Half-Life is a science fiction first-person shooter computer game series which consists of two full games, two episodic games, and three third-party made expansions, as well as a number of demos featuring exclusive content. The series has been ongoing since 1998. Most games and expansions in the series were developed by Valve Corporation and published by Sierra Studios, although some expansions were produced by Gearbox Software. Electronic Arts also took over distribution of the games in the series from Sierra from 2005 onwards. The series was initially released for the PC, but console ports of most installments have also been released.

The main protagonist of the Half-Life series is Gordon Freeman, a theoretical physicist and employee of the Black Mesa Research Facility. All expansion packs for the original game feature playable characters other than Freeman.

Plot

The Half-Life series begins in the first decade of the 21st century, at the fictional Black Mesa Research Facility in New Mexico. Gordon Freeman, a recently employed theoretical physicist, is involved in an experiment analyzing an unknown crystalline artifact; however, when the anti-mass spectrometer beam contacts the crystal, it opens a dimensional rift between Black Mesa and another world called Xen, causing monsters to swarm Black Mesa and kill many of the facility's personnel. Attempts by the Black Mesa personnel to close the rift are unsuccessful, leading to a specialist US Marines unit being sent in to silence the facility, including any survivors from the science team. Freeman fights through the facility to meet with several other scientists, who decide to travel to the alien dimension to stop the aliens. On Xen, Freeman eliminates the alien "leader" and is confronted by the G-Man, who offers Freeman employment before putting him into stasis.^[1] Back in Black Mesa, a second alien race begins an invasion, but are stopped when a Marine corporal, Adrian Shephard, collapses their portal in the facility. The G-Man then destroys Black Mesa with a nuclear warhead, and detains Shephard in stasis.

Nearly twenty years later,^[1] the G-Man brings Freeman out of stasis and inserts him into a dystopian Earth ruled by the Combine, another alien race that used the dimensional rift caused at Black Mesa to conquer Earth in the interim. In the Eastern European settlement City 17, Freeman meets surviving members of the Black Mesa incident, including Isaac Kleiner, Barney Calhoun, Eli Vance and his daughter Alyx Vance, and aids in the human resistance against Combine rule. The Xen aliens, the Vortigaunts, who have been enslaved by the Combine, also assist the resistance. When his presence is made known to former Black Mesa administrator and Combine spokesman Wallace Breen, Freeman becomes a prime target for the Combine forces. Eventually, Freeman sparks a full revolution amongst the human citizens. Eli Vance and his daughter are subsequently captured by the Combine, and Freeman helps the resistance forces attack the Combine's Citadel to rescue them. Breen attempts to flee in a teleporter, but is presumed dead after Freeman destroys the dark energy reactor at the Citadel's top. The G-Man then arrives to extract Freeman before he is engulfed in the explosion, but is interrupted when Vortigaunts liberate Freeman from stasis and place both him and Alyx Vance at the bottom of the Citadel. The two then attempt to stabilize the Combine's primary reactor while the citizens evacuate the city, discovering that the Combine are attempting to destroy the reactor to call for reinforcements from the Combine's native dimension. After downloading critical data, they move through the war-torn city to the train station to take the last train out of the city. The Combine then destroy the reactor and thus both the Citadel and the city; the resulting explosion causes the train to derail.

Freeman awakens in one of the wrecked train cars with Alyx outside, where a forming superportal is visible from where the Citadel used to stand. They begin a journey through the White Forest to a resistance-controlled missile base in the nearby mountains. Along the way, Freeman and Alyx are ambushed and Alyx is severely injured. However, a group of Vortigaunts are able to heal her. They are able to reach the resistance base and deliver the data, which contains the codes to destroy the portal as well as information on the Borealis, an enigmatic research vessel operated by Black Mesa's rival, Aperture Science. The base then launches a satellite that is able to shut down the superportal, cutting off the Combine from outside assistance. However, as Alyx and Freeman prepare to travel to the Arctic and investigate the Borealis, they are attacked by Combine Advisors, who kill Eli Vance before being driven off by Alyx's pet robot, Dog.

