Ahoy, you man-beast slaying tyrants, I bring great news!
After a long time(and a ton of effort), we at last implemented Steam Workshop support for Rooks Keep.
Now there may be a few issues, and some things to improve over time, but otherwise everything is working perfectly.
Be sure to read over the guide we put together over on the Viscera Cleanup Detail forums to see how it all works.
Steam Workshop Publishing Guide
We'll add more info and the like as the need arises. As well as migrate the guide to Rooks Keep.
For now though, tear into that beast like a Knight who's nibbled on a few too many mysterious woodland herbs!
Thank you all, and make sure the arenas of old(and hopefully new!) are kept well stocked with fresh blood.
