This set started a bit slowly for me, but it was getting better and better every minute.

The first mission especially required a bit of getting used to. There are some challenges you don't often encounter in an FM, while the city is difficult to navigate at first. That being said, you can already experience some new, original solutions in this first part.
The second mission is probably the most unique in the set and definitely will be remembered. You may get the feeling that the story gets a bit over the top here ("nuking the fridge" was the term? :P), but at all times you are eager to see what else it's got in store for you. Gameplay-wise the areas seemed really tight and cramped, making moving around challenging.
The third mission is the cream of the crop. The level of originality is noteworthy for an FM set in a seemingly traditional city area. You can't play a ten-minute spell without noticing something really inventive. For a huge list of objectives it also played really smoothly throughout.
The whole set brings quality visual as well as audio designs.
The little nods reminding of some earlier missions were also adorable.

Sometimes the levels were a bit confusing, for example you're never exactly sure which areas are supposed to be accesible and which aren't. Solutions to some problems are also a bit unorthodox, but this wasn't really a problem. I had one instance of a scripted conversation suddenly stopping and needed to reload.

In the end, novelty value is really high and despite a few setbacks it's definitely worth playing all three missions.
