Loved the Catacombs in Prophesies, more in Factions?

I haven't yet gotten Factions. I was hoping to see more interior style content in chapter 2. Is there more stuff like the catacombs(pre-searing), as well as being able to go into castles, houses etc...?

Thanks

There are some areas that are supposed to be underground, such as the Undercity, and some other tunnels in the city.

The Kurzick side also has areas that feel more closed in, such as the Arborstone mission, inside a giant castle-type building. It has a courtyard and a giant hall in the middle, and some narrow passages on the sides.