Games

The Half-Life series includes a core set of titles which carry the main storyline. These games were released in chronological order, either portraying the events of one game from the perspective of a different character, or following on from the events that are depicted in the previous title. As of May 2010, the main series consists of the original video game and its sequel, as well as three expansion packs and two episodic games. A third episodic game remains in development. In addition, several spin-off titles have been released. These vary in nature, consisting of a platform game, technology demonstration, and a series of puzzle games. The original game and its expansions all use Valve's GoldSrc game engine, a heavily modified Quake engine. The later games accompanying the sequel all use Valve's proprietary Source engine.

GoldSrc games

Half-Life is the first title for the series, and was the debut title of Valve Software. First released on November 19, 1998, Half-Life follows Gordon Freeman, a theoretical physicist, after the Black Mesa Research Facility accidentally causes a dimensional rift which allows the facility to be invaded by aliens. Freeman consequently attempts to survive the slaughter and resolve the situation. The game was originally published by Sierra Studios and released for Windows, although Gearbox Software would later port the game to PlayStation 2 in 2001.^[2] Valve themselves later converted the game to utilize their Source engine.^[3] Half-Life received critical acclaim upon release, critics hailing its overall presentation and numerous scripted sequences.^[4] The game won over 50 Game of the Year awards^[5] and its gameplay has influenced first-person shooters for years to come. Half-Life has since been regarded as one of the greatest games of all time.^[6][7]

Half-Life was followed by an expansion pack, Half-Life: Opposing Force, on November 1, 1999.^[8] Unlike Half-Life, Opposing Force was developed by Gearbox Software, although it was still published by Sierra Studios. Opposing Force was first announced as a mission pack for Half-Life in April 1999, and was released for the Windows version of the game.^[9] The player no longer assumes the role of Gordon Freeman, but rather sees the later events of the first game from the perspective of a US Marine corporal, Adrian Shephard. Shephard is initially assigned to cover up the events at Black Mesa, but is soon left isolated and has to fight to survive against a new group of alien invaders and black operations units. Opposing Force was received favorably by critics,^[10] many citing the game as being as influential on setting expansion pack standards as the original game had been in influencing the overall genre.^[11][12][13] The game won the Computer Game of the Year Interactive Achievement Award of 2000 from the Academy of Interactive Arts & Sciences.^[14]

Gearbox later went on to develop Half-Life: Blue Shift, Half-Life's second expansion pack. Like Opposing Force, Blue Shift was published by Sierra Entertainment. Announced in 2000, the game was initially developed as an add-on for a Dreamcast port of Half-Life;^[15] however, the port was cancelled and Blue Shift was instead released for Windows on June 12, 2001.^[16][17] Blue Shift puts the player in the position of Barney Calhoun, a security guard working at Black Mesa. The game takes place within the early parts of Half-Life, with Calhoun attempting to escape the facility with a small group of scientists. Blue Shift also includes a High Definition pack, which upgrades the quality of the models and textures in both Blue Shift and the preceding games in the series.^[18] Critics gave Blue Shift a mixed but favorable reception,^[19] praising the game's atmosphere and the inclusion of the High Definition pack, but criticizing the otherwise lack of new content and short length of the story.^[20][21][22]

The third and final expansion for Half-Life was Half-Life: Decay. The game was again developed by Gearbox and published by Sierra. However, unlike previous titles, Decay is only available with the PlayStation 2 version of Half-Life.^[23] Decay is unique within the Half-Life series as the only cooperative game—two players must work together to progress through the game.^[24] Decay focuses on two of Freeman's colleagues, Gina Cross and Colette Green, as the two work with other scientists to counter the effects of the dimensional rift and ultimately attempt to close it. Released on November 14, 2001, Decay received a weak but overall positive reception from critics, many reviewers stating that it was fun to play through with a friend, but that the game's more puzzle-orientated gameplay detracted from the overall experience.^[25][26][27] An unofficial Windows port of the game was released in September 2008.^[28]

