This reminds me of something I read last week about a Russian Tycoon who believes we will be able to achieve immortality. Check out the link above for more about this idea^ "Russian multimillionaire Dmitry Itskov predicts that the human race will achieve immortality within 25 years as a result of minds being transferred into computers, and that robot bodies capable of housing human brains could even be available by 2025." Now imagine this idea many years in the future where we have this ability to its full potential. Exo's could possibly be some of the strongest guardians who we could not afford to lose. Exo have been described by Bungie as "sinister, powerful, and tireless." In terms of player design, Bungie drew its inspiration for the Exo from such sources as the Master Chief, The Terminator, and the undead. - [url]http://destinypedia.wikia.com/wiki/Exo[/url] I am intrigued by the Exo's and their place in the Destiny Universe.
