RimWorld 1.4.3901: The Complete Guide to All DLCs and What’s New
In the sprawling universe of colony simulation games, few titles command the reverence and addictive loyalty of Ludeon Studios’ RimWorld. For the uninitiated, it’s a story generator about crash-landed survivors trying to build a home on a hostile frontier. For the veterans, it’s a complex tapestry of human psychology, logistics, and tragedy.
Recently, a specific version number has been circulating in forums, modding communities, and digital storefronts: RimWorld 1.4.3901. If you are searching for this exact build—often labeled as “RimWorld 143901 all DLCs new” —you are likely looking for the definitive, most stable, feature-complete version of the game available today.
This article breaks down exactly what version 1.4.3901 includes, how it integrates all three major expansions (Royalty, Ideology, and Biotech), and what “new” elements seasoned players need to know before launching their next colony.
What is Build 1.4.3901 (143901)?
First, let's clarify the numbers. Following the massive Biotech expansion launch, Ludeon released a series of patches (1.4.3900, 3901, etc.) to squash bugs, rebalance mechanoids, and optimize performance. Build 143901 (the Steam manifest ID) is widely considered the most stable "vanilla-plus" version.
Key fixes in this patch include:
- Optimized Children & Pregnancy: Fixed issues where children would inherit incorrect xenogenes. Pregnancy cravings no longer soft-lock your game if a pawn is incapable of walking.
- Mechanoid Raid Balancing: Reduced the frequency of "Diabolus" triumvirate raids in the first year.
- UI Overhauls: The gene assembly interface has been cleaned up, making it easier to splice modded genes with vanilla ones.
- Performance: Significant reduction in TPS (Ticks Per Second) drains from large wastepack infestations.
