Voices from the Dark

Voices from the Dark is a side quest in Deus Ex: Human Revolution.

Meet Zeke Sanders
During the Neutralize the Terrorist Leader mission, if Zeke Sanders escaped, after being convinced that he was manipulated by the hacker, he will leave a message to meet him in an alley off Bagley Avenue, near the Sarif Building.

He will give Jensen a pocket secretary with access codes and some miscellaneous information regarding the FEMA complex.

Note
If the Highland Park mission is started before meeting Zeke, this side mission is lost.
