Half Life

Half-Life is a science fiction first-person shooter video game developed by Valve Corporation, the company's debut product and the first in the Half-Life series. First released by Sierra Studios, the game was also released for the PlayStation 2. In Half-Life, players assume the role of Dr. Gordon Freeman, a theoretical physicist who must fight his way out of a secret underground research facility whose research and experiments into teleportation technology have gone disastrously wrong.
Valve, set up by former Microsoft employees, had difficulty finding a publisher for the game, with many believing that it was "too ambitious" a project. Sierra On-Line eventually signed the game after expressing interest in making a 3D action game. The game had its first major public appearance at the 1997 Electronic Entertainment Expo. Designed for Windows, the game uses a heavily modified version of the Quake engine called GoldSrc.
On its release, critics hailed its overall presentation and numerous scripted sequences, and it won over 50 PC Game of the Year awards. Its gameplay influenced the design of first-person shooters for years after its release, and it is widely considered to be one of the greatest computer games of all time. As of 16 November 2004, Half-Life sold eight million copies, and 9.3 million copies by December 2008. As of 14 July 2006, the Half-Life franchise has sold over 20 million units. Half-Life was followed by the 2004 sequel Half-Life 2, which also received critical acclaim. Half-Life has had a notable cultural impact with its community mods and sequels spawning a large fanbase and cult following.
==Gameplay==
Half-Life is a first-person shooter that requires the player to perform combat tasks and puzzle solving to advance through the game. Unlike its peers at the time, Half-Life used scripted sequences, such as a Bullsquid ramming down a door, to advance major plot points. While most contemporary first-person shooters relied on cut-scene intermissions to detail their plotlines, Half-Life's story is told entirely by means of scripted sequences, keeping the player in control of the first-person viewpoint. In line with this, the game has no cut-scenes, and the player rarely loses the ability to control Gordon, who never speaks and is never actually seen in the game; the player sees "through his eyes" for the entire length of the game. Half-Life has no "levels"; it instead divides the game by chapters, whose titles flash on the screen as the player moves through the game. Progress through the world is continuous, except for breaks for loading.
The game regularly integrates puzzles, such as navigating a maze of conveyor belts, or using nearby boxes to build a small staircase to the next area the player must travel to. Some puzzles involve using the environment to kill an enemy, like turning on a steam valve to spray hot steam at their enemies. There are few "bosses" in the conventional sense, where the player defeats a superior opponent by direct confrontation. Instead, such organisms occasionally define chapters, and the player is generally expected to use the terrain, rather than firepower, to kill the "boss". Late in the game, the player receives a "long jump module" for the HEV suit, which allows the player to increase the horizontal distance and speed of jumps by crouching before jumping. The player must rely on this ability to navigate various platformer-style jumping puzzles in Xen toward the end of the game.
For the most part the player battles through the game alone, but is occasionally assisted by non-player characters; specifically security guards and scientists who help the player, the former who will fight alongside and both who can assist in reaching new areas and impart relevant plot information. A wide array of enemies populate the game including parasites of Xen such as headcrabs, bullsquids, headcrab zombies and Vortigaunts. The player also faces human opponents, in particular Hazardous Environment Combat Unit (HECU) Marines and black ops assassins who are dispatched to contain the extra-dimensional threats and silence all witnesses.
The iconic weapon of Half-Life is the crowbar, which can be used for melee fighting as well as for clearing obstructions and breaking apart boxes and crates, which sometimes contain useful items. The game also features numerous conventional weapons, such as the Glock 17 pistol, Franchi SPAS-12 shotgun, MP5 submachine gun with an attached M203 grenade launcher, Colt Python .357 Magnum revolver, and rocket launcher as well as unusual weapons ranging from a crossbow to weapons from Xen and genetically engineered weapons; such as an organic homing gun and flesh-eating parasites called "Snarks". Two experimental weapons, the tau cannon (nicknamed the Gauss gun) and the Gluon Gun, are built by the scientists in the facility and are acquired by the player late in the game.
==Synopsis==
===Setting===
Most of the game is set in a remote desert area of New Mexico in the Black Mesa Research Facility, a fictional complex that bears many similarities to both the Los Alamos National Laboratory and Area 51, at some point between the years 2000 and 2009. The game's protagonist is the theoretical physicist Gordon Freeman, an MIT graduate. Freeman becomes one of the survivors of an experiment at Black Mesa that goes horribly wrong, when an unexpected "resonance cascade"—a fictitious phenomenon —rips dimensional seams, devastating the facility. Aliens from another dimension known as Xen subsequently enter the facility through these dimensional seams (an event known as the "Black Mesa incident").
