The Underworld Expansion

Worth it

Our take
Good for players who like flexible plans, sneaky bluffing, or new maps.
What you need first
Just the base game
What it adds
Two new factions (Underground Duchy, Corvid Conspiracy) and a new two-sided board with Mountain and Lake maps.
What it fixes
New maps change up the board so games feel fresh.
