Exo

The Exo are an emotionless race of Guardians living in the City. They are self-aware machines built during humanity's Golden Age with the purpose of protecting their creators. They have been rebooted with no memory of their original purpose, and come off as unyielding and tireless.

Development
During their presentation at the 2013 Game Developers Conference, Jason Staten and Christopher Barrett revealed the Exo as a playable race and described them as being "sinister, powerful, and tireless war machines".
