A question about paths in the game (spoilers)

[Heavenblade]

I've just beaten the game following along the triada path... and now I'm wondering about something. Are there any obscure paths, and if so, what are their requirements? What about saying as a freelance mercenary and not siding with anyone? Or even siding with SAM?

Yeah, there's siding with SAM. I saved it for last, the twist complements the other endings just nice imho. You can side with your friend Alex but he's part of a faction so it's not exactly a freelance nobody's-side path; it's the best you can do without siding with either of the Empires or the corporations.
