Batman: Return to Arkham, the two-pack that features current-gen versions of Batman Arkham Asylum and Batman Arkham City, won’t make its previously announced July 26 release date.

Harley Quinn doesn't get naked and have sex in any of the Batman video games that she's appeared in. But the Joker's psycho girlfriend does exactly that in the new animated movie tied to Arkham Asylum and Arkham Origins. It's not the only surprise in there either.

The fact that you’d be able to play as Deathstroke in the upcoming Batman game squeaked out a few months ago, but this trailer is the first look we’re getting of Slade Wilson in action. Bad-ass, no?

The folks making Batman: Arkham Origins know exactly what they're trying to accomplish with this year's Dark Knight video game. It's the story of the night where Gotham City's supervillain culture spins irrevocably out of control. This is when the Dark Knight becomes a legend, they say. So, it's really too bad that…

How do real psychiatric hospitals approach the so-called "criminally insane?" Who are these mentally ill criminals? And importantly, what does mental illness have to do with violence?

Having previously worked for companies like NCSoft, artist Kan Muftic's last major piece of gaming work was being one of those helping define Rocksteady's take on the Batman universe in the two excellent Arkham games.

Slipped within Time Warner's call to investors last week was this mention, from the company's chief financial officer, that the next entry in the acclaimed Arkham series of Batman video games will be arriving in 2013.

Part of what's made Rocksteady's two Batman video games such great experiences has been the pitch-perfect stories players encountered in each. The narrative contributions in both Arkham Asylum and Arkham City came Paul Dini, who's written excellent Batman stories for TV and film as well. But it seems that Dini may…

Warning, spoilers ahead, starting with the end of Casablanca:

There were normal action figures based on Batman: Arkham Asylum. They came out a while ago, and they were fine. These premium figures, though, are brand new.

Enterprising hackers, who have cracked open the PS3's v3.55 firmware, now have a pretty neat feature running on Sony's new handheld: the ability to remotely play games like Battlefield 3 on a PlayStation Vita.

While games like L.A. Noire and Batman: Arkham Asylum put on a good detective show, are we really detecting anything? Commenter Soleyu describes what a true detective game should be like in today's elementary edition of Speak Up on Kotaku.

On the eve of the release of Batman: Arkham City (which the Kotaku staff gave a unanimous "yes" in last week's gut check), I thought it would be fun to take a look back at the various Batman themes we've had over the years, and see how the motifs and melodies that summon the caped crusader have changed over time.

Yesterday, I gave you a brief tour of some of the new Batman: Arkham City and Arkham Asylum toys I spotted at New York Comic-Con on Thursday.

Batman: Arkham City may be about to hit shelves, but two of these new figures are for the last great Batman game: Arkham Asylum.

We're on the cusp of enjoying the next great Batman game, but if you're a big, big fan of the last one, Batman: Arkham Asylum, Square Enix has some mighty fine action figures you might be interested in.

Thanks for ruining that, IGN.

Of all the things that Batman: Arkham Asylum had going for it—and there were a lot of them—my favorite thing was the Riddler challenges.
