As the networks of Underwater Cities have increased in size and complexity, there is an increasing need to manage the data required to keep them running optimally.
Underwater Cities: Data Era is the second expansion for Underwater Cities. This expansion introduces a new resource for players to manage - data discs. Unlike the other resources in the game, data discs can either be used whole or can be divided into two halves. Players can divide their data discs into halves any point in the game.
This new resource will provide players the opportunity to take additional actions as well as to use them to build data centers, a new type of building in the game, and even a new type of blue-domed superstructure ? data cities. These new buildings and cities will offer players new ways to score points during each production phase.
This expansion can be combined with the base game and with the first expansion, New Discoveries. The new Assistants, Quick Start starting resource tile and Metropolis tiles from this expansion can be used together with the New Discoveries expansion. All existing player boards can be used with this new expansion as well.
This expansion also includes upgraded structure tokens that can be added to the game.
