How to Install Mods Downloaded from SacrificialMods.com

SacrificialMods.com hosts downloads for The Sims 4 mods such as Extreme Violence and Life Tragedies, and the site itself points you to a "How To Install" page for guidance. The general install process is the same as for most Sims 4 mods: download the file, extract it if it's compressed, place the .package files in your Mods folder, and enable mods in the game. The exact steps below apply to any mod you get from the site.

Before You Start

• Make sure The Sims 4 is installed and has been launched at least once, so the game has created your user folder.
• You need a way to extract compressed files (.zip, .rar, or .7z) — Windows and macOS both have built-in tools for .zip, but .rar and .7z usually need a free extractor.
• Close the game before adding files. Installing while it's running can cause the mod not to load.

Step 1: Download the Mod

1. Go to SacrificialMods.com and open the Downloads section.
2. Pick the mod you want (for example, Extreme Violence or Life Tragedies).
3. Download the file to a location you can find easily, like your Desktop or Downloads folder.

If a mod has multiple files or optional add-ons, download all the parts you want before moving on.

Step 2: Extract the Files

1. Right-click the downloaded archive and choose Extract All (Windows) or double-click it (macOS).
2. Extract to a folder you can open, not directly into the Mods folder — this avoids nested folders and stray files.

After extracting, you should see one or more files ending in .package. These are the actual mod files. Some mods also include a .ts4script file, which must stay alongside the .package files.

Step 3: Find Your Mods Folder

The Mods folder lives inside your Sims 4 user folder:

If you use OneDrive or iCloud to sync your Documents folder, the path may be inside that synced location instead. If you can't find the folder, launch the game once and check again — it's created automatically.

Step 4: Move the Files Into Mods

1. Open your Mods folder.
2. Copy the extracted .package (and .ts4script) files into it.
3. You can put them directly in the Mods folder or in a subfolder — subfolders help you keep track of which mod is which. Just don't go more than one or two folders deep, because the game only reads a limited number of levels.

Don't rename .package or .ts4script files, and don't change their extensions. The game matches files by extension.

Step 5: Enable Mods in the Game

1. Launch The Sims 4.
2. Open Game Options → Other.
3. Check Enable Custom Content and Mods.
4. Check Script Mods Allowed if the mod includes a .ts4script file.
5. Apply the changes and restart the game. Mods don't load until after a restart.

After restarting, you can confirm the mod is active by looking for its content in-game (for example, new interactions or menu options the mod adds).

Common Problems

• Mod doesn't appear: Check that mods and script mods are both enabled, then fully restart the game. Also confirm the files are actually inside the Mods folder and not still in your Downloads folder.
• Game won't start or crashes: A mod may be outdated or conflicting with another one. Remove the most recently added files and test again.
• Script mod errors: .ts4script files must not be inside a subfolder deeper than one level, and they must be enabled separately from regular mods.
• "Last Exception" errors: The site's navigation includes an "Understanding LE's" page, which explains these error logs. Check it if the game generates one after installing.

Keeping Mods Working

The Sims 4 patches regularly, and patches can break mods. When something stops working after an update, check the mod's release notes on SacrificialMods.com — the site states it provides detailed release notes for each mod, which is where compatibility fixes and version requirements are listed. Re-download and replace the old files when a new version is posted.
