Discworld Noir

Originally released for Microsoft Windows, it was later released for PlayStation by Teeny Weeny Games, the resurrected form of the already insolvent Perfect Entertainment. Pratchett consulted on the story and provided some of the dialogue, being credited for causing "far too much interference."

Discworld Noir is an adventure game, in which players take control of the character of Lewton, visiting various locations in the city of Ankh-Morpork, finding items to help solve puzzles, and conversing with a wide variety of characters. the game's story is divided into a set of acts, in which the player must complete various tasks to advance the story. Much of the conversations in Discworld Noir focus on a more structured manner than in previous Discworld games. Alongside a greeting function, the player can converse with characters about simple conversation topics, as well as show them items collected during the game, and question them on leads noted down in Lewton's notebook; once a lead is of no further use, its scratched out and unselectable. The game uses a "threaded" structure, in which there are separate "vignettes" that the player may come to at different points. For example, missing a clue early on in the game will cause a character to give it to the player later in the game. In addition to traditional adventure mechanics, the player will later gain the ability for Lewton to transform between a human and a werewolf, allowing them to collect scents to help solve additional puzzles. Like the previous Discworld games, the PlayStation version of the game supports the PlayStation Mouse.

Discworld Noir contrasts deeply to the first two games set in the Discworld universe, adopting a "grittier, darker and more realistic" style in its story, while featuring an original story by Terry Pratchett not derived from any of his novels in the Discworld series. Like with Pratchett's work, the story parodies a mixture of traditional hardboiled fiction and film noir, as well as a combination of dark fantasy and Lovecraftian horror. The film noir elements feature significant references to the 1942 film Casablanca, as well as a heavy use of "discordant" strings and dissonance in its background music, matching to the style of jazz and blues pieces from the early 20th century; multiple references towards the horror elements are made of the works of H. P. Lovecraft. The game's lead protagonist that players control is Lewton, a former member of the Ankh-Morpork City Watch, who left to become the Discworld's first and only private investigator within the city of Ankh-Morpork. The character is based on the classic private detective figure, with an appearance and jacket reminiscent of noir detectives; PC Zone compared him to Sam Spade and Philip Marlowe. Other new characters to the Discworld universe include: Carlotta Von Uberwald, a femme fatale figure, and one of the primary antagonists; the troll criminal Horst; Ilsa Verbay, a former love interest of Lewton; and Two-Conkers, an Agatean Empire citizen specialized in archeology. The game features some notable characters from the Discworld series, including Commander Vimes, Corporal Nobby, and Death. While the story is an original piece by Pratchett, the writer viewed it like his previous games as in a "parallel Discworld" to that of the novels. Despite this, the game's designer Chris Bateman devised Noir's events to fit in between the stories Feet of Clay and Jingo.

Lewton, a former member of the Ankh-Morpork City Watch, seeks out work after becoming the Discworld's first (and only) private investigator. He is hired by the mysterious Carlotta Von Uberwald to track down a man named Mundy. The only detail he receives is that Mundy was away in the nation of Tsort, and that he disappeared shortly after he returned to Ankh-Morpork two days ago previously. Accepting the case, Lewton's search leads him to encounter the troll Malachite, who requests his help in tracking down a troll named Therma, and the father of Carlotta's deceased husband, Count Von Uberwald, who hires him to track down his missing dwarven driver, Regin. While Regin turns up dead in the river Ankh after being murdered while driving fast in Count Von Uberwald's carriage, the other two cases of Lewton's see him knocked out as he closes in on his objectives: Mundy is murdered after he finds him; while Malachite is murdered when the PI takes him to an arranged meeting with Therma. Lewton's former superior, Commander Vimes, strongly suspects him of the murders, but does not agree to his belief they are linked to a spate of recent, ritualistic murders, dubbed the Counterweight Killings, that the Watch are investigating. At the same time, Lewton learns a troll named Horst, an underworld criminal, is after a relic known as the "Golden Sword", which Mundy was supposed to give to him, and which Carlotta is seeking to acquire herself. Finding Horst believes he has it, and tailed by Horst's associate Al-Khali, a shady dwarf, Lewton finds Mundy hid the relic in a crate that went to the Guild of Archaeologists. Needing help to access it in the Guild's vaults, Lewton turns to help from Ilsa Verbay, a former lover of his who recently returned to Ankh-Morpork with her husband Two-Conkers, an archaeologist from the Agatean Empire. With her help, Lewton recovers the relic, but is hounded by an unknown pursuer when he leaves the Guild. Accidentally dropping the sword in his efforts to escape, Lewton is stabbed in the chest and presumed dead by the Watch. A few days after being buried, Lewton re-emerges alive, but discovers from a talking dog named Gaspode that he has become a werewolf. Discovering his newfound abilities can be useful, Lewton decides to investigate the Counterweight Killings. His research on the relic leads him to a priest of the goddess Errata, who reveals that the Golden Sword is actually known as the Tsortese Falchion – an ancient blade forged for Errata, which was lost following a major war in Tsort many years ago. Lewton also learns the relic is incomplete – it is missing a jewel that empowers it, and which is believed to be hidden in Ankh-Morpork. Meanwhile, the investigation into the killings reveals they are part of a ritual to summon Nylonathatep, a being from the Dungeon Dimensions. Staking out the site where the final murder in the ritual is to take place, Lewton watches as a werewolf murders Al-Khali, who had been tailing him upon his return from "death". Before he can pursue the murderer, Carlotta approaches him, revealing she is the head of a guild devoted to Anu-Anu, a forgotten god worshipped by werewolves such as herself. She reveals he was behind the murders when she called on him – though she needed him to kill Mundy, Malachite and Regin because each threatened her and the cult's plans – and that the god was the one who stabbed him; Carlotta revived him as a werewolf, because she believed he could help the cult. Lewton finds himself forced to witness Anu-Anu conduct the ritual to summon Nylonathatep with the Falchion, but the ritual backfires and causes the beast to emerge in Ankh-Morpork, killing Anu's mortal form and several of the cultists. Lewton discovers a second cult infiltrated Anu-Anu's cult, intent on releasing Nylonathatep for their own purposes, and that the Falchion could not control the creature, let alone banish it, because the missing jewel prevented this. With Two-Conkers's help, Lewton recovers the jewel, and searches for Carlotta, who disappeared with the Falchion. Tracking her down, he finds her in a heated argument with Horst, who threatens to kill her for the relic, forcing him to kill the troll; Carlotta reluctantly gives him the Falchion in return, and allows him to hand her to the Watch for her crimes. With the Falchion restored by the missing jewel, Lewton defeats Nylonathatep with the help of a flying machine created by inventor Leonard da Quirm, saving the city. In the aftermath, Lewton advises Ilsa to leave with Two-Conkers, knowing her husband is not safe in Ankh-Morpork, and watches as the pair leave on the flying machine, while he remarks to Gaspode how the two of them make a "beautiful friendship". The dog merely tells him not to push his luck with that idea.

