Batman: Arkham City won't be here until October 18, but that doesn't mean we can't appreciate more details, right?
Rocksteady provides fans with more info at the UK Arkham City site , and they talk about length, side quests, and more. First and foremost, game director Sefton Hill says the story mode is "designed to be story-driven while remaining open-world," so it's kind of a blend. Secondly, the main plot will take about 12-15 hours to complete but for the record, that's "less than half the game." Thirdly, he mentions the Arkham City Missions:
"These tell the story of what happens when Gotham’s most notorious super villains are locked up together. These run concurrently to the main story and can be tackled whenever you find them in the city streets. Some of my favourite moments are in these missions, including tracking down a deranged serial killer, solving a murder mystery, forming an alliance with a one-time villain and confronting the Riddler as he attempts to prove once and for all he is better than Batman."
Sounds awesome. Then there are riddles to solve and secrets to locate, which should be like catnip for all the adventuring completionist types. See, the Riddler has "definitely raised his game" this time around, so it's not just about finding the secrets; nearly every "riddle" requires that you "use your gadgets in inventive and interesting ways." So what does all this mean?
Well, it means what he said above- if you want to rush right through, the length is 12-15 hours. If you actually want to do everything the game has to offer, it's more like 25-30 hours.
