Discworld Noir is the third DiscworldAdventure Game. It was made by GT Interactive and released in 1999.The game follows Lewton, the Disc's first and only Private Investigator. The game starts as Lewton is given a simple case to find a man. Since this is an Adventure Game set on the Discworld and acted out through a Film Noir genre filter, it soon becomes clear that there is far more going on.While the game in many places is an Affectionate Parody of Film Noir, it also plays many of the tropes straight, even if they are given a unique Discworld spin.
Conspiracy Theorist: Malaclypse, a servitor of Errata, Goddess of Confusion and Misunderstanding. This is a Shout-Out to out world Malaclypse the Younger (a penname for Gregory Hill), the supposed creator of Principia Discordia, which details the worship of Eris, the Goddess of Chaos.
A reasonable chunk of his gibberish is actually true, and covers a lot of Discworld (and Discordian) mythology/history.
Continuity Nod: Lewton mentions that the Elucidated Brethren of the Ebon Night has been "forcibly disbanded."
One stained-glass window at the Temple of Small Gods represents an angel presenting a pizza (with a small bay leaf) to a prophet, a reference to a religion mentioned in Mort that believed that the Discworld was created in the image of a pizza.
Cursed with Awesome: Discussed. Lewton isn't very happy about becoming a werewolf, but Carlotta (who infected him) says it's a great gift. It does turn out to be pretty useful.
Darker and Edgier: The entire game feels like a dark Watch book, to fit with the Noir theme. It is also quite darker than the two previous Discworld games, both in feel and in colour palette. Actually works.
The Dog Was the Mastermind: Well more accurately the bestial serial killer is the god Anu Anu who spends most of his time in the form of a small dog. However it is his worshippers who choose his victims and they are all in turn being manipulated by the real mastermind.
Expy: Many of the characters in the game are quite clearly Discworld versions of characters from Casablanca and The Maltese Falcon. "Tomb evacuator" Laredo Cronk is an obvious Lara Croft reference, and the Indiana Jones theme occasionally almost plays in the background of the archaeologist's guild.
Film Noir: a bitter, cynical, life-weary, alcoholic detective narrates his crime investigation in a dark, corrupt city. Almost no one is telling the truth or can be trusted, and adultery, blackmail, murder and conspiracy are the least despicable things perpetrated. And it's always night and it's always raining.
Gods Need Prayer Badly: As usual on the Disc. The entire plan turns out to be an attempt by the worshippers of the small god Anu-Anu to have their god defeat Nylonathotep and thus win enough believers to become a recognised deity.
Half-Human Hybrid: The bartender Mankin is half-elf, in the Discworld setting, that makes him very unpopular (since Elves are cruel and vain beings from a parallel dimension), and gives him no special powers. He is a very bitter person.
Lewton: A lot of strange things had happened to me since becoming a private investigator, but the weirdest was the irrepressible sensation that the most important thing for me to own as a P.I. was a door, with my name painted on the glass. Some mysteries are best left unsolved, I guess.
How We Got Here: The game opens with a cinematic in which the protagonist is chased down and stabbed to death. You spend the first half of the game looking for the McGuffin whose possession will result in your untimely demise.
In Medias Res: The game opens with Lewton buried, having been fatally stabbed in a cinematic. The first half of the game is his story of how he got into this situation, the second is how he deals with its aftermath.
Large Ham: In-game actor Privetier is a huge ham, much to Lewton's displeasure.
Only Smart People May Pass: It looks like the game is headed for this when an ancient guardian wants to ask you a riddle to see if you are worthy to receive the McGuffin. Then come the subversions, first by the guardian who happened to forget the riddle during his 400-year-wait (but still insists to only hand the item to those who answer it) and then by Lewton who points out that someone of the unworthy faction would just hack the weaponless guardian to pieces. As he's in somewhat of a hurry, he gives the guardian the option to hand over the McGuffin - or he'll just pretend to be unworthy enough...
The guardian relents.
Out of Character: Insofar as characters who appear in the books are hanging about, they're reasonably true to the books-except for Vimes. Vimes holds a massive grudge against Lewton because the particular indiscretion for which Lewton was fired (accepting a bribe) ranks just short of murder in Vimes' book (which is true to the books), and he's only too willing to accept that being found unconscious at the crime scene is proof of guilt. This in contrast with his portrayal in the books where he hates "clues" (like, say, being found unconscious at the crime scene) because they often create fantastic stories out of the theories but do little to solve the case. In the books his first duty is to justice, and if that means letting the guy he doesn't like walk so that the real culprit ends up behind bars, he doesn't want it any other way.
Essentially, Vimes has been handed the role of Sam Spade's nemesis Lt. Dundy even though it's not a great fit, because it's still much closer than giving it to, say, Carrot.
Could be Fridge Brilliance at work: Vimes may actually know that Lewton isn't a likely suspect, but wants Lewton to clean up this mess to make amends for his past failure as a copper. Leaning on Lewton may be Vimes playing out the same hard-ass role he adopted in Night Watch for his "ginger beer trick".
Parody Name: Mundy for Thursby; Jasper Horst for Casper Gutman; "Mount" Malachite for "Moose" Malloy; Nylonathotep the Laddering Horror for Nyarlathotep the Crawling Chaos.
Posthumous Narration: Lewton gets killed in the opening cinematic, and and a good chunk of the game is a flashback.
Lewton: I've had some bad days since I started work as a private investigator. But I've never woken up dead before.
Private Eye Monologue: Played straight and parodied, with the usual Discworld insistence that metaphors have to be precise. Also, Lewton is a very, very bitter man.
Red Herring: Unusually for an adventure game, there are a few false leads, such as the story of the madman Azile, who buried people upside-down, and Malaclypse's gibberish. Mostly.
Shout-Out: The game has innumerable shoutouts to Casablanca, and popular culture in general. There are also two framed pictures showing landscapes from the previous, more colorful, Discworld games.
