The Hitac-Mothership is a Alien only available during the Hitac Event. These aliens are fairly large and inflict massive damage upon any nearby ships. Each Hitac-Mothership has six Hitac-Minions attached to it, and is protected by an Insta-Shield, meaning only when the six Hitac-Minions are destroyed, could the Hitac-Mothership be destroyed.
The six minions and mothership combined together dealt a massive, and unseen damage from any other Aliens, of 90,000+. The mothership also has a new and unique ability to jump from map to map. It cycled around the Lower Maps, and first spawned in 3-4.
