Aldebarans describe themselves as "master scientists and conquerors." Their tactics are to create subterranean bases within small planetoids and send them drifting towards inhabited worlds with "gravity motors." As these "War Worlds" approach the planet, the Aldebarans launch an armada of fighters and bombers, while the planetoid smashes into its target. The Armada is able to defend the planetoid as it meets its target, and clean up surviving resistance forces after the catastrophe of the impact. Aldebaran technology includes holographic projectors,
energy blasters and the ability to decode alien languages. They attack the earth in the year 2488, but are repelled.
