Batman, who had come out of the shadow of witnessing his parents being killed, is no longer the rebellious and lonely hero after growing up. With the help of police officer Jim Gordon and prosecutor Harvey Dent, Batman continues to travel around the world without worries, fighting an endless battle against the growing threat of crime. Gotham City, where he lives, is also the place where the progress is most obvious. The crime rate continues to decline at an alarming rate. After all, the other party is the Batman who can go to heaven and earth. Who dares to act without two courage? However, in a city like Gotham where technology and filth coexist, peace cannot be maintained for too long. As expected, a new round of chaos soon swept the entire city, and people were once again shrouded in panic. The one who claimed to be willing to take responsibility for all this was naturally the source and ruler of all the chaos-the Joker. Regardless of the ultimate purpose of the Joker's crime spree, his intentions are all evil, and his actions have long endangered the normal lives of Gotham citizens... including several very important people around Batman, and what he needs to do is to crush this new crisis with his own hands. However, when facing this most targeted and vicious opponent in history, Batman has to move every high-tech weapon that can be used from his underground armory, and he has to constantly struggle to find answers for everything he once believed in.
