I have compiled multiple screenshots and managed to create a complete map of Nessus that is fairly clear. I also added a legend to show what the different symbols mean. It uncovers some interesting details like the fact that the room behind the VoG-like door is not actually a Lost sector (as many people think) but is in fact a Story Mission and the actual lost sector is located directly beneath the Lost sector sign found in-game. could anyone figure out what the icon I have labelled as '???'. http://imgur.com/a/wFOnO Edit: I will release a revised version with more details if enough people like what I have done Edit 2: Could anyone figure out what the icon I have labelled as '???'.