Perfect Entertainment had enjoyed a working relationship with Terry Pratchett and the Discworld licence from as early as 1993, collaborating closely to develop their first two Discworld games, Discworld (1995) and Discworld II: Missing Presumed...!? (1996). Discworld Noir was developed for Windows 95 and Windows 98. GT Interactive were chosen as publisher due to their strong US presence, as the first two Discworld games had done relatively poorly in America. Chris Bateman, who had worked on Discworld II in a non-lead role, originally suggested using Teppic (the protagonist of Pyramids) as a lead character, though Pratchett disliked the idea. Pratchett sent the developers a story outline and the first draft of the script, wanting a detective story set in Ankh-Morpork. The idea for a film noir theme specifically came from the developers. Bateman wrote the ultimate script, which was then edited by Pratchett. The script was the first one Bateman had written for a video game. With each Discworld game Pratchett became less and less involved, in Noir mainly being involved during the beginning and end of development. The game uses pre-rendered 3D models. Real-time 3D models were unfeasible for the period, as the developers needed the characters to have facial expressions and so likely few people would have computers powerful enough to run the game. A full 3D game would have required simplification of the characters. Utilising some 3D, however, allowed them to explore more with shadow and fog. The backgrounds in the game remained 2D. Most of the voice acting was done by four actors: Rob Brydon, Kate Robbins, Robert Llewelyn, and Nigel Planer. There was one less voice actor in Noir than in Discworld II; however, the heavy amount of dialogue in the game led to more reuse of voice actors in comparison. Audio director Rob Lord also provided additional voices. Robbins, voice actress for every female character in the game, finished her lines in a one-day session. Brydon, who voiced the player character, took a "grueling" week to complete his lines, with the game's main delivery of important information being Lewton's hardboiled monologues. Paul Weir created the soundtrack for the game. Weir studied most of the noir films Discworld Noir drew on. After the release of Discworld Noir for the PC, Perfect Entertainment folded, leaving them unable to patch the game. The company briefly resurfaced as "Teeny Weeny Games", and under this name the game was ported to the PlayStation. The PlayStation version has a lower resolution to the PC game and, in order to fit the game onto one disc (as opposed to the three discs of the PC version), compresses the game's sound and videos. As a result of the closure of GT Interactive, the game was never released outside of Europe.

In a retrospective review in 2002, Bronstring maintained his original rating of 4/5 stars. A 2011 retrospective by Eurogamer's John Walker called it "surprisingly poorly structured", and noted a lack of puzzles. Walker still admitted a "fondness" for the game, however, comparing it favourably to the company's first two Discworld adventure games, noting a lack of "grating knowing tweeness" and an ability to be genuinely funny. In 2011, Adventure Gamers would go on to place it at number 27 in their "Top 100 All-time Adventure Games" list, giving credit to its innovative notepad mechanism, which would become a common element in adventure games. Walker later listed it at number 20 in "The 25 Best Adventure Games Ever Made", praising the voice cast. PC Gamer's Richard Cobbett placed it as 25 in a similar list, commenting "the third Discworld game finally shed its predecessors' fixation with being as much Python as Pratchett". Andy Kelly, also writing for PC Gamer, called it one of the 20 best detective games. Kelly commented: "Its shadowy, rain-soaked setting, Ankh-Morpork, is brilliantly atmospheric, and it manages to both mock film noir and be a loving homage to it." Dave Gilbert called Discworld Noir one of his favourite adventure games, and called it "one of [his] biggest inspirations". Gilbert would eventually create the "Oz noir" adventure game Emerald City Confidential (2009). Kate Berens and Geoff Howard's The Rough Guide to Videogaming includes Discworld Noir as one of its recommended games. Noting the heavy number of conversations, they felt the game played "more like an interactive novel at times" but praised the dialogue and called Ankh-Morpork "beautifully rendered".
