[@Liotrent]  I was thinking more along the lines of the Zerg and the Borg when I made them. I didn't really play enough halo to get a sense of the flood. I also imagine that, given the setting, it'll be hard for them to go unchecked long enough to get the numbers to fight like any of those inspired source materials. I intend to play them more information warfare style with a gross ambivalence to suffering. Armies are just as often defeated ideologically as they are militarily after all.
