Anno 1800: Sunken Treasures is a story add-on for the real-time management strategy game Anno 1800. The queen has disappeared, and Sir Archibald Blake requests an expedition to search for her. As you progress, you will unlock a new region — Cape Trelawney, in the same biome as the Old World. This is a large map with resource-rich islands.
The add-on requires the original version of Anno 1800.
