For Sleeping Dogs’ combat, United Front Games consulted with mixed martial artist, Georges St-Pierre.

“We took 35,000 to 40,000 reference photos and hour upon hour of video footage,” says executive producer, Stephen van der Mescht.

Sleeping Dogs still has a few cuts for Japan like an event scene where a person’s organs are exposed was modified. Another scene with a sexual reference was cleaned up with alternate camerawork.

Oh, and there’s a little homage to Bruce Lee in the game as well.

A Sleeping Dogs trailer shows off the game’s combat system using both regular moves and takedowns using objects in the environment.

Goldtooth Creative give a behind-the-scenes look at the creation of the trailer that was used to announce Sleeping Dogs, Square’s triad infiltration game set in Hong Kong.

“Both the police and Triad were incredibly valuable sources of information for us. One of the interesting things about the Triad is a lot of their operations are not that sinister.”

“You have a mix of very dense urban environments, which have a different flavor to Hong Kong’s night markets and fish markets areas that feel different from the skyscrapers of Central.”

From Bully to Sleeping Dogs, the story behind United Front Games’ multidirectional combat system and the more details about the game’s shooting sequences straight from the development team.

Square Enix have announced U.S. and U.K. release dates for Sleeping Dogs, along with pre-order details.

That’s one way to hijack a car in Sleeping Dogs.

Sleeping Dogs is set in Hong Kong, but the game won’t ship with a Cantopop soundtrack. Square Enix licensed music from heavy metal band DevilDriver for the action game.

I think Sleeping Dogs was inspired by another Square Enix Europe title – Batman: Arkham Asylum since the hand to hand combat system is pretty familiar. Players use a button to attack and another button to counter right before an enemy hits you.

United Front Games discuss their research trips to Hong Kong, which they used to as a basis for creating the city in Sleeping Dogs.

Square Enix and United Front Games put out a new trailer for Sleeping Dogs this morning, showing off what the game looks like now.

Square finally released in-game screenshots that show off a bunch of different scenes.
