Well we got Anarchs, Criminals, and Shapers. But with 3 new factions what are the names of the new factions?
So here are my guesses at lore
So the security specialists I can only guess Grey-hats. At first runners were classed as black hat for criminals and white hats as specialists that test system and develops ways to prevent intrusion. Since more and more corporations are becoming the law (either through lobbying or just ignoring government laws all together) many so called white hats are no longer devoted to upholding injustice through corrupt governments.
As a faction that has no humans just self aware AI constructs We could call this the Skynet faction. Like skynet from terminator they want to end humanity and take over as the next evolution of sentient beings starting with the net. They care nothing for the downtrodden like some anarchs, these beings care about power and will start by attacking the human power base, the megacorperations themselves.
Don't know what to do about this runaway bioroid faction. Not too many runaway biroids as they can all be tracked not to mention their program insures loyalty to whoever owns them. The runaways. There could also be some humans in this faction as those that harbor runaway bioroids. Unlike shapers they don't consider bioroids as tools that become obsolete and must be replaced.
