Keeping the spirit of the award-winning game Small World, Small World Underground continues by putting a new spin on the game play. Small World Underground includes 15 fantasy-themed races of creatures along with 21 special powers.
Each player will control several creature/power combinations over the course of the game – spending points to draft these combinations – and will use those creatures to claim control of various subterranean locations.
Some locations hold relics or are designated as "places of power", and monsters must first be conquered before a player can claim these special benefits. At the end of each turn, a player scores points for the regions he holds, and the player with the most points at game end wins.
