Alongside the main campaign mode Batman: Arkham City features number of playable missions as Catwoman, which can be activated using the special voucher code found inside your copy of the game. Catwoman is an extremely different kind of character to Batman, so you'll need to take a little time to get to grips with her whip, speed and vicious claw attacks.
With a huge number of side missions to explore, you'll soon find yourself rescuing political prisoners from thugs in the street, hunting down the hundreds of Riddler challenges and answering payphones to take on smaller, but equally rewarding missions involving the psychotic Victor Zsasz. You'll also find yourself bumping into familiar faces from the Batman universe during these quests including Arkham Asylum's monstrous Bane and the cold blooded assassin, Deadshot.
The hugely addictive Challenge Maps that Batman: Arkham Asylum so much fun to play make a welcome return, pitting you against dozens of enemies in various situations that require you to use all of the skills you've accumulated throughout the course of the campaign mode. While they do start out quite easy, the Challenge Maps become increasingly harder the further you progress, so make sure you have upgraded as much as you can before taking them on.
