You can get this trophy in chapter 2. There are 4 zip lines in total that you need to slide across. 3 of the 4 ziplines must be crossed over as part of the story, meaning there is only one zipline that you need to find. The lightbulbs on the ziplines make them easy to locate. After crossing the first one at the start of the chapter the remaining 3 are on the rooftops during the chase scene. The video below will show you the locations of them all, but if you look out for the lights, its hard to miss them.
Use all the zip-lines to traverse the city
