Catan: Traders & Barbarians (5-6 player extension)
Traders & Barbarians is distributed as the third major expansion for The Settlers of Catan, although it is actually a compilation of small expansions and variants. It is independent of the Seafarers and Cities and Knights expansions, but can be combined with them.
This is the 5 and 6 player extension for Traders and Barbarians to allow you to add up to two more players.
(Requires both Catan base game and Catan: Traders & Barbarians to play)
