Dead Drops are short, encrypted audio recordings, found all over Empire City in Infamous and New Marais in Infamous 2. In inFamous: Second Son they are called Audio Logs, and are scattered across Seattle.
In Empire City, dead drops were attached to communication satellite dishes by the NSA agent John White as he investigated the terrorist organization known as the First Sons. While working for the Sons, John was ordered to set up a large number of unmonitored satellite dishes throughout the city, so he attached miniature audio drives to them to pass information along to his handlers. Unfortunately, due to John's disappearance following The Blast, the Dead Drops were never picked up by the NSA. Once Cole gains a decryption program for his all-purpose phone, he can travel the city and find all 32, hopefully learning something about his enemies along the way.
The Dead Drops provide a unique source for, among other things, the history of the First Sons, audio recordings of Kessler's experiments, the relationship between Kessler and Sasha, and last, but not least, the Ray Sphere.
Through the last Dead Drop, "A message for John White." Cole learns that John was ordered back to the NSA by Director Houston but he plaintively refused as he still hadn't recovered the Ray Sphere.
The drops don't play any part in the development of the story and Cole doesn't show any sign of retaining the information received by them. Some seem to have been just made, such as the drop about the Voice of Survival's death. This may suggest that John had to make them on a timed basis, and thus, didn't have classified information all the time.

Dead Drops make a return in InFamous 2. Here instead of simply having to find satellite dishes Cole will have to find pigeons that have encrypted Thumb Drives tied to collars on their necks and knock them out with Blasts or Bolts. Unlike the first game you cannot locate them using your sonar, and messages may differ depending on karmic state imported from the original inFamous. They were created by Sebastian Wolfe, former First Sons scientist, spy, and Conduit expert originally to inform NSA agents Lucy Kuo and John White on the First Sons' and later Joseph Bertrand's activities. Like in inFamous, the drops serve the same function. They do not progress the story but they give valuable background info on the Bertrand, the First Sons, and various other factions and characters.

inFamous: Second Son
Shortly after arriving in Seattle, Delsin Rowe was contacted via cell phone by a man named Tanner Black who claims to be in the Department of Unified Protection. He tells Delsin that his actions have started whispers in Washington D.C. about the need of the DUP and Brooke Augustine, and claims he'd like to help take it down from the inside. He sends a tracking program to Delsin's phone to help him find several audio logs that were scattered across the city, so Delsin can hear his story. Delsin then unlocks a series of side missions where he uses his phone to detect the distance away he is from one, and when he finds it, it lowers the DUP control over a District by 5%.

There are three trophies in inFAMOUS pertaining to finding the dead drops.
- Just Scratched the Surface- Collect all dead drops in the Neon District. (Bronze)
- Further Down the Rabbit Hole- Collect all dead drops in the Warren District. (Bronze)
- You're So Sly- Collect all dead drops in the Historic District. (Bronze)
There are two for inFAMOUS 2.
- Behind the Curtain- Collect 50% of the dead drops. (Bronze)
- Well inFORMED- Collect all dead drops in the game. (Silver)
There is only one for inFAMOUS: Second Son.
- Inside Track- Collect all the Informant Audio Logs. (Silver)
- The Trophy for finding all of the Dead Drops in the Historic District is called "You're So Sly" and is a reference to Sucker Punch's Sly Cooper series.
- The Dead Drops are most likely modeled after the Clue Bottles in the Sly Cooper series. In the Sly Cooper series, the clue bottles made a slight tinking sound when near them similar to the sonar sound the Dead Drops make when you are near them.
- It's okay to knock down the pigeons with Bolts, as you won't gain any Evil or Good Karma.
