Gene-stealer queen ant

Little is known about Formica Ereptor. Its unique parasitic life cycle depends on particular neighboring ant species for its survival and so there are few habitats where it thrives. Gene Stealers are nomadic; new queens fly great distances from their birth colony, then spend the first year of their lives travelling back home across the land.

Over the course of her journey, the queen will harvest the DNA of other ant species she encounters so she may bring new diversity to the birth colony. She also makes use of the assimilated species along her journey, allowing her nomadic tribe to adapt to the dangers of the changing environment.

The Queen in game does practically nothing except store the eggs for the colony, in the genome tab she can get some pretty useful abilities to either heal herself up, confuse the enemy and more.


  • The name Formica Ereptor etymologically means 'thief ant'.
  • Formica Ereptor is a fictional species created by the developers in order to incorporate more ant species into the game. Originally they planned to keep the game as true to nature as possible, but had to work around the polymorphism to make the game more viable as an RTS.
  • The gene-stealing ability is similar to the Xenomorphs from the 'Alien' franchise, which are parasitoid lifeforms that take traits from their host.
    • The gameplay of EOTU is also notably similar to the Xenomorph campaign in the PS2 game "Alien vs. Predator: Extinction".
