Underwater Cities: New Discoveries
This expansion adds new components and options to the base game, introducing alternate strategies and setup changes. Players gain 52 new cards that expand available actions and development paths, plus new assistant tiles with unique abilities to differentiate each underwater nation. Starting resource tiles let players begin with construction already in progress, accelerating early play by roughly one round. New player boards and reprinted upgraded boards support several variants, while green metropolises provide variant-specific benefits and fresh strategic choices. A communal museum mechanism lets players discover and display artifacts to score prestige for their nations.

Carlos4.0 Real player boards and asymetric assistants should have been included in the original game. The other modules doesn't add any particular mechanic to the game.

Rules questions
Answered from the rulebook by Ludoya's rules assistant.
With Quick Start, do we still take the normal starting resources and play round 1?
No. Starting resource tiles replace the usual starting resources; choose them in reverse player order after drawing six cards, then begin in round 2, skipping round 1 (p. 4).
When do I choose my new Personal Assistant, and does its special ability depend on being able to use its action?
Choose one of your two assistants before your first turn and return the other to the box. Its lower-half special effect is separate from its action-card ability and applies even when that action is unavailable (p. 4).
Can we use player boards from different sets in the same game?
No. Everyone must use boards from the same set; assign boards randomly within that set (p. 2).
When I build on a discovery site, do I get both the discovery tile’s benefit and a museum reward?
Yes. Reveal and immediately gain the discovery tile’s benefit, then place it in the museum and gain the reward for that space; the first discovery, for example, gives you two cards (p. 6).
If I’m the first to reach a museum level, can I block a reward space for later players?
Yes. The first player to reach a level chooses among its four rewards and places their discovery tile on that space; it is unavailable to players who reach that level later (p. 6).
If a metropolis is on a doubled-effect site, are only its immediate effects doubled?
No. The doubling applies to all types of metropolis effects, including immediate, Production, and end-game effects (p. 8).
