Seven Islands is a Core Prime map that is mostly comprised of a large aqueous body, with the eponymous seven islands scattered around it in a rough heptagonal formation. As with all Core Prime maps, building a Metal Extractor or Moho Mine anywhere on the islands will generate the maximum amount of metal, rendering it unnecessary to build Metal Makers and Moho Metal Makers; despite Seven Islands being a map that was available prior to The Core Contingency, Underwater Metal Extractors will also generate the maximum amount of metal, the only other pre-Core Contingency map with this feature being Over Crude Water (another Core Prime map with water). At a size of 40 x 40, Seven Islands is the largest Cavedog map in Total Annihilation.

Unlike the other two original Core Prime maps, Seven Islands lacks reclaimable objects and thermal vents, though while the former is a non-issue due to all Core Prime reclaimable objects giving metal, the lack of thermal vents and thus the ability to build four Geothermal Powerplants on top of said vents requires a player to build greater quantities of smaller energy generators until larger sources of energy generation become available. Like other Core Prime maps with aqueous bodies, the walls of the islands are too steep for units to traverse; because of this, each of the islands has 2 sloped sections where amphibious units and Hovercraft can access the water, save for the centre-right island, which has 3 such sections.
