Drone

The drone is a zerg breed.

Info
If the player spawns a drone, it will immediately generate a hive, hatchery, or lair. The structure will spawn with its own mineral fields and at least 2 extractors, which the drone will begin extracting. As more drones are produced by the hive, they will join and harvest minerals and vespene gas. As time progresses, drones will produce more structures, which produce more zerg breeds. More hives will be created, soon the drone population will have reached into the millions, or even billions before dominating an entire world. The zerg will continue to extract the minerals and gas until they are depleted. If an entire world is taken over, the zerg will open portals to other worlds, and take drones to the new world on board leviathans or behemoths.
