You will play as her a total of 4 times as part of the story, with the fourth time happening after you finish the final boss as Batman.



It's all part of the story, so you'll just swap to her when it's time to do so.



After you've finished the story line, then there will be sections of the city where you can swap back and forth between Catwoman and Batman at will. Some of the Catwoman Riddler trophies cannot be reached until you have free reign of the city as Catwoman.When can i play as catwoman in batman: arkham city?

The four story segments for Catwoman are:





(SPOILERS)






First time: Prologue breaking in to Two-Face's headquarters and stealing a flash drive

Second time: Right after Harley Quinn knocks Batman out, Catwoman gathers her equipment from her apartment and breaks in to see Poison Ivy

Third Time: After Joker steals the cure and you fight him in the fun-house, Catwoman breaks in to Hugo Strange's vault and steals two cases with unknown and unseen contents. Probably a reference to "Pulp Fiction"

Final time: Epilogue, Catwoman's apartment is blown up and she goes to confront Two-Face on the whereabouts of her goods.

After Two-Face is knocked out Arkham City is open for exploration and finishing any side missions and there are places where Catwoman and Batman switch out
