RimWorld Update 1.1.2654 Is Now Available, Complete Patch Notes Here


RimWorld is almost four years old, and even today it is getting post-launch support. The developers at Ludeon Studios recently released a patch, titled Update 1.1.2654, that focuses heavily on the previously released DLC, Royalty. However, some aspects of the main game were also touched.

The update has reworked the destruction of smaller buildings. From now on, smaller buildings will generate steel on destruction rather than giant slugs. Every Empire pawn will be at least named as Freeholder, and you can also create player-created names. A toggle for anima tress has also been made available.

The updates make tons of changes, and you can read all about them below and on the official site.

  • You can now configure a desired psyfocus level on your psycasters and they will meditate enough to maintain it, without needing to use the schedule.

  • Player-created names update.
