The Borg Unicomplex is an extremely large Borg-controlled space station, a vast array of connected Borg technological habitats that is used as a command center by the Borg Collective. The most well known Unicomplex is Unimatrix One, which serves as the Borg Queen's Unicomplex at the heart of Borg space in the Delta Quadrant. Unicomplexes have thousands of connected components, modules and other structures, including hubs for hundreds of Borg starships and billions of Borg drones. (ST video game: Conquest)

The Borg Unicomplex was an unlockable skirmish battle level in Conquest.
