Adam Jensen is a failure...

Human Revolution's final hours held some fairly catastrophic events, regardless of what final choice you made at the end. Square Enix Montreal isn't saying which, if any, ending Mankind Divided will build from (and, no, it won't read your old saves). But suffice it to say that - spoiler alert - augmented people around the world were sent on a brief rampage, the Panchaea geo-engineering plant was destroyed, and the Illuminati have successfully pinned both events on 'transhuman' terrorism.

In other words, Jensen failed, and the world has turned against all augmented people because he couldn't stop the Illuminati. As Mankind Divided begins, Jensen has signed up with Task Force 29, an international police organization dedicated to fighting augmented groups that are chafing against their new position on the bottom of the social order - or, to use the terminology of those on top, terrorists. But serving with Task Force 29 is largely a means to a more familiar end.
