Leonida Keys

The Keys are Leonida's island chain: marinas, stilt houses, sandbars and a long thread of bridges connecting them to the mainland. They appear repeatedly in official footage, usually from the water or the air.

The obvious implication is that boats and seaplanes matter here in a way they never quite did in previous games — a chain of islands is a very deliberate thing to build if you do not intend people to travel across water.
