Shadow Politics is deceptively simple. It feels like your average Thief 1 mission. At the same time, it goes in a direction the OMs never went.

MINOR SPOILERS:
The focus here is not on a big complex building, but on the streets and what you can find in them. Using Rope Arrows leads you to all sorts of small yet interesting spaces, where loot and lore can be found. The lore really adds to the Thief universe, as you may have glanced from the briefing.

But my favorite part of this mission is how it leads you to unexpected places, that are in no way related to the big main objective. They are pretty important if you want to meet an Expert loot threshold, however. The embassy itself is actually one of the less interesting parts of this level. Visually, it's stunning. It might be the most rich-looking building in Thief Gold (if you would put it in-between Thieves Guild and The Sword, which is where it takes place story wise). Yet its layout is pretty simplistic. Still, it's still an enjoyable - and tense - place to be in.

Overall, this is probably the best fan mission I've played yet.
