Catwoman will have her part in Batman: Arkham City expanded with the release of four DLC episodes, according to information from an official Gamestop strategy guide.

The feisty feline is reported to occupy around 10 per cent of the game time in Arkham City, so news of extra episodes will be great news to her many fans.

The guide also speaks of 12 side-missions in which "a number of major characters" will be revealed.

Batman: Arkham City will be released October 21.
