The Clockwork Expansion 2 is a standalone expansion that lets you square off against four automated factions. Add one to round out a game with few players, or team up in cooperative play! Each bot has four difficult levels and four trait cards, giving them special powers and strategic quirks. Also included is a new Better Bot trait card for each faction from the first Clockwork Expansion. This is an expansion. It requires the Root board game as well as one or both of The Riverfolk Expansion and The Underworld Expansion.
