Owlcat Games revealed what the big surprise was: a very big patch for Pathfinder: Wrath of the Righteous. It is actually so big that they released it in the beta branch first!
More information.Update 1.1.0 (beta)
Crusaders!
We've prepared a huge update for you! But because it's so huge, and because of various issues you may encounter with it, particularly with mods, we are releasing it in the beta branch first. Please switch to it in the properties of the game in Steam to download the update.
Because the list of changes is HUGE, we couldn't fit it here, so we put a link with the full patch notes instead.
Let us know what you think!
