Half-Life Version 1.0

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. Compared to most first-person shooters of the time, on which 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. 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. 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.

The game's plot was originally inspired by the video games Doom, Quake (both PC games produced by id Software), and Resident Evil (published by Capcom), Stephen King's short story/novella The Mist, and an episode of The Outer Limits called "The Borderland". It was later developed by Valve's in-house writer and author, Marc Laidlaw, who wrote the books Dad's Nuke and The 37th Mandala. 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 (later referred to as the "Black Mesa incident") 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. Meanwhile Gordon goes through underground water channels as aliens pick off the remaining Marines until  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. Freeman 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 Freeman 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 G-Man's offer find themselves unarmed and surrounded by hordes of hostile creatures, as G-man says, "Well, it looks like we won't be working together. No regrets, Mr. Freeman."
