So originally I was thinking that the factions were more groups that developed during the Golden Age. Groups that settled on different planets and installations. With the fall of the Golden age they retreated to Earth and are now fighting for territory in the City. The FOTC (Forces of the City) are the Guardians. The Factions are trying to recruit Guardians to strengthen their forces. However, yesterday this screen shot was released and it clearly shows both the Osiris and the Dead Orbit logos on the gun and the Dead Orbit logo on the helmet. I am now leaning more toward the theory that they factions are actually corperations and you can purchase gear and weapons from each company and that each company will have different concepts for their equipment. what are your thoughts on this?
