Main Page | See live article | Alphabetical index In the computer strategy game Starcraft, minerals are a form of monetary unit that can be used to purchase Starcraft units and buildings. Minerals can be 'harvested' by drones, SCVs, or probes. They appear as blue crystalline formations that protrude out of the ground. Being a limited resource, a game can deplete all of the minerals in the level, in which case no new units can be built. The other commodity in StarCraft is vespene gas.
