Great sequel to Arkham Asylum! Rocksteady have outdone themselves. They not only preserved everything that was good about the first part, but also expanded it all. The plot took on a different scale, because a huge number of new characters were added, while the old ones were not forgotten. In terms of gameplay, the most significant expansions are the open-to-exploration area of Arkham City and the ability to play as Catwoman! The gameplay for her is very different from the dark knight, because it is built on acrobatics and several special features available only to her. The free world cannot be called alive, but it shouldn’t be, because Arkham City is a gloomy place inhabited mainly by criminals. However, it can be studied, and this is good news. You can find a bunch of references and Easter eggs to the original comics, you can solve Ridler's riddles, which, by the way, are made separately for Batman and separately for Catwoman. Or you might stumble upon some mini-plot in which you can meet some other character from the universe! Anyone who liked the first part, and not only, should definitely take it!
