After flooring Man-Bat briefly for the first time, you’ll have a brief chat with your support staff on the communicator. You’ll be informed of the identity of the Man-Bat and the location of a lab where he had been conducting experiments.
Head over to the new objective marker on the map, located in Chinatown on Bleake Island. Enter the doorway indicated and take the elevator down.
You’ll find the laboratory through the door at the end of the hallway and as you enter a video will play on the screen to give you a bit of background into what is happening story wise with this Most Wanted mission.
To continue, you’ll need to interact with the computer on the desk against the wall just to the left of the entry door. This will kick off a mini-game that we’ll need to successfully complete to progress further.
The mini-game takes place on the computer and involves a pair of DNA helix strands rotating. Below each of these is a small symbol, either ‘X’ or ‘O’. We want both strands to have the ‘O’ symbol active at the same time so that we can synthesize an antidote. Unfortunately, they will flip over to ‘X’ regularly and you’ll need to flip the rotation of the associated DNA helix to revert it to ‘O’. Each of the DNA strands is controlled by one of the thumb sticks, so make sure you switch them over as soon as ‘X’ appears or your time to completion will increase.
Backtrack through the lab and exit back onto Bleake Island.
