Yup, it's a good challenge for anyone that finds the base starcraft missions to be too easy. I put a link to the download page in the video description if you want to check it yourself.
Some of the missions will have some of the broodwar units available, but the enemy gets broodwar units too (like dark archons mind controlled my lurkers in this mission). The focus of this hard campaign was more on difficulty than lore accuracy, but most of the missions will still have restricted units.
