The Joker, Poison Ivy, Scarecrow, The Riddler, Killer Croc, Bane, and Mutated Henchman OH MY!!!
So let me go through this game. The gameplay is great everything is blended in so nicely, and it runs really smooth. They also have made the fighting in this game something to remember basically X is the attack button while you use Y to counter, B for cape stun, A to jump/evade. You can string your attacks all in one with the effortless combo system, making it possible to fight like 20 guys and a monster at once as you will find out. The graphics are unbelievable! Everything in Arkham has been carefully detailed to make the most realistic environment you can imagine! The voice acting in this came is so cool with Mark Hamil (Luke Skywalker) as the Joker and boy does he do a great job, as a matter of fact everyone does a good job all the way down to the henchman to the laughing teeth.
Another cool thing they added was the Riddlers challenges which you want to find to unlock the challenge maps, character bios, trophys, etc. You will have to have a keen mind and use Batmans very cool Detective mode to solve some of the Riddlers well, riddles. He's also hidden around trophy's for you to find, patient interviews, and there are Arkham Asylum statue things to find that unlock the history of Arkham.
The challenge maps give this game some very good replayability, as they range from easy to very hard and even after you beat them you still want to beat your score. There are fighting challenges, to Batman in a room taking out the armed henchman with goals you need complete to get the medals.
So to sum it up, as I could go on for hours and hours saying how good this game is I'll say this. It's such a good game I can't stress that enough, I don't know how people wouldn't like this game. Even gamers who don't like Batman will appreciate how well this game was made and how much time they put into making it a game for people to remember!