As Freeman tries to make his way out of the ruined facility, he soon discovers that he is caught between two sides: the hostile aliens and the Hazardous Environment Combat Unit, a United States Marine Corps Special Operations division dispatched to cover up the incident by eliminating the organisms, as well as Dr. Freeman and the other surviving Black Mesa personnel. Throughout the game, a mysterious figure known (but not actually referred to in-game) as the "G-Man" regularly appears, and seems to be monitoring Freeman's progress. Ultimately, Freeman uses the cooperation of surviving scientists and security officers to work his way towards the mysterious "Lambda Complex" of Black Mesa (signified with the Greek "λ" character), where a team of survivors teleport him to the alien world Xen to kill the Nihilanth, the semi-physical entity keeping Xen's side of the dimensional rift open.
===Plot===
Gordon Freeman arrives late for work at the Black Mesa Research Facility at 8:47 A.M., using its tram system. He acquires his Hazardous Environment suit before proceeding to the test chamber of the Anomalous Materials Lab, to assist in an experiment. He is tasked with pushing a non-standard specimen into the scanning beam of the Anti-Mass Spectrometer for analysis. This creates a sudden catastrophe called a "resonance cascade", opening a portal between Earth and a dimension called Xen. Freeman is sporadically teleported there and catches glimpses of various alien life-forms, including a circle of Vortigaunts, shortly before blacking out.
Freeman awakens in the ruined test chamber and surveys the destroyed lab, strewn with the bodies of scientists and security personnel. Finding survivors, Freeman learns that communication lines to the outside world are completely cut and is encouraged to head to the surface for help because of his suit. His journey consists of sidestepping Black Mesa's structural damage and defending himself against hostile Xen creatures suddenly teleporting into the area. Other survivors along the way claim that a rescue team has been dispatched, only to discover that the Hazardous Environment Combat Unit, which has taken control of Black Mesa, is killing both the organisms and the employees there as part of a government cover-up. Freeman fights the Marines before reaching the surface of Black Mesa, where he learns that scientists from the Lambda Complex may have the means to resolve the problems created by the cascade. Gordon travels to the other end of the facility to assist them. However, Gordon encounters several hurdles throughout the facility, such as reactivating a rocket engine test facility to destroy a trio of giant Tentacles, using an aging railway system in order to launch a crucial satellite rocket, and fighting a group of Black Ops soldiers, before he is captured by Marines and dumped in a garbage compactor. Gordon escapes safely and makes his way to an older part of the facility where he discovers an extensive collection of specimens collected from Xen, long before the resonance cascade.
Reaching the surface once more, Gordon finds that the area has become a warzone. Despite calling for reinforcements, the Marines are being overwhelmed by an alien military force. By scaling cliffs and navigating destroyed buildings, Gordon reaches safety underground. The Marines begin to pull out of Black Mesa and airstrikes begin, while Gordon goes through underground water channels as aliens pick off the remaining Marines. Freeman arrives at the Lambda Complex, in which scientists developed the teleportation technology that allowed them to travel to Xen in the first place. He also encounters another group of Black Ops. After meeting the remaining personnel, Gordon is told that the satellite he launched failed to reverse the effects of the resonance cascade because an immensely powerful being on the other side of the rift is keeping it open. Gordon must kill this being to stop the Xenian invasion. The scientists activate the teleporter and Gordon is transported to Xen.
Entering the borderworld Xen, Gordon encounters many of the organisms that had been brought into Black Mesa, as well as the remains of HEV-wearing researchers that came before him. He fights against Gonarch, a huge headcrab with a large egg sac, fights his way through an alien camp, and arrives at a massive alien factory, which is creating the Alien Grunt soldiers. After fighting his way through levitating creatures, he finds a giant portal and enters it. In a vast cave, Gordon confronts the Nihilanth, the entity maintaining the rift, and destroys it. As the Nihilanth dies, it explodes in a giant green blast which knocks Gordon unconscious.
Gordon awakens, stripped of his gear, in the presence of the G-Man, who has been watching over Gordon, appearing at least once in each chapter. The G-Man praises Freeman's actions in Xen. He explains that his "employers", believing that Gordon has "limitless potential", have authorized him to offer Freeman a job. He is also given a choice to refuse, but is told that should he refuse this offer, he will be given a battle where he has "no chance of winning". While this is taking place, the scenery they are standing in warps to various Xen locales and other dimensions, ending in one of the tram cars from the beginning of Freeman's day, flying through the Multiverse. After accepting, the screen goes black and the G-Man is heard to say, "Wisely done, Mr. Freeman. I will see you up ahead." Players who decline The G-Man's offer find themselves unarmed and surrounded by hordes of hostile creatures, as The G-man says, "Well, it looks like we won't be working together. No regrets, Mr. Freeman."