Source games

On November 16, 2004, Valve released Half-Life 2, the sequel to the original game. The game had a six-year development cycle, which saw several delays and the leak of the game's source code. Half-Life 2 returns the player to the role of Gordon Freeman, now employed by the G-Man. Set twenty years after the original game,^[1] Earth has been occupied by the Combine, a transdimensional race that exploited the events of the first game to invade. The G-Man inserts Freeman into City 17 in Eastern Europe to combat the Combine occupation. Half-Life 2 garnered near-unanimous positive reviews and received critical acclaim, winning over 35 Game of the Year awards for 2004. The game has been critically praised for its advances in computer animation, sound, narration, computer graphics, artificial intelligence, and physics. Half-Life 2 was the first title to use Valve's Steam content delivery system, a system that eventually led to Valve falling out with publisher Sierra Entertainment.

Following Half-Life 2, the series was continued using a pair of episodic games, with a third planned. Half-Life 2: Episode One was the first of these, set around City 17 after the events of the original game, in which Freeman and Alyx Vance must attempt to escape the city after a dark energy reactor core they damaged at the end of Half-Life 2 threatens to destroy the city. It was released on June 1, 2006, and introduced several new graphical effects including new lighting features and more advanced facial animation. Episode One received a generally positive critical reaction, although the game's short length was a point of common criticism.

The second episodic game, Half-Life 2: Episode Two, continues the story from where Episode One ended. It was released on October 10, 2007, bundled with the games Portal and Team Fortress 2 as well as Half-Life 2 and Episode One in the package The Orange Box, which was released for Windows PCs and the Xbox 360 and PlayStation 3 consoles. The game was again developed by Valve, and distributed using both Steam and Electronic Arts. Continuing with Valve's policy of orienting each episode around a particular theme or set of technologies, Episode Two focuses on expansive environments, travel and less linear play. As Gordon Freeman, the player travels with Alyx Vance away from the ruins of City 17 into the surrounding countryside, pursued by Combine forces. Episode Two's new technologies and gameplay features were praised by reviewers; however, the short length of the game was again a point of criticism.

Half-Life 2: Episode Three is the third and final installment in the series of episodic expansions.^[29] It is planned as the last episode in the story arc, although not necessarily the end of the Half-Life franchise.^[30] No release date or other details have been announced, though some concept art has surfaced^[31][32] as well as the possible incorporation of sign language into the game by including a deaf character.^[33] In a March 2010 interview, Newell spoke of "broadening the emotional palette" of the series, and how the next Half-Life game may return to "genuinely scaring the player".^[34]

Spin-off games

The success of the Half-Life series has spurred the creation of several spin-off games for Half-Life 2. Codename: Gordon is a two-dimensional Flash sidescroller shooter produced by Nuclearvision Entertainment, and was released over Valve's Steam online delivery system on May 17, 2004, as a promotional game for the then-upcoming Half-Life 2. The developer has since gone bankrupt, but the game itself can still be installed via a direct link to Steam, despite not being listed in the store.^[35] Codename: Gordon was well received by reviewers and the public, and attracted over 600,000 players in the first three weeks after its release. Reviewers praised the game for its gameplay and unique dialog style, but also criticized it for its improper optimization, and lack of opponent variety.

Half-Life 2: Lost Coast is a technology demonstration, developed by Valve to display new high dynamic range rendering and a variety of other features. Valve asked for feedback as to whether these features should be used in their future games. The level was designed with a variety of appropriate environments to emphasize these effects. Consisting of a single map, Lost Coast was originally to be part of Half-Life 2, but was dropped during development. The game follows Gordon Freeman as he travels up a coastal cliff to destroy a Combine artillery launcher in a monastery, which is firing on the town of St. Olga. Released over Steam on October 27, 2005, the level received a generally positive reception, and there was consensus among fans that the new features should be implemented into future games released by Valve.

