A Civ4-rendition of the SMAC unit - the Locusts of Chiron:
It's a swarm of flying worms - paralysing people telepathically... to eat their brains!
Model just consists of a couple of particle emitters, generating a cloud of insect-like things. File includes custom animations, effects and sounds for the locust unit, as well as instructions to implement it into your XMLs.
Also included is a version without the red telepathic wave, if you want to use it for a more "conventional" swarm of insects.
Made for the Planetfall mod.
