This is an excellent playthrough video by prenatual I found on YouTube. All credit goes to him.

Deus Ex: Human Revolution. The Missing Link. Factory Zero playthrough.
Perfect ghosting (no enemies alerted). No take-downs (except "the boss room"), no aug upgrades, no weapons, no items (except quest-related). 'Give me Deus Ex' difficulty. 9/10 achievements earned (except That Old Adage, which requires CASIE aug).
