As of now Knight's End is in 1.0.
However this is not the end.
The game will enjoy a few months of active development post launch, as well as the "Final Step" as a free dlc/content update, which will conclude the whole series in a climactic finale, as well as two more summons to collect.
Additionally the game now has its achievements unlocked, and available to collect.
Once the post launch work is completed, I will be moving on to Usurper to touch up the game, a process I plan to do for Into the Fray, and Moonless Knight too, in preparation for the future.
After that, hopefully I will be able to start on Border, the new series that serves as the sequel to Skautfold separated by thousands of years and quite a few light-years.
