This side-mission will be unlocked whilst gliding around on the rooftops sometime after reaching Miagani Island for the first time. Essentially, you’ll be treated to a short jump-scare scene with Man-Bat whilst exploring that will trigger the start of the Most Wanted mission. Once you have encountered Man-Bat for the first time, a Most Wanted icon will appear.
Once the side-quest has commenced, the first thing that we are going to want to do is find Man-Bat. He can be found flying around the skies of Miagani Island, close to the first objective marker. The easiest way to spot him is to get onto the rooftops or glide around above the city with Detective Mode activated during which he’ll appear as a flying red skeleton that shouldn’t be hard to see.
After locating Man-Bat we need to tackle him in mid-air. This requires us to scale the buildings here, activate a glide and time your fall/movements so that you make contact with him on the way down. Doing so will trigger a brief cut-scene.
Following our first brush with Man-Bat, our objectives will be updated.
