That Old Adage

That Old Adage is an achievement/trophy in The Missing Link DLC for Deus Ex: Human Revolution. It requires the use of the Social Enhancer cranium augmentation while talking to Garvin Quinn just before leaving the Rifleman Bank Station at the end of the DLC.

No matter what form of manipulation — Alpha, Beta or Omega — you try, they will all fail, but yield the same interesting new insight from Quinn, who is really trying to be honest with Adam Jensen, about his role in the matter.