Portal is a puzzle game set in the Half-Life universe, developed by Valve Corporation. It was initially released alongside Episode Two in The Orange Box on October 10, 2007. The player controls a test subject named Chell as she moves through the laboratories of Black Mesa's primary rival, Aperture Science, completing various tests with a device that allows her to create linked portals in physical space. In the later stages of the game, the player battles GLaDOS, a corrupt artificial intelligence computer that monitors her every move. The game is the spiritual successor to Narbacular Drop, with many of the same team members working on the game. Portal has been acclaimed as one of the most original games in 2007, receiving praise for its unique gameplay and darkly humorous story. An Xbox Live Arcade expansion was released on October 22, 2008, whilst a sequel to Portal, Portal 2, has also been confirmed.^[36]

Development

The video game development company behind the Half-Life series, Valve Corporation, was founded in 1996 in Kirkland, Washington by former Microsoft employees Mike Harrington and Gabe Newell. They began working on the first game of the series soon after the company's formation, and settled on a concept for a horror-themed 3D action game, using the Quake engine as licensed by id Software. The game was a hit at the 1997 E3 convention, where its animation system and artificial intelligence were demonstrated.^[37] The game's success led to its first expansion pack, Half-Life: Opposing Force, which was developed by Gearbox Software, a then-new company based in Plano, Texas, and announced on April 15, 1999.^[38] Gearbox founder Randy Pitchford said in an interview that he believed Valve gave them the opportunity to produce a sequel to Half-Life to allow Valve to focus on future titles.^[39] The game was demonstrated at the 1999 E3 convention, where new locations, characters, and the story were revealed.^[40]

The second Half-Life expansion pack, Half-Life: Blue Shift, was again developed by Gearbox Software and announced by its publisher, Sierra Entertainment, on August 30, 2000.^[41] Sierra intended to release Blue Shift for the Dreamcast, and it was set to include higher detail models and textures^[42] that were double the polygon count of the models from Half-Life.^[43] However, after several months of delays, Sierra terminated development on the Dreamcast version of Blue Shift on June 16, 2001,^[16] and the company instead released Blue Shift for the PC on June 12, 2001.^[17] Afterward, Gearbox began working on a Half-Life game for the PlayStation 2. The game, titled Decay, was showcased at E3 2001, where Gearbox demonstrated the game's use of new model sets,^[44] which were around twice as detailed as those in Blue Shift.^[45]

For several years, Valve secretly worked on the sequel to the original Half-Life, titled Half-Life 2. For the game, Valve developed a new game engine called the Source engine, which handles the game's visual, audio, and artificial intelligence elements. The Source engine comes packaged with a heavily modified version of the Havok physics engine that allows for an extra dimension of interactivity in both single-player and online environments.^[46] In the trilogy of episodic games that followed Half-Life 2, Valve made minor tweaks to the game's engine. In Half-Life 2: Episode One, Valve modified Alyx's AI to allow her to react to the player's actions because of her significant involvement in the game.^[47] The game runs on an upgraded version of Valve's proprietary Source engine, and features both the engine's advanced lighting effects, and a new version of its facial animation/expression technology.^[48]

Film

Valve’s CEO and co-founder Gabe Newell told PC Gamer that they'll make a Half-Life movie. ^[49]

Cultural Influence and reception

A short film based upon Half-Life, titled Half-Life: Uplink, was developed by Cruise Control, a British marketing agency, and released on March 15, 1999. However, Sierra withdrew it from circulation, after itself and Valve had failed to resolve licensing issues with Cruise Control over the film. The critical reception of the film was very poor. The film's plot was that of a journalist attempting to infiltrate the Black Mesa Research Facility and discover what was happening there.^{[50][51][52][53]}

In early 2009, the Purchase Brothers, a Toronto-based film company, released a five-minute film based on Half-Life 2: Episode One called Half-Life: Escape from City-17. The film combines live-action footage with 3D animation created using the Source SDK for the video game.^[54] It was well received by Valve.^[55]
