How to unlock the Serial Killer achievement in Batman Arkham City - Definitive Guide
Basically shows you all the locations leading up to finding the serial killer.
Side mission – Identity Theft.
You’ll be able to start this side mission later on during the story. After you’ve located the first victim (outside the Arkham City Processing Center). Scan the body until the crime scene is at 100% complete. You will then have to track down the witness who saw the attack.
From here there are 2 more victims for you to locate.
- The second one can be found in an alley just to the left of the Church.
- The third one can be found in an alley just outside the Restricted Area near the Ace Chemicals Building.
Once they have all been scanned, you will be tasked in to tracing some evidence which will lead you to a thug who reveals the hideout location (to which is added on your map). Head to the location, play the tape () to which Hush will make an appearance. Once the talking has finished, open the gate after which you will gain this trophy.
For a visual location of the victims, you can refer to the following map below:
This side-quest (Identity Thief) is quite a bit harder to trigger. You need to basically be standing on top of the body for the game to register you've found it. Again, follow the numbers on the map below to proceed through the questline. If you are having trouble triggering the other locations try again later once you get further in the story or reload the city by entering and leaving a building or quitting to the menu and starting the game up again.

This side-quest (Shot in the Dark) should trigger early in the game as you pass the location marked "1" on the map below. Once you finish that, the next portion begins at "4" and you will follow along as such. If you are having trouble triggering the other locations, try again later once you get further in the story or reload the city by entering and leaving a building or quitting to the menu and starting the game up again.
