The Teams expansion will allow players to enjoy Summit in either the competitive or Cooperative mode while working together with a teammate. No longer a straight take-that or survival game, players will have to plan and work together to make sure their flag remains planted at the Summit, and at least one lives to tell the tale. With new player boards, cards (Item, Event and Karma), and square "climbing ladder" tiles, the Teams expansion is guaranteed to add more depth of strategy, player interaction and more stories you will never forget. —description from the publisher
