Nucleum: Gibraltar

To prepare Nucleum: Gibraltar, replace the base board with the new maritime map. Set aside standard Prague-specific action tiles and contract pieces, replacing them with the Gibraltar expansion components. Distribute specific player boards, ship tokens, and special maritime markers depending on player count, ensuring neutral ships are properly placed along shipping tracks as dictated by the setup cards.

The main objective is to establish a dominant industrial network centered around Gibraltar. Players must integrate maritime trade routes, naval contracts, and specialized urban buildings to expand their reach across the board and achieve victory.

During a turn, players perform standard worker-placement and network-building actions. The Gibraltar expansion introduces shipping mechanics where players pay thalers to place ships on sea routes, enabling the import of coal and uranium. Special tied action tiles allow chained moves, though strict resource management remains crucial.

Scoring revolves around fulfilling military contracts, activating new technology tiles, and utilizing special municipal buildings. Players also gain bonuses from naval positioning, regional dominance, and milestone markers achieved throughout the game.

The game concludes when players satisfy expanded end-game trigger conditions, which require more milestones to be met in multiplayer setups than in the base game. Final scoring tallies all accumulated points, including bonuses from the Gibraltar module.
