Chapter Summaries

Lin Lixin explained that a compiler update had changed floating-point precision, causing an old door bug, while Carmack demonstrated amusing physics exploits in the new demo. Lin Lixin argued that harmless player-discovered exploits should be treated as features, and the team planned a closed test to see how players felt about them.

• Lin Lixin traced the door's failure to an N Language compiler update that changed floating-point precision, not to altered source code or an intruder.
• Kevin Mitnick and the engineers reacted with relief and frustration after the mysterious bug proved to have a mundane cause.
• Carmack demonstrated that players could ride a plank into the sky and escape the map using the new physics system.
• Christopher worried that the physics exploits would need to be fixed, but Lin Lixin said harmless tricks that players enjoyed should remain.
• Lin Lixin proposed a closed test to determine whether the exploits harmed the experience or functioned as features.

Lin Lixin convinced the team to make Gordon Freeman an ordinary physicist whose signature weapon was a crowbar, then explained how Half-Life’s controlled, mostly indoor levels could support detailed 3D graphics through extensive preprocessing. The chapter left the developers relying on precomputed data and table lookups to keep the game’s performance costs low.

• Lin Lixin defended Gordon Freeman’s scholarly appearance and argued that his role as a Black Mesa researcher made him central to the story.
• Hideo Kojima suggested a pistol, Sam favored a revolver, and Carmack argued for a submachine gun, but Lin Lixin proposed giving Gordon a crowbar first.
• Lin Lixin explained that the crowbar would encourage players to interact with the world, conserve ammunition, and make Gordon’s image distinctive.
• Lin Lixin described how the team used preprocessing, indoor sandboxes, visibility culling, and baked assets to optimize Half-Life’s detailed 3D environments.
• Lin Lixin explained that fixed maps allowed AI routes to be precomputed, reducing pathfinding to table lookups.

Steve and the other invited media representatives explored Amenva’s new campus before attending the Nova Carnival launch, where Amenva revealed gameplay from Half-Life. The demonstration introduced Gordon Freeman as a researcher arriving at the Anomalous Materials Laboratory, and ended as a security guard opened his monorail car.

• Steve rushed to Amenva’s new headquarters with the Electronic Games crew, competing with CNN and Ameline 99 to arrive first.
• Steve and his team toured the campus, gathered material for their coverage, and speculated that the Lambda Area held a new NF game.
• At the evening launch, Amenva showed a Lambda symbol and identified the protagonist as twenty-seven-year-old Gordon Freeman, a theoretical physics Ph.D. from MIT.
• Gameplay footage showed Freeman riding a monorail through the Black Mesa facility toward the Anomalous Materials Laboratory.
• A security guard greeted Freeman and unlocked the car door after the automated announcement instructed him to wait for identity verification.

Microsoft executives Gabe and Mike watched Amenva unveil Half-Life’s real-time staging and immersive sound before trying its demo. Gabe experienced the game’s freely explorable, unbroken train sequence and was impressed by its technology as a new idea began taking root in him.

• Gabe and Mike recognized that Amenva’s demonstration used real-time animation and carefully designed directional sound.
• Lin Lixin revealed that attendees could play a Half-Life demo in the Lambda Zone, and the crowd headed there.
• Gabe entered the Black Mesa Transit System demo and discovered he could move Gordon freely around the moving train carriage.
• Gabe watched the unbroken sequence reveal Black Mesa’s workers and machinery, recognizing it as a technical showcase that built the game’s world.
• Gabe reflected on his growing weariness at Microsoft and felt an idea beginning to take root.

Gabe experienced the opening of Half-Life as Gordon Freeman, from the Black Mesa disaster through the first encounters with alien creatures. He discovered the crowbar’s physics-driven interaction and realized the Headcrabs could parasitize people.

• Gabe reflected on Mike Harrington’s plans to leave Microsoft and wondered whether their software engineering experience could be applied to game development.
• Gabe rode the tram into Black Mesa, donned the orange protective suit, and watched the experiment trigger a disaster that connected Earth to Xen.
• Gabe guided Gordon through the damaged facility, where alarms, debris, explosions, and injured staff made the crisis feel immersive.
• Gabe picked up a red crowbar and smashed through a glass door, marveling at the game’s real-time physics.
• Gabe encountered Headcrabs wearing researchers’ bodies, and recalled seeing one swallow and take over a person’s head in the laboratory.

