Those of you looking to dive deeper into the Gold Award-winning Lords of Waterdeep now have the chance.

Playdek has released an expansion for Lords of Waterdeep called Undermountain. Here, you can explore the multi-level dungeons underneath Mount Waterdeep.

The expansion contains three new Lord cards: Wizard Halaster Black Cloak, "clever dandy" Danilo Thann, and Halaster's apprentice (Trobirand).

There are four new quests, new intrigue cards, an expanded game board with three new buildings, and an extra agent. That should keep you going for a while.

The Undermountain expansions costs £1.99 / $2.99, and can be bought in-game. You'll need Lords of Waterdeep to play the expansion, of course. This is on sale for a week for £2.99 / $4.99.
