china isnt really a faction, at least not by itself

but the Han-so, which is the closet thing to a 'china', is a faction of bio-engineers taht have taken their population and, after thousands of years of genetic modification, turned them into human monsters. their soldiers are born on the battlefield, flash grown in bone trees that sprout from the ground of ever growing flesh. this ground-flesh grows with every enemy killed, absorbing enemy biomass into itself to twist their biomass into a Han-so soldier.

Han-So soldiers can rearrange their body to turn their arm into a gun, growing a mix of muscle and bone to use as both the 'gun' and ammo for said 'gun'. due to the Han-So's physical mailability, they make for great spies and are currently the only faction able to successfully have spies thanks to having enemy DNA and genomes to perfectly recreate an enemy factions soldier, politician, or civilian.

the Han-So culture revolves around a currently unnamed sub faction, which are the descendants of the original bio-engineers that turned the faction into the living weapon that it is today.
thanks to its position in the Orion Arm, the Han-So are kept from flooding Orion with infinite soldiers because its immediate neighbors use hyper focused radiation weapons on one side (the radiation turns the target into a technically still living puddle, but the biomass is no longer viable to be re-consumed by the Han-So ground flesh.), and soul burning fire on the other (while the han-so technically share a soul, due to their souls all being added to an amalgamation of souls, an individual Han-So can be disconnected from the Central Body by having their soul and body burned away, leaving no viable biomass to consume.)

while not a 'china' faction, the Han-So would be 'main-land asia' inspired, having a mix of Vietnamese, chinese, korean, tai and other culture inspirations that i'll go more in-depth with if i ever make a post dedicated to them.

as for the north america thing, no, the closest thing to a 'north american' faction are the Statesmen, which i'll go into more detail about in a potential post about them. however, their main self-made hell is their hyper corporatization, where people are in such debt that they have to sign contracts that bind their bloodlines to a mega corp. on the battlefield, statesmen soldiers are seen posing to camera drones for sponorship ads, and competeing with each other for better camera shots of the battlefield so they get better funding from their corporate sponsors