Gabe and the other playtesters reached the end of Half-Life’s demo, shaken by its monsters and eager to continue. Lin Lixin then revealed that the game had been built to showcase Amenva’s new modular Avk engine, which the company planned to sell to enterprise customers.

• Gabe discovered that touching a wounded security guard gave him a pistol and that the medical station restored his health.
• Gabe spotted the Barnacles covering the sewer ceiling, tested one with a bucket, and then avoided them as he advanced to the elevator.
• Gabe and the other playtesters reached the elevator and saw a message ending their session, then returned to the main stage still wary of things overhead.
• Steve and other attendees praised Half-Life, and Lin Lixin presented Avk as a suite combining physics, animation, artificial intelligence, and destruction tools.
• Lin Lixin announced that Amenva would soon release Avk commercially, initially for enterprise customers such as Industrial Light & Magic and General Motors.

Lin Lixin announced Half-Life’s creator tools and Workshop, celebrated rising internet access, and revealed an Nvabx rebate and the Amenva Museum opening. The press conference then continued with a surprise slide showing a familiar shield from an Nvabx launch title.

• Lin Lixin explained that Half-Life supported real-time scripted content and would launch the cloud-based Workshop for sharing M.
• Lin Lixin announced that internet penetration had passed 20% and praised players for helping Amenva grow.
• Lin Lixin offered a $300 rebate to players who bought an Nvabx in 1985 and promised them lifetime admission to the Amenva Museum.
• Lin Lixin said the museum would open on Presidents' Day at Amenva's old San Francisco headquarters.
• Gabe Newell told Mike he wanted to speak with Lin Lixin about engines and games.
• Lin Lixin returned to the stage and revealed a fantasy shield bearing the Triforce symbol.

Lin Lixin met Gabe Newell and Mike Harrington, who planned to leave Microsoft and enter the game industry by licensing the Half-Life engine. He proposed that they join Amenva’s growing community of game companies, leaving the town’s future as a video game hub in view.

• Lin Lixin recognized Gabe Newell and recounted how Gabe had left Harvard for Microsoft before deciding to enter the game industry with Mike Harrington.
• Lin Lixin agreed that Gabe and Harrington could license the Half-Life engine, which he said was intended to support community creativity.
• Harrington praised the GG merchant service and ames.cm for giving game creators a platform to share their work.
• Lin Lixin asked why the two Microsoft executives wanted to leave, and Harrington said he believed the game industry was poised for its next big wave.
• Lin Lixin proposed that Gabe and Harrington join Amenva, where companies including Activision, Bullfrog, Blizzard, and Rckstar were gathering to build a community for game developers.

Lin Lixin invited Gabe and Harrington to establish a studio at Amenva and gave them a Half-Life PC port as an entrance assessment. On Presidents' Day, Half-Life sold 5.11 million copies in twenty-four hours, setting a new entertainment revenue record, while Amenva opened its video game museum.

• Lin Lixin offered Gabe and Harrington the chance to form a studio at Amenva under a model that gave teams creative freedom but made them responsible for later development costs.
• Lin Lixin set porting Half-Life to PC and making it run on an i486 as Gabe and Harrington’s entrance assessment.
• Amenva’s long-awaited The Legend of Zelda project drew attention, though Lin Lixin and Sam revealed no details beyond saying they had created its folder.
• On Presidents' Day, Half-Life sold 5.11 million copies in twenty-four hours, earning over $250 million and setting a Guinness World Record for the highest-grossing entertainment product in a day.
• Amenva officially opened its video game museum, featuring exhibits on gaming history, game media, and a recreated arcade.

Lin Lixin visited Activision and reviewed the growing library of browser games on ames.cm. He realized that the absence of accessible tools was keeping animators from making games, and proposed a NvaScript-based engine or software to lower that barrier.

• Lin Lixin decided to visit Activision to discuss the internet and the future of online games.
• At Activision’s headquarters, Lin Lixin browsed ames.cm and was surprised by how many games creators had submitted.
• David explained how GG revenue and player traffic supported creators and made ames.cm a low-risk publishing platform.
• Lin Lixin tried popular browser games and concluded that their familiar genres and limited styles reflected the platform’s technical constraints.
• Lin Lixin realized that the lack of Flash had kept animators from entering game development and proposed accessible NvaScript-based game-making software to David.

