"Eradicate an entire creature species to make way for something new."
The Species Eradicator erases the species it was used on from the planet. Upon taking effect it opens up a foodweb slot. It is quite useful if you wish to supersize a creature. Unfortunately, it cannot be used as a weapon or to speed up elimination of tribal/civilisation creatures if you want their planet, because sentient species are immune to its effects. It is odd to call it a social tool, as with the Creature Tweaker and the supersizer.
This tool uses purchased ammunition.
