A server mod, where metal extractors can be built anywhere, but factories can only be built on metal spots. The idea is a simple interpretation of zone control mods of prior games, where map control is vital. Factory composition is important as you are limited on factory count. Reclaiming tier 1 factories to build tier 2 factories is likely. Assisting factories is important later on, but still limited due to rolloff time. This mod can use any map, however some are not ideal as the metal spots can be too close to use all of them. I've made a few ugly as sin but balanced maps with this mod in mind: https://forums.uberent.com/threads/factory-point-maps.67234/
