RimWorld has now sold over a million copies. Platinum status! This is a remarkably unexpected moment for me. The original Kickstarter only sought 1,000 sales, and that seemed like a lot. This is… crazy. Many thanks to all the players for buying the game, to Piotr Walczak, Ben Rog-Wilhelm and all others who worked on […]

RimWorld Beta 18 – A World of Story is released! Here’s the video (where I accidentally call it Alpha 18 – old habits die hard). To get the update: If you’re on Steam, the game will update automatically. If you’re DRM-free, you can re-download from the same link you got the game from originally. It […]

We’ll be closing sales for to the Backstory-in-Game package and Pirate King packages on November 7, 2017. The Name-in-game package will remain on sale. Anyone who already purchased any of these packages won’t be affected, only new sales will be closed. I’m closing these sales because the game is maturing and it’s coming to the right […]

I’ve just released Alpha17b, a performance hotfix for Alpha17. Steam users will get it automatically, while non-Steam users can download from their existing permanent download link (there won’t be an update email sent out). This is build 0.17.1557. When we made the targeting AI smarter in Alpha 17, we also made it harder on the […]

Alpha 17 – On the Road has been released! This version brings roads and rivers to the world, new world quests, new tools for modders, new combat tools, smarter AI, and rebalancings and adjustments across the whole design. I’m afraid that this build is not compatible with saved games from previous versions, or mods from […]

We recently asked whether players would rather have the bugfix-only update released, or if they’d prefer we just kept working and waited until we had new content to release. The results aligned with my personal thinking, which is that the disruptive effect of a release (breaking various compatibilities) isn’t worth it for a bugfix-only release. […]

This is just a quick update on what we’re working on now, since it’s been some time since Alpha 16 came out and I don’t want anyone thinking I died or became a Venezuelan monk or something. Alpha 17 is in progress. This update is going to be a refinement build. That means we’re focusing entirely […]

RimWorld Alpha 16 – Wanderlust is released! This update adds a spherical world and the ability to travel across it with multiple caravans, having simultaneous encounters on the way and settling new colonies. If you’re on Steam, your game will update automatically. Because of huge structural changes to the game, this update will break save […]

Hi everyone. We suffered a small data loss in the creative content system. Luckily we managed to recover almost everything from backup. But in five cases, we lost the corresponding email addresses of creations that need review. So we can’t notify you to come review your content. If you entered any of the below content, please go […]

UPDATE: Unstable version is being updated more or less (week)daily. The forum thread has the ongoing discussion and update details. Alpha 16 release is upcoming. If you are on Steam, and in the middle of a game, please use the Steam betas feature to set your game to the “alpha15” branch. This will prevent it from […]
