Are they split into several factions?
The articles I read so far always lumped them together, never mentioning any group specifically.
Anyways, I don't mind working for the corporations either if that gives me an opportunity to undermine them and stab them in the back when they least expect it.
Yep. There are multiple Nomad tribes, some small, some millions strong.
I should probably do a poll for factions not described by CDPR so far, but that would be -real- speculative. Trauma Team, Orbital Air, Aldecados, Wraiths, etc.
