The Alien Commander is the Kharaa hive mind that governs over territory expansion and species evolution. Any Kharaa player as any lifeform can become a commander by pressing the Use key at a grown and unoccupied Hive, which will retract its tentacles from the Tech Point to indicate occupation. Only one commander may exist at any given time, and the Alien Commander may exit the Hive as his previous lifeform at any time; if an occupied Hive is destroyed, the Alien Commander will be ejected without harm as his previous lifeform.
The Alien Commander has an overview of the map, as well as a commander user interface to allow interaction with the world. The Commander menu consists of the Mini-map at the bottom left, Resource counter centered on top, Log Out button at the top right, the Unit status and Tabs menu at the bottom right.
The Kharaa Tech Tree contains the technology progression paths available to the Alien Commander. It is a centralized progression system dependent on research and base expansion.
