Ark Nova: Marine Worlds, an expansion for Ark Nova, introduces several new elements to the game, such as marine animals, each of which must be played in new special enclosures that need to be built next to water.
About half of the marine animals are reef dwellers, and when you add a reef dweller to your zoo, you trigger the ability of all reef dwellers in your zoo. To manage the thinning of the card deck, which naturally occurs by adding more cards, all marine cards have a wave icon, and each time it appears in the display, you discard the first card in the row and then refill.
A new fourth university is available on the association board, and if you take it, you require one of six special universities from the reserve that has a research icon and one of six animal icons. When you take this register, you reveal cards from the top of the stack and keep the first revealed card with an animal icon that matches your chosen university.
For each of the five action cards, there will be four alternative versions with a slight twist. Players select action cards at the start of the game, replacing two of their standard action cards with these new ones, increasing the asymmetry in the game.
New bonus tiles and victory points cards are also included.
Additionally, the expansion will include alternative tree markers for the 3 tracks and cute animals to mark the conservation projects you support, instead of using your regular player markers.
