As brought to my attention in the following thread, Exo units within this game actually breathe: http://www.bungie.net/7_Exo39s-breath/en/Forum/Post?id=65876086#referred-Destiny%20%28Destiny%29 Now, if we wanted to make this game as realistic as possible, we should make the Exo breath smell terrible. The Exos probably run on some sort of fusion or gasoline, maybe even the "light" power from the traveller, and imo, if anything is burning it should smell, because that is realistic. Therefore, if you are in a fireteam the fireteam members should frequently comment on how stank one's Exo is and that they need to mask that stench. Same with human BO since all the humans will probably smell like dead people since they're all actually dead. Awokens are fine they look like they smell perfect anyway. Anyway that's my 2cents if you're gonna have robot breath you should make it smell like robot breath would. Good idea from one respondent: [quote]Maybe the Exos could have a green cloud that comes out of their mouth in a breathing pattern. The guardians in the city could comment about needing a mint occasionally. Since we will be wearing helmets during missions, maybe the debuff could be a green haze on the screen, or like a water-vision effect since the bad breath would make one's eyes water.