==Development==
Half-Life was the first product of Valve Software, a software developer based at Kirkland, Washington founded in 1996 by former Microsoft employees Mike Harrington and Gabe Newell. Valve settled on a concept for a horror-themed 3D action game using the Quake engine licensed from id Software. Valve eventually modified the engine a great deal, notably adding skeletal animation and Direct3D support; a developer stated in a PC Accelerator magazine preview that seventy percent of the engine code was rewritten. Valve initially struggled to find a publisher, many believing their project too ambitious for a studio headed by newcomers to the video game industry; however, Sierra On-Line had been very interested in making a 3D action game, especially one based on the Quake engine, and signed Valve for a one-game deal.
The original code name for Half-Life was Quiver, after the Arrowhead military base from Stephen King's novella The Mist, an early inspiration for the game. Gabe Newell explained that the name Half-Life was chosen because it was evocative of the theme, not clichéd, and had a corresponding visual symbol: the Greek letter λ (lower-case lambda), which represents the decay constant in the half-life equation. According to one of the game's designers, Harry Teasley, Doom was a huge influence on most of the team working on Half-Life. According to Teasley, they wanted Half-Life to "scare you like Doom did". Newell felt that "Half-Life in many ways was a reactionary response to the trivialization of the experience of the first person genre. Many of us had fallen in love with videogames because of the phenomenological possibilities of the field, and felt like the industry was reducing the experiences to least common denominators rather than exploring those possibilities. Our hope was that building worlds and characters would be more compelling than building shooting galleries."
The first public appearances of Half-Life came in early 1997; it was a hit at Electronic Entertainment Expo that year, where they primarily demonstrated the animation system and artificial intelligence. Valve Software hired science fiction author Marc Laidlaw in August 1997 to work on the game's characters and level design. Half-Life's soundtrack was composed by Kelly Bailey. Half-Life was originally planned to be shipped in late 1997, to compete with Quake II, but was postponed when Valve decided the game needed significant revision.
In a 2003 Making Of... feature in Edge, Newell discusses the team's early difficulties with level design. In desperation, a single level was assembled including every weapon, enemy, scripted event, and level design quirk that the designers had come up with so far. This single level inspired the studio to press on with the game. As a result, the studio completely reworked the game's artificial intelligence and levels in the year leading up to its release. At E3 1998 it was given Game Critics Awards for "Best PC Game" and "Best Action Game". The release date was delayed several times in 1998 before the game was finally released in November of that year.
Two official demos for Half-Life were released. The first demo, Half-Life: Day One, contained the first one-fifth of the full game, and was meant only for distribution with certain graphic cards. The second demo was released on February 12, 1999. Entitled Half-Life: Uplink, the demonstration featured many of the weapons and non-player characters in Half-Life. Set 48 hours into the game, Uplinks levels are heavily revised variations of levels cut during Half-Lifes development phase, and are not present in the end version of the full game.
===Name===
The titles of Half-Life and its expansion packs are all named after scientific terms. Half-Life itself is a reference to the half-life of a quantity (such as a radioactive material), the amount of time required for the quantity to decay to half of its initial mass. The Greek letter lambda, which features prominently on the game's packaging and story, represents the related decay constant, as well as the Lambda Complex featured in the game. Opposing Force, while it could be named because the player assumes the role of one of the enemies in the original game, is also a reference to Newton's third law of motion, while Blue Shift refers to the blue shifting of the frequency of radiation caused by the Doppler effect or special relativity, in a similar parallel reference to the name of the work shift your character takes (as stated in the manual included with the retail version of the game). In Half-Life: Decay, the title again references the half-life equation with the lambda symbol being the decay constant. It has also been speculated that the Lambda symbol was chosen as it somewhat resembles a very simple picture of an arm holding a crowbar, the first weapon acquired by Gordon Freeman, and a weapon for which the Half Life series is famous.
===Ports===
Half-Life was ported to the PlayStation 2 by Gearbox Software and released in 2001. This version of the game had a significant overhaul in terms of both character models, weapons, and more advanced and extended levels and general map geometry, incorporated from work on a planned Dreamcast version. Also added in is a head-to-head play and a co-op expansion called Half-Life: Decay that allowed players to play as the two female scientists Dr Cross and Dr Green at Black Mesa. Another interesting feature allowed players to use a USB mouse and keyboard, a feature previously unmatched on the platform.
Versions for the Dreamcast and Mac OS were essentially completed, but never commercially released. Gearbox Software was slated to release a port to the Dreamcast under contract by Valve and their then publisher Sierra On-Line near the end of 2000. At the ECTS 2000, a build of the game was playable on the publisher's stand, and developers Randy Pitchford and Brian Martel were in attendance to show it off and give interviews to the press. The Dreamcast version revamped the graphics of the game with double the polygon count of the original models. Like Opposing Force for the PC and Decay for the PS2, the Dreamcast version was set to have its own exclusive expansion, Blue Shift. However, despite only weeks from release, it was cancelled; Sierra announced this "due to changing market conditions" onset by third-party abandonment of the Dreamcast and ceased production of the console itself. The Dreamcast edition was eventually leaked onto the internet.