Lin Lixin showed the Activision developers how a game built from simple buttons and branching animations could still offer meaningful interaction. He proposed a “Grow-style game,” where the order of a few player choices produced many different worldlines.

• David argued that games differed from animation through interactivity, while Lin Lixin explained that meaningful player feedback did not require complicated controls.
• Lin Lixin demonstrated a planet-building game in which players clicked a bucket, windmill, and pickaxe to change the world and shape a civilization.
• Lin Lixin showed how changing the order of those choices could lead to different outcomes, including a failed civilization with a windmill turned into a religious site.
• The developers realized that branching sequences formed a state tree with many possible worldlines, and Lin Lixin called the proposed project a “Grow-style game.”

Lin Lixin explained how browser games had to keep failure from driving players away, then introduced Nva Flash as a simpler tool for creating browser games. The launch event ended with David unveiling its software box while reporters wondered whether Lin Lixin was working on a sequel to The Legend of Zelda.

• Lin Lixin described Grow Sphere games and explained that browser games needed short intervals between failure and retries to keep players engaged.
• David argued that browser games had low costs for both playing and leaving, so harsh negative feedback could make players switch away.
• Lin Lixin praised the team and discussed canvas-api, explaining how NvaScript had made drawing graphics easier than using 6502 assembly.
• David took the stage at the launch event and introduced Nva Flash as the world's first browser game development engine.
• A reporter asked whether Lin Lixin was working on the rumored The Legend of Zelda sequel, and David declined to discuss it before presenting a red-and-gold software box.

David introduced Amenva’s Flash software, demonstrating how it let users quickly create animations and interactive games, while Lin Lixin saw it as a step toward future internet media and streaming. As Flash began attracting public attention, Luo Nan noticed a new game on ames.cm and recognized its creator name, “Lin.”

• David demonstrated Flash’s tween animation and interactive features, showing reporters how quickly users could create a basketball game without coding.
• David explained that Flash used canvas and vectors, included an NvaScript interpreter, and could publish reviewed projects through Activision to ames.cm with GG revenue sharing.
• Lin Lixin regarded Flash as a wrapper around canvas and a transitional tool while streaming media remained impractical on existing bandwidth and hardware.
• A new game called “r valley” appeared on ames.cm as Flash entered the public eye.
• Luo Nan checked the new releases chart and focused on the creator name “Lin” listed on the game.

Luo Nan tried an educational game about how different academic disciplines could cooperate to develop a valley. After seeing the electrical and design disciplines interact, he wondered how mathematics might contribute.

• Luo Nan opened a game introduced as a way to show students different disciplines and the importance of cooperation.
• Luo Nan selected the electrical engineering discipline, whose blue figure built a signal tower and tested a Motorola MicroTAC.
• Luo Nan selected the design discipline, whose white figure surveyed the valley and began drawing plans.
• The electrical figure upgraded its tower and phone, then emailed the design figure, leading Luo Nan to recognize a possible synergy between disciplines.
• Luo Nan examined the mathematical and physical sciences option and questioned how mathematics could help develop a valley.

Luo Nan struggled to make progress in a civilization-building game until his architect father advised him to start with design and coordinate the disciplines. Their cooperation transformed the empty valley into a thriving settlement, and Luo Nan discovered that he had only begun to explore the game’s many endings.

• Luo Nan watched the disciplines build a clinic, a car, and infrastructure, but his first attempt ended with most levels low or at zero, so he reset the game.
• Luo Nan’s father suggested sending design out first and explained that designers created blueprints for construction crews to realize.
• Luo Nan sent out civil engineering and electrical engineering, and design responded to their signal by posting blueprints in the valley.
• Civil engineering used the blueprints to build a circular road, and engineering, design, and electrical engineering worked together to create a car that drove around it.
• The disciplines continued cooperating to develop the valley, bringing every level to max and building a vast settlement with an underground city, public facilities, and transit lines.

Lin Lixin reviewed Amenva’s growing game lineup and considered the many possibilities opened up by the Nvafsin’s fifth-generation hardware. He decided to make a realistic driving simulator, leaving the chapter with Gran Turismo in mind as the perfect fit.

