|Contain the Citadel core without killing any stalkers.|
The stalkers that you can't kill are the two that are below the core. They are the bony skinny looking guys. Just don't kill them and shoot the energy balls in the opener things. Be quick because these guys disable them right after. When the core is contained and your gravity gun goes back to its original self, the achievement will unlock.
