The highly-anticipated Batman: Arkham City is set for release on October 18. Check out this awesome concept art for the game's villains by Carlos D'Anda, illustrator of the recent Arkham City comic miniseries.

I've already given yo a look at the super-sweet Batman variant skins offered as incentives for Batman: Arkham City pre-orders (most of which, frustratingly, are not available in the U.S. at the time of this writing). 

And, as previously reported, here in the States, Best Buy is offering Robin's Challenge Maps - featuring Robin as a playable character - for their Arkham City pre-orders. Turns out Tim gets some skins of his own, as part of the package. There's the badass Arkham City original, as previously seen, plus a Red Robin variant, and my personal favorite, old school Bruce Timm-style Robin as seen in Batman: The Animated Series.

Well the upcoming Batman: Arkham City just keeps looking better and better, as more and more of Batman's greatest rogues are revealed. In this latest trailer released by Rocksteady and Warner Bros., a new challenger emerges: Mr. Freeze!

Another skin has been added to the already awesome list of Batman: Arkham City exclusives. This latest from arkhamcity.co.uk:

It appears that French retailer FNAC is offering a pre-order incentive of their own for Batman: Arkham City. A Batman: Year One skin!

That makes six variant skins to date, with some time left between now and Arkham City's release date of October 18. Any guesses as to whether we'll see some more? And which incarnations of the Dark Knight we'll see? I'm holding out hope for Vampire Batman myself - or crazy Knightfall Azrael Batman! How about you, what's on your wish-list?

Over the weekend I gave you a peek the Batman: Arkham City Batman Beyond skin, included with pre-orders from GameStop UK, as well as the super-sweet Bronze Age '70s Batman skin, a pre-order bonus from UK e-tailer ShopTo.net.

So this is America's punishment for fleeing religious persecution and establishing our little colonies.

Well, this and a crushing sense of irony, but lets focus on superheroes and videogames for now.

GameStop UK is offering this Batman Beyond skin for customers who pre-order Batman: Arkham City for XBox 360 or PlayStation 3.

In other 'The British have it all over us' Arkham City news, The UK's Shopto.net is offering this awesome '70s Batman.

It's not enough that they have Emma Watson, Paul Weller, a government that's finally cracking down on evil journalists, and super-sweet Cthulhu hats? Now the British get superior Batman: Arkham City skins? Where's the love for 'Murica?

Never trust a psychiatrist with a sinister movie-villain accent. That's the lesson of this phone conversation I've obtained, featuring the mayor of an unnamed city speaking with a particularly strange doctor. This might or might not tie into a certain game set for release in October. (Spoiler alert: it does.)

Rocksteady and Warners have released a new trailer for the upcoming Batman: Arkham City, featuring a first look at the surprisngly Cockney-accented Penguin. Oh, and he has a little surprise for Batman.

It will be a surprise to you, too, as this old-school DC villain has never been mentioned as playing a role in Arkham City until now. Little hint: "Born on a Monday..."

Courtesy of London's Metro, here's a look at Two-Face from the upcoming Batman: Arkham City. He's one of many new baddies you'll face in the city that doubles as an institution for the criminally insane - and can we just take a second to appreciate what an awesome concept for a game that is?

Batman: Arkham City will be released in the US on October 18, and in Europe on October 21
