When starting single player survival mode i do not get any faction missions for talons or megacorp. I thought that i have to play along to get them, but nothing happens. I can see only the story mission and credibility missions for all factions i discovered, but not "privacy matters" for megacorp or "pest control" for talons. Is it supposed to be so???
Not sure if this was intentional, accidental or deliberate - but I've noticed this as well. These may have been disabled so we can focus on the story missions to ensure they're working correctly, removed to be replaced with new missions later, or simply removed as they are rather dated and don't mesh quite so well any longer... I've no idea, just some guesses.