• Lin Lixin reviewed Flash’s steady sales growth and discussed a possible new series with a server at a family restaurant.
• He considered the many games Amenva could develop for the Nvafsin, including sequels, action-adventure games, and new genres made possible by stronger hardware.
• Lin Lixin noticed Amenva had not made a first-party console racing game since Need for Speed and considered updating the series.
• With General Motors providing access to real car models and the Nvafsin controller offering vibration, Lin Lixin decided Amenva could pursue a more immersive driving simulation.
• Lin Lixin recalled Gran Turismo’s success and realistic approach to cars, tracks, and handling, then decided it would suit the Nvafsin and give him a chance to relax.

Lin Lixin invited General Motors president Russell to help create Gran Turismo, a realistic racing game built around authentic driving feel. After trying the cars on Amenva’s campus track, Russell weighed the risks of sharing GM’s engineering data against the game’s potential to promote its cars.

• Russell arrived at Amenva in a new Camaro Z28 and found Lin Lixin and Vivian preparing to leave with their luggage.
• Lin Lixin explained that he wanted to feature the Camaro because ordinary people knew it better than the Corvette, and invited Russell to drive on the campus track.
• Lin Lixin and Russell tested the Camaro and Corvette ZR-1, experiencing the precise feedback and slower pace of realistic driving.
• Lin Lixin described his plan to use Avk for realistic physics and said Amenva wanted to explore slower, more immersive games for Nvafsin.
• Lin Lixin asked General Motors for engineering data on its entire lineup and guidance from a full engineering team.
• Russell recognized the risks of sharing sensitive data but considered how Gran Turismo could showcase GM cars and influence future buyers.

Lin Lixin brought his team to Germany to begin work on a realistic driving simulator, using specialized survey vehicles to digitally reproduce real-world circuits. At the Nürburgring, the team settled in to study the Nordschleife and its changing road conditions as they prepared to create a game centered on cars and car culture.

• Lin Lixin showed Russell Amenva’s lidar-equipped survey SUV and explained how its equipment would capture circuit data.
• Lin Lixin and the team traveled through Rhineland-Palatinate and arrived at the Nürburgring Nordschleife.
• Nürburgring staff welcomed the group after Amenva and General Motors arranged to acquire circuit data and test vehicles there.
• Lin Lixin told the circuit management that Amenva’s development team would work at the Nordschleife throughout the project.
• Lin Lixin planned to reproduce cars, their specifications, and the driving differences caused by road surfaces and weather in the simulator.

Lin Lixin discovered that the demo’s realistic physics made its controls difficult for ordinary players and reworked the input system with driving assists. Vivian then drove comfortably through a corner, leaving the team with a more playable version that felt more real to players despite being less faithful to reality.

• Lin Lixin noticed that Sam, Vivian, Sid, and other testers repeatedly crashed, while experienced drivers handled the demo more easily.
• Lin Lixin identified late braking as a cause of the crashes and asked Sabine Schmitz to compare the demo with real driving.
• Sabine explained that a screen and controller could not provide bodily inertia, steering resistance, or tire feedback, even though the car responded precisely to inputs.
• Lin Lixin tested the demo as a novice and concluded that the team should prioritize the player's experience over reproducing real driving exactly.
• Lin Lixin reworked the input system and added driving assists, after which Vivian smoothly cleared the corner that had caused her to crash.

Amenva gathered automakers and racing experts at several famous circuits to collect data for a new racing game, while rumors of the project spread through gaming media. After the teams returned to California, Amenva released a promotional video showing a customized Chevrolet Camaro at the Nürburgring Nordschleife.

• Amenva booked the Nürburgring Nordschleife and had professional drivers, including Lin Lixin and Sabine, test cars while collecting data.
• BMW sent Bernd and its chief engineer to negotiate a collaboration, followed by Porsche and Volkswagen, as automakers gathered at the circuit.
• Amenva's developers, engineers, artists, testers, and Hans Zimmer worked on the game's mechanics, vehicle models, physics, circuits, and music as leaks fueled media coverage.
• In April, Amenva's teams returned to California from the Nürburgring, Japan, and the United States, and Lucas's film crew returned with them.
• On April 10, Amenva released a promotional video featuring a modified Chevrolet Camaro covered in Easter eggs driving to the Nürburgring Nordschleife's starting point.
