A simple equation later and Arkham City is looking to be over 60 hours long, sadly this is NOT the case; we reached out to Rocksteady for confirmation, and we've got the definite answer!
To complete the main storyline of Arkham City, players can expect to spend 25 hours as the Dark Knight. This figure does not include side missions.
To complete the entire game 100%, it is expected that the experience will last for over 40 hours. This figure does not include Challenge Maps.
We'd like to thank Rocksteady's Sarah Wellock for confirming the information.
For the sake of comparison, Rocksteady estimated it would take players 12-15 hours to 100% complete Arkham Asylum.
How do you feel about Arkham City's length? Is it longer or shorter than you thought? Let us know!
BOWDEL. Si seulement c'était vrai...40h pour se faire juste la campagne complète de Arkham City, sans les défis. Les développeurs, ces mythos.
