The map has very few reclaimable features, all of which are located in the large central section, though it is often not necessary to reclaim these features as they all give metal, a resource which is naturally abundant on Core Prime maps. Because Over Crude Water is a Core Prime map, building a Metal Extractor anywhere will generate the maximum amount of metal possible, which also extends to building Underwater Metal Extractors in the varies bodies of water, a feature not available in non-Core Prime pre- Core Contingency maps. The map has the appearance of a large maze that's made up of many narrow interconnecting metal bridges and a large metal section in the centre, with smaller sections situated at its edges and corners.
Over Crude Water is one of the three Core Prime maps that came bundled with the original version of Total Annihilation, the other two being Metal Heck and Seven Islands.
