A series of automated beeps emit from the dormant Exo frame. On a nearby screen, a small prompt appears:

//REMOTE DOWNLOAD INITIATED

A data uplink notification flashes in Ghost's eye. It's a message:

"Hello, mate. Our paths cross again. I've liberated some high-priority BrayTech data from House Salvation—data pertaining to Revision Zero—and well, it appears I've tumbled into a spot of trouble.

The Fallen caught wind of my expedition and are hunting for the data I stole. I'm trying to lure them away, give a tail for them to chase, but the Hidden need you to recover the data from the dead drops I stashed them in.

First thing's first, you'll need to retrieve an index cipher to help unlock the dead drops. I will provide more details as they are needed.

—FEN-092"
