The Hive fleets are quietly drifting between the stars, looking for their latest planetary prey, while incubating huge hordes of tyrannical cubs.

If they encounter particularly hard prey, Hive Mind releases hordes of its greatest monsters to completely destroy it – a group of creatures that the dismayed survivors call Crusher Stampede.
