It sounds like Eidos Montreal isn't leaving anything to chance; a "powerful, layered" plot is promised for the third game - which has been confirmed as a prequel set in 2027- and the dev has even drafted in the consultative talents of original writer Sheldon Pacotti, while also gaining the blessing of both Harvey Smith and Warren Spector on the project.
You're cast as average joe Adam Jensen, who works as a private security officer at a technology lab specialising in biomechanical augmentations, a forerunner to the sort of nanotechnology shown in the original Deus Ex. One day the path of his life is unexpectedly altered as a team of black ops commandos break into his company's HQ, and using a security plan from Jensen's own hand, a mass slaughter ensues and the conspiracy begins.
"Deus Ex 3's vision of the future sees holographic screens flicker atop ferries moving back and forth in front of the Shanghai skyline, now split into two layers with the rich on the top and the poor in perpetual twilight below," says PCZ.
Eidos Montreal says it's more than aware of fan reaction to controversial second game, Invisible War, and promises mistakes, such as limiting ammo types to just one, won't be repeated.
