Nemo Rising: Robur the Conqueror is a co-operative board game that follows the new adventures of Captain Nemo and the crew of the Nautilus, as reintroduced by C. Courtney Joyner in his novel, Nemo Rising. The game allows 1-4 players to assume the roles of the protagonists of the series — Captain Nemo, Sara Duncan, Adam Fulmer, or Ulysses S. Grant — as they explore new worlds, overcome dangerous obstacles, and complete challenging missions. As you and your fellow players work together, you can choose to explore one of two scenarios. The first scenario is the Undersea Grotto, in which you must venture outside the Nautilus to gather supplies while avoiding sea hydras, deep sea scavengers, and the mechanical Kraken. The second scenario is the majestic City in the Sky, in which you must thwart Robur the Conqueror and his army of foot soldiers, war dogs, and steam-powered creations. Special action cards and customized dice allow you to attempt dangerous tasks and overcome powerful enemies in order to save the world. —description from the publisher
