How Long to Beat Batman: Arkham Knight? Full Breakdown

Batman: Arkham Knight takes about 31 hours to beat if you focus on the main story, according to players on IGDB. With Gotham's side missions, plan on about 39 and a half hours, and around 58 hours to finish everything. The good news: 100% isn't just about collecting stuff, because it unlocks the game's true ending.

Main story: about 31 hours

Following the main plot, where Scarecrow unites Gotham's criminals to take down the Dark Knight with help from the mysterious Arkham Knight, takes about 31 hours. The pace is brisk, with lots of Batmobile sections, stealth encounters and the hand-to-hand combat that made the series famous.

With side content: about 39 and a half hours

Gotham is packed with side missions featuring famous Batman villains, grouped into the Most Wanted files. Doing a good chunk of them along the way brings you to about 39 and a half hours. That's often where the game is most fun, with shorter, more varied investigations and encounters.

100% completion: about 58 hours

To finish everything, you need to wrap up every side mission, including the many Riddler puzzles and trophies. Plan on about 58 hours. That's the price for the full ending, the one that truly closes out the Arkham series.

How many evenings is that?

At 2 hours a night, the story alone is about 15 to 16 evenings, roughly a month at four sessions a week. With side content, it's around 20 evenings, and about 29 for 100%. A reasonable length for a big open world.

Tips to go faster (or play smarter)

Upgrade the Batmobile's gadgets and armor early, it makes the tank battles much less of a chore. Don't do all the Riddler trophies in one go: grab them as you explore, since the grapnel and gliding save tons of time. And don't miss the big villain side missions, they're often the highlights. If you like tracking what's left, Lobbyd makes it easy to keep your progress in one place.

Verdict

Batman: Arkham Knight is mid-sized for an open world: long enough to really live in Gotham, short enough to finish in a month. If you enjoy completing everything, it's also one of the rare games where that effort truly pays off with the real ending.

FAQ

Do you need 100% to see Arkham Knight's true ending?

Yes. There's a standard ending once you finish the story, but the full ending requires completing every Most Wanted side mission, Riddler's included. That's why so many players push for 100% in this one rather than stopping at the credits.

Do you need to play the other Batman Arkham games first?

It's not required, and the story is easy to follow on its own. But Arkham Knight is the final chapter of the series, and several big moments hit harder if you know the characters and what happened in the earlier games.

How long do the Riddler trophies take?

They're the longest part of the side content, since trophies and riddles are scattered across the whole city and some need the Batmobile. Best advice: pick them up as you go rather than saving them all for the end.
