Spring is a cooperative game where players work together to overgrow a city. The Biological control unit is destroying any unauthorised biological growth in the city, all of our natural spaces have been destroyed. We must band together and overgrow the city. Play cards to grow plants in your district, trade cards with your friends and purchase actions needed to accelerate growth. All while the BCU moves around the city removing our plants and gathering evidence to shut down our greenhouses. —description from the designer
