Whispers of Conspiracy

Chapter 7 - Maneuvers in the Dark Sent to Highland Park to investigate a signal, Jensen discovered more than he bargained for: a secret FEMA facility temporarily occupied by black op mercenaries -- the same mercenaries who left him for dead six months ago. Forced into combat with a soldier named Barrett, Jensen proved victorious, emerging from battle with a corpse on his hands and another possible lead: an apartment complex in China named Hengsha Court Gardens...

M11 - Whispers of Conspiracy is a main mission in Deus Ex: Human Revolution and the last to take place in Detroit part 1.

Meet Pritchard in my office
Pritchard explains the transmission. 1000 XP. Opens up the secondary objective.

Meet Sarif in the Penthouse
Jensen meets William Taggart and Isaias Sandoval beforehand. Sarif will give Jensen the corporate passport and send him to Hengsha.

Meet Malik at the Helipad
Self-explanatory.

Confront Sarif about the security leak
Jensen can also talk to Athene Margoulis about the issue beforehand.

Successfully persuading Sarif to relent his reasons for having the leak will reveal its purpose was to investigate Jensen's past. Jensen will receive the e-mails dug up by Radford.
