It will be left up to Nightwing to use swiftness and stealth to infiltrate the police department and put an end to the menace. Some points of interest to make note of is that Nightwing will be able to use familiar gadgets from the original story and the entire mission will take place during the day in Gotham City.The Insider episode also sheds light on new tracks players will be able to blast through.
