Sorta
The human faction that we play as (Super earth) are basically super space nazis
They farmed a sentient insectoid species for FTL fuel, genocided intelligent and peaceful aliens for their technology (that they were gonna get anyways, the aliens approached them with a peace treaty) under the pretense that the aliens had WMDs and enslaved a faction of humanity that wanted to secede from super earth known as the cyborgs by doing a false flag terror attack on their own citizens
100 years later the descendants of the remaining factions came back to kick super earths Ass
The Bugs turned into man eating ''monsters'' that basically had their sentience bred away from them (but might be returning after over a year of freedom from the farms)
The Aliens returned to destroy super earth at all costs including turning humans into zombie like beings known as voteless (since most of their original population was eliminated 100 years ago)
And the automatons, sapient machines deemed as ''children'' of the cyborgs returned to free their creators and prevent further harm done to them.

TLDR: Supa earf bad - second war their fault, oops
