I liked this rework of the original campaign. It's much simpler, reworking the basic concept of the undead tech tree, etc. I also liked, when I met units, that are different faction by faction (Footman -> in Dalaran: Sentry, Etc.). There and there are few bugs (you can't convert Acolytes to Shades example), but there is no game or campaign breaking bugs. I also forgot for the first two chapters, the campaign is recommended to play with 1.29, not with 1.31, but that's my fault, and yes, if someone does not play it, with the recommended version, than there is a campaign breaking bug : build 3 Ziggurats in the chapter 2, I completed every objective, and I cannot process towards chapter three, because the game does not sensed the ziggurats that I builded previously, so I cheated once again... Thank you for the fun, I liked this perspective of yours with the undead.
