Here are some details of the upcoming patch. There will be a new playable character class called the Ratkin Plague Blade. He is a tough warrior with abilities focussed around spreading disease. There will also be an option in the team selection screen that allows you to fight with a smaller warband.
Other changes include some balance tweaks for various character classes, some improved lighting effects and a change to the Hard difficulty to make it a little less difficult.
The patch is in final stages and should be out either today or Monday at the latest.
UPDATE - Update 1.81 has been uploaded. Please let me know if you find any issues or bugs with this release.
