In the year 1996, the tectonic plates shifted and destroyed an underwater city. With the city abandoned, two nations fight over the remaining resources. Each player controls a submarine. Players must build their decks by combining sea life and scrap in order to destroy their opponent. Tectonic Shift is a multi-deck-builder where players build 3 decks at a time. Cards provide different functions and uses depending on the deck they are added to with the goal to deplete your opponent’s health down to 0 to win. —description from the designer
