It's surreal, the number of long-in-development games that might actually burst forth into the light of commercial release in 2011. In the time since Rockstar Games and Team Bondi's Los Angeles crime saga, L.A. Noire, initially appeared by way of scant few screenshots and little concrete info back in the mid-2000s, children have been born, learned to crawl, walk, talk, and use basic arithmetic. And yet, while some games of similarly protracted and clandestine development cycles perhaps look worse for all that developmental wear, L.A. Noire seems to have benefited from its extended gestation. Though the game was only shown via a developer-driven, 30-minute demo at PAX East 2011, what Rockstar showed certainly made an impression.

At first blush, L.A. Noire seems to have all the hallmarks of a typical Rockstar joint, namely a third-person protagonist wandering around an open world full of sex, murder, corruption, and everything illicit in between. In this case, the setting is 1947 Los Angeles, and you play as Cole Phelps, a young officer in the LAPD rising through the ranks of the department. Phelps, played by Mad Men's Aaron Staton, starts out the game as a beat cop, working the streets and securing crime scenes for the detectives above his pay grade. However, over the course of the game your career will flourish, with stops in a variety of different units, including traffic, arson, vice and homicide.

 Investigation is the name of the game. Also the name of the game: L.A. Noire. The mission shown in the PAX East demo was one of the earliest homicide missions, titled "The Red Lipstick Murder." Rockstar was quick to point out that many of the game's cases are rooted in true crime origins, drawing inspiration from real scandals and murders of the period. Similarly, each case is a stand-alone story event with a self-contained narrative. The game will include an overarching plot revolving around Phelps, as well as his troubled past--some of which involves his service during World War II--but nothing shown in the PAX demo alluded to the direction any of that story might go.

Instead, we were introduced to intense, brutal violence right from the get-go. A woman is dragged screaming from a car at a popular heavy-petting spot overlooking the city, and is subsequently beaten to death with a tire iron. The faceless killer fades into the dark, and we are introduced to Cole. Upon arriving at the scene with his cantankerous, half-drunk new partner, Rusty Galloway, Phelps goes right to work, bee-lining for the stark-naked and desecrated corpse. Side note: If you are sensitive to seeing fully naked dead ladies, this is probably not the game for you.

After a bit of rat-a-tat back-and-forth with some nosy reporters, Phelps begins investigating. Rockstar emphasized the nature of the game's investigation mechanics, compared with other crime-solving adventure titles. Rather than just poking around until you find the right highlighted object that progresses you to the next section of the story, L.A. Noire is aimed at getting you to use your head and actual investigation. For example, when you examine the woman's body, you can highlight several sections, including her head, her arms, her torso, and so on. While highlighted on those sections, you can use the controller's analog sticks to turn them to look more closely at wounds, markings or other possible evidence. Elsewhere, it pays to be dutiful in your searching. Supposedly, you will never quite know when an object might pertinent to your investigation or not, so it pays to be painstaking when it comes to searching and evidence collection. All of your evidence and information is kept inside your notebook, which keeps a detailed and easily accessible list of everything you've discovered so far.

 The game is thick with era-specific atmosphere. This careful style of play carries over into interrogations. As persons of interest appear, you will find yourself asking them pointed questions about the victims, what they saw, and possible involvement in the crimes. With each response given, it's on you to determine if the person in front of you is being truthful or not. How you determine that comes largely from intuition. If a person is being direct, making eye contact, and saying things that don't contradict evidence you have, they're almost certainly telling the truth, which means you should select the "truth" option when directing your next question. However, if someone is being evasive or stumbling over their words, they're likely lying. If you have evidence that directly contradicts what they're saying, you can choose the "lie" option, and directly confront them. If you currently lack that evidence, choose "doubt," and you'll press them without out-and-out calling them a liar.

It's easy to envision a mechanic like this boiling down to a series of painfully obvious visual cues and character tics--after all, subtlety in facial expression is not something games have really done well up to this point. Enter a new form of facial capture technology, which Team Bondi has used to capture the expressions of the actors as they deliver their lines in the recording studio. The aim of this tech is to finally cross over that seemingly insurmountable valley of the uncanny and create video game characters that blink, smirk, furrow, and frown with naturalistic quality. If the demo I saw was any indication, they've nailed it.
