Consciousness is Over-rated is an achievement/trophy in Deus Ex: Human Revolution. It is earned by knocking out 100 non-civilian enemies within one single playthrough of the game.
Knocking out means to render an enemy unconscious with one of the following non-lethal means:
- Performing a non-lethal take down on a human enemy.
- Assaulting a human enemy with a stun gun, a tranquilizer rifle, a gas grenade or P.E.P.S.
- Using an indirect means such as throwing or shooting at a gas cylinder, which releases a gas similar to the one produced by a gas grenade or by tricking the enemy to walk directly into a gas cloud.
