As Paper isn't placed on the map, it needs no improvement and unlocking technology.Īll units and buildings that need a strategic resource use one copy of it, the only exceptions being the Agribusiness (using two Horses) and the Nuclear Missile (using two Uranium). To obtain them, they need to be improved by a worker or work boat. Initially, they are not visible and become so when certain technologies are discovered.

There are seven strategic resources, six of them are found on the map. Unlike other resources, they come in a quantity specified on the tile they appear on and add to a stock of that resource that you can use to trade, build units or buildings with it until it is depleted. Most of them are found on the map, but can also be obtained by other means.

Strategic Resources are resources that allow you to build some units and buildings that require them.
