Abyss Abyss is a game of development, combination and collection in which players try to take control of strategic locations in an underwater city. To achieve this, players must develop on three levels first by collecting allies, then using them to recruit Lords of the Abyss, who will then grant access to different parts of the city. Players acquire cards through a draft of sorts, and the Lords of the Abyss acquired on those cards grant special powers to the cardholder but once you use the cards to acquire a location, that power is shut off, so players need to time their land grabs well in order to put themselves in the best position for when the game ends.
