Lord Bafford's Manor with a couple more guards and civilians, as well as a few minor tweaks and cosmetic changes. Almost indistinguishable from the original and most of these additions are only available on Hard and Veteran difficulty levels. I understand the intention behind this mission was not to change anything in the story, objectives, or design, but there is so much you can tweak in Bafford's without altering the core of the level. Skip it.
