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!
