Episode 1 of Bones sends Garrett to pull off a heist in a dockyard, which just happens to be located in a snowed-in section of the Old Quarter that was recently cleared of undead and reoccupied by the living. Much of the place is still abandoned though, and part of town is still in the undead's clutches.
This mission is the first level of a campaign that apparently never got more than off the ground. There was no Episode 2 or as far as I know any other missions by the authors. And Episode 1 does bear the marks of an unfinished story. There are texts that seem to hint at story developments that never come. One of your objectives leads to a twist that leads to a cliffhanger that never resolved.
That said, there's plenty to enjoy about this mission that stands alone. There's a sizeable chunk of city to explore and a number of objectives to pursue, and always more than one way to pursue them. In fact the mission is very good at providing alternate pathways to a given area, whether on street level, above it via ledges, beams and pipes or through windows, and occasionally underground.
Aside from the requisite crypt, only certain sections of the city are still completely ruined and inhabited by the undead. The more populated sections are composed of a mixture of still-abandoned buildings and those into which some brave soul has decided to move. Either way, there's plenty of reason to explore. Guards patrol the streets in large numbers, but for all that it's never terribly difficult to shake them off.
Despite making promises it can't keep, Bones Episode 1 is a very solid mission, well worth your time.
It's a very interesting mission because it really, really looks like a lost mission from Calendra's Legacy, using mostly the same texture selection, similar sounds and built very similarly to both A Meeting With Basso and Midnight in Murkbell. I think it's a fantastic mission and it's crazy the author tried to make it under Olddark when you consider the sheer scope of it.
Having played those missions I can totally understand your comparison. This mission is like the theme of the above-ground section of "A Winter's Eve" combined with the more open-ended city layout of "Midnight in Murkbell."
