Expand your Underwater Cities empire with Data Era, the second official expansion that introduces data discs—a versatile new resource that can be used whole or split in half for strategic flexibility.

Manage these digital assets to construct data centers and data cities, unlocking fresh scoring opportunities each production phase. Seamlessly integrates with the base game and New Discoveries expansion, featuring new Assistants, Quick Start tiles, Metropolis cards, and upgraded structure tokens.

All existing player boards remain fully compatible, making this essential for players seeking deeper complexity and innovative gameplay mechanics.
