From PCGamesN: “One of the weapons you can stumble upon during your parkour adventures in Dying Light 2 might look familiar if youve played Cyberpunk 2077. If you play your cards right, you can get a pair of special knuckle dusters called the Cyberhands 2177 that look like the cyberpunk games Mantis Blades.
To get them, youll want to take an elevator to the top of the VNC Tower once youve completed the Broadcast story mission. Once you exit the elevator on the roof, youll want to turn left and scale the green metal structure for a better view. You should notice two mossy skyscrapers that are smaller than the VNC Tower. Use your glider to reach the closer of the two, and then glide to the next one.”
