This is a pretty great, if not straightforward mission. Very impressive level design considering it was the author's first foray into Dromed. It's a pretty small map, but you wouldn't be able to tell with how much ground they packed in to it, and they do a great job of capturing the windy, twisty feeling of the City streets.
Something to beware though, if you're only playing on Normal difficulty then you'll be completely locked out of the Cathedral grounds. Pretty sure it isn't a bug or I'm not missing anything, since I've been poking around for a while now and others have said the same on TTLG. I wasn't going to start the whole mission over just to gain access to it, so unfortunately I wasn't able to finish the mission at this time. Might come back to it later. Just keep that in mind if this is your first playthrough!
