Batman: Arkham City is the sequel to Batman: Arkham Asylum.
The game begins a while after Batman: Arkham Asylum. Arkham City is a big section of Gotham City which has been turned into a large-scale prison for its criminals, all constructed by Hugo Strange. Very early in the game Bruce Wayne is campaigning to demolish the institution when he himself is incarcerated under Strange's orders.
While Strange prepares to commence "Protocol 10", Wayne obtains his equipment via airdrop from Alfred, allowing him to become Batman. Now it is up to him to find out what Protocol 10 is. Along the way he fights several famous villains, among them Joker, Riddler, Penguin and Two-Face.
The story is pretty well done. Many recognizable characters on both sides of the Batman mythos are along for the ride.
Batman: Arkham City plays and controls much like Arkham Asylum. But one thing you will notice is that the game takes place in an open city, rather than in a single area. Arkham Asylum was by no means a small game, but in Arkham City the player is able to get the full Batman experience by gliding around the city in a much larger scale.
The combat system is pretty much the same as in previous game. You punch, counter, and use gadgets and finishing moves to subdue large amounts of enemies.
Besides of the main story and side quests you also have a lot of other stuff to do like solving Riddler secrets, Catwoman Missions, challenge maps and more. This game will last you a long time if you are trying to go for 100% completion.
The graphics are stunning and all the characters look really good. Faces and facial expressions are brilliantly made.
The soundtrack is literally Hollywood movie quality. The voice acting is incredible and everything else sounds great as well.
Batman: Arkham City is a great experience for anyone who likes Batman or who wants to discover his universe. It is definitely worth to buy and to play.
