Does anyone know if an enemy discovering the body of one of his sleeping comrades counts against you for a "Ghost" run? i.e. Not if they get any bolts in the 'detected' meter over their head, but if they just see the fellow thug/guard/etc and say something like "Hey! Wake up!". I was just wondering since it seems to show this stat on the summary screen after a mission and I thought this might mean it's important.
Basically, as long as no red 'marker' appears on an NPC or a wolfhound (dog), it won't count as detected. Three white 'markers' won't count as detected. The red marker appears only if an NPC or wolfhound has detected you, not a body you killed or made unconscious.
Also, here are some reports from other posts:
Bodies found does not void the achievements Ghost, Clean hands or Shadow. Completed all three achievements yesterday and I have had missions where bodies were found.
