The UnderCity (An Iron Kingdoms Adventure Board Game)

[JCool]

Underrated or over-saturation - you decide. It's got mixed reviews, but I want to highlight a couple things from The Undercity: An Iron Kingdom Adventure Board Game (https://boardgamegeek.com/boardgame/175334/undercity-iron-kingdoms-adventure-board-game). The game is steampunk / fantasy, but some components might be useful if you happen to come across a copy.

Minis - fairly compatible in size with HQ, just slightly taller/bigger. Not all will work, but some may find some use.
Tiles - The square tiles and double length (and even corner) tiles fit on the HQ board on the 4x4 square rooms perfectly! Useful for pit rooms or special labs. Just fun variety in case you wanted to surprise your adventurers.
