Games

Valve's debut title, Half-Life, launched on November 19, 1998, through publisher Sierra On-Line for Windows. The player steps into the role of Gordon Freeman, a theoretical physicist at the Black Mesa Research Facility, where a botched experiment tears open a dimensional rift and unleashes an alien invasion. Unlike most shooters of the era, the game keeps the player in control of Freeman almost constantly, delivering its story through scripted events rather than cutscenes. Critics praised its visuals, mechanics, and smooth storytelling. It collected more than fifty Game of the Year awards and is widely regarded as a landmark first-person shooter and one of the finest games ever created.

A demo called Half-Life Uplink appeared on February 12, 1999, featuring a chapter absent from the main game. Set in an alternate timeline, it follows Gordon Freeman as he adjusts a transmitter to reach the Lambda Reactor Complex. Once inside, he becomes trapped in a room with a massive Gargantua, with no way out.

The first expansion, Opposing Force, arrived on November 1, 1999, developed by Gearbox Software. It puts players in the boots of US Marine corporal Adrian Shephard, who battles a fresh wave of aliens and black operations forces. Critics received Opposing Force warmly, noting that it set a new standard for expansion packs much like the original game had done for its genre. It took home the Computer Game of the Year Interactive Achievement Award from the Academy of Interactive Arts & Sciences in 2000.

Gearbox also created Blue Shift, Half-Life's second expansion, published by Sierra Entertainment. Announced in 2000, it was originally planned as a bonus campaign for the Dreamcast port of Half-Life. When that port was scrapped, Blue Shift came out for Windows on June 12, 2001. Players control Barney Calhoun, a Black Mesa security guard, during the early events of Half-Life as he tries to flee the facility with a handful of scientists. The package includes a High Definition pack that improves models and textures for Blue Shift, Half-Life, Opposing Force, and Team Fortress. Reviewers liked the atmosphere and upgraded visuals but pointed out the shortage of fresh content and the brief playtime.

Setting

The Half-Life series is widely admired for its richly detailed fictional world and memorable characters, many of whom have become iconic in gaming. The first game centers on Gordon Freeman, a silent theoretical physicist at the Black Mesa Research Facility who is the player character. He is later placed in stasis by the G-Man, a mysterious and morally ambiguous figure with abilities far beyond those of ordinary humans. The original game's expansion packs introduce other protagonists: Corporal Adrian Shephard in Opposing Force and security guard Barney Calhoun in Blue Shift, the latter returning in the Half-Life 2 games.

Half-Life 2 and its sequels present a tighter ensemble fighting the oppressive Combine Empire, including Alyx Vance, a key Resistance member and daughter of former Black Mesa scientist Eli Vance, who stars in Half-Life: Alyx. The series features many alien species, most from the border world Xen. Notable examples are the intelligent Vortigaunts, who often aid Freeman after he frees them from tyranny; headcrabs, parasitic creatures that attach to human heads to create mindless zombies, sometimes weaponized; antlions, large burrowing insectoids; bullsquids, tentacled predators that spit acid; and barnacles, ceiling-dwelling blobs that snare prey with a sticky tongue.

The franchise's enduring symbol is the Greek letter lambda. It first appears on Freeman's HEV suit and as the name of the Lambda Complex, the facility that teleports him to Xen to close the portal. In Half-Life 2, it becomes the emblem of the anti-Combine resistance.

Development

Valve, the company behind the Half-Life series, was started in 1996 in Kirkland, Washington, by Mike Harrington and Gabe Newell, both former Microsoft employees. Not long after forming, they began work on the first Half-Life, deciding to make it a horror-themed 3D action game. They licensed the Quake engine from id Software for the project. The game made a strong impression at the 1997 E3 convention, where its animation system and artificial intelligence were shown off.

This success led to the first expansion pack, Half-Life: Opposing Force, developed by Gearbox Software, a new studio based in Plano, Texas. It was announced on April 15, 1999. Gearbox founder Randy Pitchford explained that Valve handed them the project so Valve could concentrate on future titles. Opposing Force was shown at the 1999 E3 convention, revealing new locations, characters, and story details.

The second expansion, Half-Life: Blue Shift, was also made by Gearbox and announced by its publisher, Sierra Entertainment, on August 30, 2000. Sierra planned to release Blue Shift for the Dreamcast, featuring higher detail models and textures with twice the polygon count of the original Half-Life. After several months of delays, however, Sierra canceled the Dreamcast version on June 16, 2001, and instead put it out for Windows on June 12. Following that, Gearbox started work on a Half-Life game for the PlayStation 2.

This game, Decay, was presented at E3 2001, where Gearbox showed off new model sets that were about twice as detailed as those in Blue Shift. Meanwhile, Valve spent several years secretly developing Half-Life 2. For this, they built a new game engine called Source. It includes a heavily modified version of the Havok physics engine, which adds an extra layer of interactivity in both single-player and online modes.

In the episodic games that came after Half-Life 2, Valve made small adjustments to the engine. In Episode One, they updated Alyx's AI so she could respond to what the player does. This episode runs on an upgraded version of the Source engine, featuring advanced lighting effects and a new version of Valve's facial animation and expression technology.

Film

At the 2013 DICE conference on February 6, 2013, J. J. Abrams and Gabe Newell discussed storytelling in games and film and revealed they were planning a joint project involving a game and a movie. Abrams mentioned having an idea for a game they wanted to develop with Valve, while Newell stated they would explore making either a Portal or a Half-Life movie together. In a March 2016 interview, Abrams confirmed that despite working on other projects, he still intended to direct both films, which were then in the writing stage.

A short film titled Half-Life: Uplink, distinct from the demo with the same name, was created by the British marketing agency Cruise Control and released on March 15, 1999. Sierra later pulled it from distribution after failing to settle licensing issues with Cruise Control. The film received very poor reviews and followed a journalist trying to sneak into the Black Mesa Research Facility to uncover what was happening there.

In early 2009, the Purchase Brothers, a film company based in Toronto, released Half-Life: Escape from City 17, a five-minute film based on Half-Life 2: Episode One. It mixed live-action footage with 3D animation made using the Source SDK and was positively received by Valve. On August 25, 2010, they released a sequel that was nearly 15 minutes long.

Late in 2010, a trailer appeared for Beyond Black Mesa, an independent short film inspired by Half-Life. Directed by Brian Curtin, it focuses on the character Adrian Shephard. The full short film was made available online on January 21, 2011.
