MC Command Center Sims 4 v2026.3.1 (Updated 2026)

The MC Command Center Sims 4 is a script mod that gives you more control over NPC story progression. Once installed, it adds several options to your game’s interface. For example, the MC Career module includes settings that let you customize how careers and school systems work. You can download the latest version (2026.3.1) of MCCC below. It is fully compatible with the new patch 1.124.54.

What Is MCCC?

It is a popular mod developed by Deaderpool to give more customization and control over Sims, households, and the overall world. This toolkit allows you to use cheats, manage story progression, NPC behavior, population settings, kill, delete, or rename Sim, and more through the in-game menu with a single click.

What’s New in 2026.3.1 (May 12, 2026)

The latest version focuses heavily on compatibility with the Royalty & Legacy expansion and restoring community-favorite features. Here are the major changes:

• Fix for pregnancy caused by the Sims 4 update.
• Royalty & Legacy Support: A massive suite of new cheats has been added for the R&L expansion. You can now force NPC secret generation, trigger Power Shift Events, and manage Noble Career rivals or Dynasty details directly through the MCCC menu.
• Relationship Bits Return: By popular demand, the ability to add/remove Relationship Bits is back under the Relationships menu. Note that family/spouse bits are excluded due to base-game code changes.
• Death Settings Revamp: To keep the menu clean, a new Death Settings sub-category has been added under Gameplay Settings. You can now also toggle “Allow NS Random Deaths” to prevent Neighborhood Stories from killing off your favorite Sims.
• CAS & Dresser Improvements: You can now filter “Paste Tray Sims” by name, and MC Dresser now includes an option to remove Facepaint alongside makeup.
• Bug Fixes: Fixed the “Watch Sky with…” interaction glitch and resolved an issue where scenario headlines (like “Court Advisor”) wouldn’t disappear after an event.

Key Features

Base Module

It is required for all other modules to function and display properly. It allows access to settings and commands through in-game computers, mailboxes, or Sims, and enhances gameplay with story progression and cheat replacements.

Story Progression

It adds dynamic progression for unplayed Sims and enables autonomous marriages, pregnancies, career changes, and household moves, mimicking The Sims 3’s story progression.

Global Settings Control

It is used to adjust in-game mechanics like lifespan per age stage, relationship decay rates, and time speed and notification settings (e.g., aging/death notifications for played Sims only).

Cheat Simplification

It replaces the cheat codes system with a modern one-click activation system. For Example, if you want to use the money cheat, just click on add money and enter the amount (999999 max.), and the amount will be credited into your account.

Key Modules and Their Features

Here is the list of all modules and their features that I use in the game.

MC CAS (Create-a-Sim)

This module lets you customize your Sims’ appearance, like hair, makeup, or accessories, without having to enter Create-a-Sim. It also gives you control over the body shapes and sizes of townies, so you can prevent random weight or muscle changes over time. You can fine-tune genetics by setting what children inherit from their parents, and even blocklist certain traits for Sims or pets to avoid unwanted assignments.

MC Cheats

With MC Cheats, you can instantly modify things like motives, emotions, skills, and careers. It also allows you to add satisfaction or business points, reset broken Sims, and adjust household funds with a few clicks. You can auto-enable handy cheats like Full Edit CAS or build/buy cheats, and even trigger random events or change lot traits without using cheat codes.

MC Cleaner

This tool keeps your game tidy by fixing common annoyances—like syncing last names for married Sims, removing stray accessories from outfits (like glasses in the shower), or properly deleting culled Sims. It helps reduce clutter and can make your game run more smoothly overall.

MC Career

The career module lets you promote or demote Sims instantly, switch career branches, or tweak employment rates by age group. For example, you can help more teens or elders get jobs. It also gives you control over homework speed, vacation days, and job difficulty settings for both played and unplayed Sims.

MC Clubs (requires the Get Together expansion)

This module expands the club system by increasing the number of allowed members and offering better management tools. You can monitor club activities and control memberships more effectively than the base game allows.

MC Occult

If you play with vampires, aliens, or spellcasters, MC Occult gives you detailed control over how these Sims behave. You can adjust skill progression, enable or disable specific interactions, and even allow features like risky vampirism to spread the condition more organically. It also lets you force Sims to reveal their true form on command.

MC Population

This module helps you control how many Sims exist in each life stage (child, teen, adult, etc.) across your game. You can stop the game from filling your carefully designed houses with random NPCs and fix awkward townie outfits, especially if you use a lot of custom content.

MC Pregnancy

Here, you can manage every aspect of pregnancy in the game—from forcing pregnancies and setting baby gender, to enabling teen parenting. You can also control breakups by deciding who moves out, how custody is handled, and even applying child support. There are also inheritance rules you can tweak for extra realism.

MC Dresser

This module lets you fine-tune outfits globally or on a Sim-by-Sim basis. You can stop Sims from randomly changing into ridiculous clothes and maintain a consistent look across your world, including NPCs.

MC Tuner

Tired of your Sims constantly drinking water or kicking dollhouses? MC Tuner allows you to disable annoying behaviors like these. It also helps you control phone notification spam or turn it off entirely if you’re aiming for an off-the-grid experience.

MC Woohoo (optional, separate download required)

MC Woohoo adds depth to romance and pregnancy gameplay. It includes options for risky Woohoo, relationship dynamics, and more advanced control over how Sims connect romantically.

MC GEDCOM

For players who love managing family trees, this module helps you view, export, or manipulate genealogical data more easily within the game.

Fixed: script mod not working

If it is not working on your device, here is how to fix it.

• Download the latest version after the new patch. The latest supported version is 1.124.54.
• Make sure that your files are not placed in sub-folders.
• Clear the game cache by deleting the localthumbcache.package file.
• If the issue still exists, tell me through the comment section in detail.

Final Thoughts

This isn’t just a tool; it brings new life to the game. When you’re feeling bored, enable it and explore features like teleporting or turning them into ghosts. You can also increase money, change clothes, or make a Sim pregnant. Take full control of their lives like a dollhouse with the MC Command Center. If you want to try out the beta version, you can join the Deaderpool on Patreon.

If you love to use mods like me, you should also try the UI Cheats and Slice of Life, as they are most popular among the players.
