Lets say that I don't drag a knocked out enemy away, so that a patrol spots hims and starts searching for me. If I hide behind a wall where he is patrolling and is about to turn the corner, I can often get a quick take down on him, however he does say "Holy.." or "I heard..." just before so he has clearly spotted me. The same goes if I run up to someone to take them out.
Does this mean that I am not eligible for the Ghost XP award and the achievement for:
Foxiest of the Hounds (100)
Complete Deus Ex: Human Revolution without setting off any alarms.
I bring up the Foxiest of the Hounds achievement, because when I make noise to try and lure someone out, the game switches to "Alarmed" status on my HUD.
These game HUD states confuse me:
Am I correct in assuming that only the "Hostile" state means that I am no longer eligible for the Ghost.
