RimWorld has officially updated to version 1.5 (Build 143901), and it is a massive leap forward for the colony simulator. Whether you are running a vanilla setup or a complete collection with all DLCs—Royalty, Ideology, Biotech, and the new Anomaly expansion—this specific build introduces foundational changes that make the game smoother, darker, and more complex than ever before. The Anomaly Expansion: A New Layer of Horror
The most significant addition to the "all DLCs" experience in version 1.5 is the Anomaly expansion. This isn't just another layer of management; it’s a shift into cosmic horror.
Monstrous Threats: Your colonists will now face invisible hunters, flesh-growing cysts, and mind-bending cults. Ensure your game is set to the correct
Containment Mechanics: You can now build high-security containment cells to study captured entities, unlocking a new dark research tree.
The Void: A new endgame path allows you to interact with a terrifying machine intelligence that threatens to consume the world. Biotech and Ideology: Enhanced Synergy
In Build 143901, the interactions between Biotech and Ideology have been refined. If you have all DLCs active, you can now create even more specific societies:
Sanguophage Cults: Refined blood-feeding mechanics and social roles for vampires.
Mechanitor Optimization: Better control over your personal robot army with improved pathfinding and UI updates.
Genetic Integration: New genes and xenotypes interact more fluidly with the Ideoligion system, allowing for "species-pure" or "hybrid-friendly" religions. Performance and Quality of Life Improvements
Even if you ignore the new content, Build 143901 brings technical upgrades that players have requested for years:
Performance Optimization: Significant improvements to the rendering engine, especially for large colonies with hundreds of animals or mechs.
Search Bar Functionality: A long-awaited feature allowing you to search for items in storage and specific buildings in the architect menu.
Wall Lamps: A former fan-favorite mod is now official! You no longer need to waste floor space on standing lamps.
Crawling: Downed colonists and enemies can now crawl to safety (or toward a medkit), adding a cinematic layer to combat. The Ultimate Modding Foundation
RimWorld 143901 is the current "gold standard" for modding. Most major mods—including the Vanilla Expanded series and Combat Extended—have updated to support this version. Running all DLCs provides the widest possible library of mod compatibility, as many high-end mods require assets from Biotech or Anomaly to function.
⭐ Pro Tip: When starting a new save on 1.5, use the new "Ambient Horror" setting if you want the Anomaly content to feel more like a background threat rather than the central focus of your story.

Post:
Just punched in 143901 with ALL DLCs active (Biotech, Royalty, Ideology, Anomaly).
Haven't even landed yet, but the world map is looking spicy.
Anyone else tried this seed yet? Found any hidden ancient dangers or perfect chokepoints?
Let’s compare spawns. Drop your starting tile below! 👇
The early days were defined by conflict, not with raiders, but with each other. Valerius demanded a throne room (Royalty) and fine meals. Mother demanded a slaughterhouse to honor her pig-god (Ideology). Unit-7 just wanted to build a grower mechanoid.
The tension broke during the first winter. A pack of man-hunting Wargs descended on the colony. Valerius used his psychic skip to teleport one away, but his pacifist nature prevented him from firing a gun. Twitch, going through withdrawal, accidentally fired an incendiary launcher into the colony’s fuel store.
The explosion killed the Wargs, but it also destroyed Unit-7’s workbench. In the ash, the colonists found a strange, glowing monolith (Anomaly DLC). Desperate for warmth, they activated it.
This DLC changed the game from a survival sim into a belief simulator. You now shape your colony’s religion, or "ideoligion."
The story of Colony 143901 began not with a crash, but with a cryopod malfunction. Sir Valerius, a Nobel fighter from the Empire (Royalty DLC), awoke alone in the wilderness. Used to satin sheets and psycasting, he instead found himself shivering in the rain, his elaborate cape offering little protection against the bitter cold.
He was soon joined by three unlikely allies: Twitch, a junkie transhumanist with a rusty shotgun; Mother, a pious pig-priestess; and Unit-7, a mute mechanitor (Biotech DLC) who was more interested in steel than salvation.
They named their settlement "New Bethlehem."
In the ever-evolving universe of narrative-driven colony simulators, few games command the same respect and obsessive devotion as Ludeon Studios’ RimWorld. As of the most recent stable build, version 1.4.3901 (often referred to in community hubs via its build ID, 143901), the game has reached a zenith of mechanical complexity and storytelling potential. For players searching for "RimWorld 143901 all DLCs new," you have arrived at the perfect moment.
This build represents the culmination of post-Biotech patches, integrating three major expansions—Royalty, Ideology, and Biotech—into a singular, polished experience. Whether you are a returning space cowboy or a new settler crash-landing for the first time, here is everything you need to know about playing RimWorld 1.4.3901 with all DLCs activated.