That year Sierra On-Line showed its PlayStation 2 port at E3 2001. This version was released in North America in late October of the same year, followed by a European release just a month later. Around the same time, Half-Life: Blue Shift, which was intended to be the Dreamcast-exclusive side story, was eventually released on Windows as the second Half-life Expansion Pack. It featured the "High Definition Pack", upgraded models originally in the Dreamcast version, which overhauled the graphics of the original Half-Life and Opposing Force as well.
==Expansions==
Two expansion packs by outside developer Gearbox Software have been released for the PC version: Half-Life: Opposing Force (1999) and Half-Life: Blue Shift (2001). The former returns the player to Black Mesa during the events of Half-Life's storyline, but this time from the perspective of Adrian Shephard, one of the Marines in the Hazardous Environment Combat Unit sent to cover up evidence of the incident. It introduced several new weapons, new non-player characters, both friendly and hostile and new, previously unseen areas of the facility. The expansion is shorter than Half-Life, having 11 chapters to the original's 19.
Blue Shift returns the player to Half-Life's Black Mesa timeline once more, this time as Barney Calhoun, one of the facility's security guards. The expansion was originally developed as a bonus mission for the canceled Dreamcast version. Blue Shift came with the High Definition Pack, that gave the player the option to update the look of Half-Life, Opposing Force, and the new Blue Shift content. Blue Shift had relatively little new content compared to Opposing Force: aside from a few variations on existing models, all content was already present in the original Half-Life.
Half-Life: Decay was another expansion by Gearbox, released only as an extra with the PlayStation 2 version of Half-Life. The add-on featured cooperative gameplay in which two players could solve puzzles or fight against the many foes in the Half-Life universe.
In 2000, a compilation pack titled the Half-Life: Platinum Pack was released, including (with their respective manuals) Half-Life, Counter-Strike, Team Fortress Classic, and Half-Life: Opposing Force. In 2002, the pack was re-released under the new titles Half-Life Platinum Collection and Half-Life: Generation. These new iterations also included the Half-Life: Blue Shift expansion pack. In 2005, Half-Life 1: Anthology was released, containing Steam-only versions of the following games on a single DVD: Half-Life, Half-Life: Opposing Force, Half-Life: Blue Shift, and Team Fortress Classic.
==Reception==
Half-Life's public reception was overwhelmingly positive in terms of reviews, acclaim and sales. As of November 16, 2004, eight million copies of the game had been sold, while 9.3 million copies had been sold by 2008. The game has won over 50 Game of the Year awards.
Half-Life was critically acclaimed, earning an overall score of 96% on review collection website Metacritic. Computer Gaming World's Jeff Green said that the game "is not just one of the best games of the year. It's one of the best games of any year, an instant classic that is miles better than any of its immediate competition, and - in its single-player form - is the best shooter since the original Doom". IGN described it as "a tour de force in game design, the definitive single player game in a first person shooter". IGN has also respected the game as one of the most influential video games. GameSpot claimed that it was the "closest thing to a revolutionary step the genre has ever taken". GameSpot inducted Half-Life into their "Greatest Games of All Time" list in May 2007. In 2004, GameSpy held a Title Fight, in which readers voted on what they thought was the "greatest game of all time", and Half-Life was the overall winner of the survey. In the November 1999, October 2001, and April 2005 issues of PC Gamer, Half-Life was named "Best Game of All Time"/"Best PC Game Ever". GamesRadar also placed it in its list of 100 best games of all time. The popularity of the Half-Life series has led way to an array of side products and collectibles. Valve offers Half-Life-related products such as a plush vortigaunt, plush headcrab, posters, clothing, and mousepads.
The immersive gaming experience and interactive environment was cited by several reviewers as being revolutionary. Allgame said "It isn't everyday that you come across a game that totally revolutionizes an entire genre, but Half-Life has done just that". Hot Games commented on the realism of the game, and how the environment "all adds up to a totally immersive gaming experience that makes everything else look quite shoddy in comparison". Gamers Depot found the game engaging, stating that they have "yet to play a more immersive game period".
Despite the praise that the game has received, there have also been some complaints. The Electric Playground said that Half-Life was an "immersive and engaging entertainment experience", but said that this only lasted for the first half of the game, explaining that the game "peaked too soon".[76]
Guinness World Records awarded Half-Life with the world record for "Best-Selling First-Person Shooter of All Time (PC)" in the Guinness World Records: Gamer's Edition 2008.
A short film based upon Half-Life entitled Half-Life: Uplink, was developed by Cruise Control, a British marketing agency, and was 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 plot of the film was that a journalist infiltrates the Black Mesa Research Facility, trying to discover what has happened there.
