"Rodamill" picks up (almost) right where "The Shipment" left off. Having shut yourself up in a box inside of a Mechanist warehouse, you eventually come to... in the ruins of Rodamill.
This mission and its predecessor are structurally pretty similar, in that they both involve a journey from point A to point B across a city landscape... but the contrast is striking. As you begin to explore Rodamill, which has the haunted look and atmosphere of the Old Quarter, you quickly realize that something more sinister than an earthquake befell this town. Mechanists patrol the streets and write of clearing them of beasts, and there's still a few lurking around indoors, and not just beasts... The city is also significantly larger than the previous one. There are more and larger side areas to explore, with plenty of multi-storey ruined buildings and more parallel, interconnected streets. As with "The Shipment," the level of polish and detail is very satisfying, and the more open, exploratory progression is even more suited to my taste. There are also a few nice surprises in the form of scripted events.
I enjoy Old Quarter-style missions featuring ruined cities overrun with undead, but "Rodamill" provides a unique opportunity to explore one as it's in the process of being cleared. There are still threats on all sides, in the form of patrolling guards, but the "other" horrors are not completely gone either.
Unfortunately, once you reach the mine, the mission—and the campaign—is basically over. Morrgan never finished the project (and in fact only completed one further, unrelated mission a few years later, released in 2008), so we can only imagine what the Greyfeather estate might have been like, and what answers about the mysterious disaster that ruined Rodamill it might have contained. Even so, the two missions that we actually got are well worth checking out.
The fact that there is no followup to this insanely good mission is one of the biggest tragedies in FM history to be honest. I haven't played this mission in a while but I remember the mines in particular being spectacularly creepy.
