is C#, which is consistent with the launcher being a .NET application rather than the mods themselves being code. RimWorld mods are mostly XML definitions, and the repository carries an `XML modders` role in its credits, which is exactly the kind of contributor who writes those.

The project also runs a Discord server, and the README describes it as the place to ask questions, comment or contribute, with the launcher requiring a validated account for the linked invite.

## The problem it solves is mod pile-up, not missing content

The stated motivation is worth reading closely, because it is about curation rather than feature count. The project idea came from playing with mod packs and noticing that although many individual mods are good, game balance becomes messy and there are often bugs and incompatibilities when they are all played together. Hardcore SK is presented as a carefully curated list of mods that are optimized, balanced and maintained by the author and a team of modders, alongside original content the team creates continuously.

That framing explains what the mod set is actually for. It is a base for playing RimWorld as a colony simulation with real production constraints rather than as a collection of disconnected systems. The description mentions an improved and elaborate production chain, over 100 technologies to research, new events and challenges, new foods, wardrobe and arsenal content, enhanced AI features, quality of life options, and virtually everything retextured.

The design goal stated is to add a growing complexity to gameplay while immersing the player in the story, and the argument is that the more variety of challenges the colonists face, the more interesting the story becomes.

The scale of the set is visible in the credits. The team is organised into lead developers, coordinators, Discord moderators, artists, coders and XML modders, and the individual credits list runs to several dozen names, plus a Patreon credit. That is a substantial ongoing effort rather than a personal mod.

One point the project notes make that is easy to miss: other mods which are not included in the project are not recommended. The project is opinionated about the loadout, and it maintains lists of known compatible optional mods and patched optional mods on its Discord channels for the ones you might add yourself.

## Installing with the launcher on Windows

The launcher is the recommended path for Windows users and lives in its own repository, HSK-Launcher. The download link points at the latest release of that launcher, and the feature list covers updating HSK in a few clicks, a built-in proxy in case GitHub is unreachable, an optional ModsConfig update, launching the game through Steam or from a custom location, checking for new updates at startup, and installing a specific older version from an archive.

The requirements are modest and worth noting before you start. You need to launch RimWorld once first so the game generates its folders and configuration files, and you need the .Net 6 Desktop Runtime, which the documentation notes is installed by the Windows Update Center starting with Windows 10. The launcher will ask you where the RimWorld executable lives, and for Steam installs the path is usually `C:\Program Files (x86)\Steam\steamapps\common\RimWorld\RimWorldWin64.exe`.

The launcher is Windows only. On macOS and Linux you install manually.

## Manual installation means emptying your Mods and Config folders

The manual route is deliberately blunt, and you should read it before you start because it deletes things. The steps are: install either the development branch for RimWorld version 1.5 or the master branch for 1.4, then go to the folder you installed the game in and delete all mods inside your `Rimworld\Mods\` folder. Open the downloaded Hardcore SK zip and extract everything from the `Hardcore-SK-master\Mods\` or `Hardcore-SK-Development\Mods\` folder into that now empty Mods folder. Then go to the RimWorld config folder, delete the files in it, and copy the config files from the `Config` folder of the archive into it, along with the `Character Editor` folder. Finally copy `ModsConfig.xml` from the root of the archive into the `Config` folder.

The configuration folder differs per platform:

```bash
C:\Users\your user name\AppData\LocalLow\Ludeon Studios\RimWorld by Ludeon Studios
```

for Windows, with the documented shortcut of opening the Run dialog with the Windows key plus R and typing `%APPDATA%\..\LocalLow`. For Linux users the path is `/home/your user name/.config/unity3d/Ludeon Studios/RimWorld`, and for Mac users it is `/Users/your user name/Library/Application Support/RimWorld`.

Finally, open the game, check the mods list at the title screen, enable the optional mods you want or disable the ones you do not, switch the language if needed, and play.

Note that the branch names and version numbers in these instructions belong to the archived state of the repository. The master branch is described as the stable version, usually one version behind the latest RimWorld, and development as the work in progress for the latest game version but more likely to contain bugs.

## Language support and the Chinese translation split

The mod set ships with language support for English and Russian, and partial support for Spanish and Korean. Chinese is handled differently: it is delivered through separate mods rather than inside the main archive, one covering core content and one covering everything else, both linked from the project notes.

That split is a small but real operational detail for a mod set of this size. Translation of a retextured, over 100 technology overhaul is a large ongoing job, and splitting the Chinese work out means the main download stays smaller and the translation can be updated on its own schedule.

The interface language for the game itself is switched at the title screen during the first launch step.

For anyone trying to combine this with the wider ecosystem, the project notes point at three mods designed specifically to work alongside HSK rather than being derived from other packs: several overhaul mods from Vile's Mods, the Parabellum combat mod, and Minerals Extra. Each is a separate project with its own maintainer, which is the normal arrangement for a large community mod ecosystem: the core set is curated and shipped together, and the add-ons are independent projects that declare compatibility with it.

## Versioning follows the game, and the release history shows the gaps

Hardcore SK versions are tied to RimWorld releases, and the tag names in the repository make that explicit. The most recent tag is 10.3, described as HSK Rimworld for 1.4 Final Build (v1.4.3901), published on 2025-10-06. Before that came 10.2, HSK RimWorld for 1.3 Final Build: Ideology (v.1.3.3389) in October 2023, and 10.1, HSK RimWorld for 1.2 Final Build: Royalty (v.1.2.3062) in August 2021.

Those gaps are the interesting part. A major RimWorld expansion or release forces a large content update, and the tag cadence shows roughly a year between the 1.3 and 1.4 updates and two years before that. So the reasonable expectation for a new RimWorld version is a new major HSK version some months later, not a quick patch.

The repository is not archived and the last push was on 2026-10-10, so the archive still receives commits even though the description has moved elsewhere.

The licence for this repository is recorded as unknown, which is unusual and worth pausing on. The successor repository and the launcher are the maintained distribution paths, and the project credits artists, who retain rights in their own work even in a collaborative mod set. If you plan to reuse any of the retextured art or XML content outside this project, you need to establish the terms directly rather than assuming a permissive open source licence applies.

## Conclusion

Adopt Hardcore-SK if you play RimWorld and want a single balanced overhaul with extended production, over 100 technologies and retextured content instead of assembling dozens of mods yourself, and are prepared to replace your Mods folder. Do not start from this repository, because its README marks it as outdated and points to a successor repository for current work. Verify first which RimWorld version your copy targets, since releases and branches are tied to specific game builds, and note that the licence for this repository is unknown while the Discord launcher download and the successor repository are the maintained distribution paths.
