On an ocean world, even enemies must play fair. You and your rival compete for control of the four flotillas, the last remnant of old Earth. Strike cunning deals, build stable ground, and clean the ocean. Then, you will truly lead Seastead!
With the survival of humanity in the balance, sabotaging your rival outright would put too much at risk! So in Seastead, many of your actions will also help your opponent; you just have to make sure you don't help them too much.
Each turn, you either dive to gain resources or build a building from your player mat with your resources. Whenever you dive, you draw a card with two different resource collections from which to choose, with the resources you don't pick going to your opponent! When you construct a building, add it to one of the four central flotilla tiles, opening up bonuses and abilities — just try to use them before your opponent can!
Seastead contains double-sided flotilla tiles, a variety of specialist cards, and multiple building paths to create endless strategies to explore!
