How to unlock the Opportunist achievement in DEUS EX: HUMAN REVOLUTION - Definitive Guide
"Knock out 100 enemies in a single playthrough." achievement. you must have at least one battery cell charged to perform a takedown and if you have the upgrade where you can take down two guys at once this goes by pretty quick.
p.s.
make sure you dont get seen as they will blow your head of
Takedowns are performed by sneaking or going up to a target, and tapping . This will disable the target but will not kill him/her. Holding however will perform a Lethal takedown, which you do not want if you're going for Pacifist. Only takedowns performed on enemies (those that turn alarmed/hostile-on-sight or are quest-scripted) will count, not Civilians.
If you have not achieved this by the time you arrive on Panchaea, then knockout all the residents who have gone mad as they are considered hostile threats. Credits Wolfwood.
Just remember if you're going for one playthrough, you must only use none lethal takedowns (tap ). Doing so will not void the 'Pacifist' achievement and will also increase the counter for the achievement 'Consciousness is Over-rated'.
Right from the first mission, you'll be introduced to how to take people out, so from here I'd recommend you try and get your 50 takedowns as and when you can. If you see an opportunity, then take it but don't rush. It's easier to do this achievement at the beginning of the game rather than later on when it could become more risky for you.
