Released: August 15, 2025 | Compatible with Game Version 1.117.227

Transform your Sims 4 experience with the most comprehensive and powerful mod available. MC Command Center revolutionizes gameplay by adding advanced story progression, complete population control, and extensive customization options that breathe life into every sim household in your world.

MC Command Center (MCCC) is the most advanced and feature-rich mod for The Sims 4, developed by Deaderpool. This powerhouse mod transforms your static sim world into a dynamic, living environment where unplayed households continue their lives autonomously through realistic story progression.
