I cant remember the names of the missions I played as its been a couple years. The mod also has been
vastly improved since I played it. Im waiting for the standalone version to take another spin through and play a few more missions. With that said and from when I played it and the few missions that I played, I will say that they are better than some of Thief 3's levels. The missions have a better sense of throwing you to the wolves. Its like "heres a fort get inside and loot/complete objective" and you figure it out.
Since its community made missions, some are great and some were pretty bad.
You can look up the best missions considered by the community and then watch maybe one of them on youtube.
