This achievement is
- Story related and cannot be missed. -
In order to unlock this you simply have to start up the game and
play the prologue. You're chasing
Catwoman from roof to roof while learning the game-controls. Eventually you have to fight her. After you've evaded her attacks (with

) and beat her enough to reduce her health bar a cutscene appears and the achievement is yours!
Note: If you have played the
demo (which is the prologue) before that it'll create a save-file which will be used in the full-game and you won't be able to get it if you use it. So make sure to
start a new save-file and play the prologue again to unlock it properly.
