Here they are! The Expedition Leaders have arrived to spice up your adventures in exploring Arnak’s ruins and in fighting the challenges that await in the jungle. By replacing some parts of your Arnak Organizer with the Upgrade Kit, you will be able to store the elements of the Expedition Leaders expansion in the base game box. With the new card stand, token tray and expansion boards in the box, there will be a 5 mm lid lift.
