In a Kickstarter update on October 22nd, 2015 (#87), Tørnquist revealed that the initial internal plan was to release Book 4 on October 21st, which would have been the anniversary of Book One's release. On November 30th, Book Four's trailer was released, with a release date set for December 3rd, 2015. When that day came, RTG managed a smooth episode release with Steam and GOG releasing almost simultaneously shortly after 3 PM CET.
