A new addition in this sequel, power lines not only run across from building to building, vertical power lines (or launch poles) can now be found on the side of buildings throughout New Marais. As with the power lines, these will also have the glowing yellow bulbs attached to them. To use one, simply jump up to them and you’ll automatically use it and launch into the air. Launch poles can also be found on metal towers in the train yards and power plants in the second island.
Simply use these vertical launch poles 50 times, and the trophy will unlock. Note that this can be done on the same pole if you wish to do so; it doesn’t have to be 50 different poles. You’ll most likely get this by playing through the game naturally anyways, so there’s no real need to grind it.
