Half-Life storyline



"They're waiting for you Gordon, in the Test Chamber."

- Black Mesa Scientist

This article describes the Half-Life storyline as it is played in-game; chapter by chapter.

Hazard Course (optional)


The Training Facility at Black Mesa houses the Hazard Course to help users of the HEV Suit hone their skills at jumping, crouching, and combinations of both - everything you're going to need to worm your way out of a facility that's crashing down at your heels as aliens appear in flashes of green light all around.

Scientists observe from windows on the side, marking your performance on clipboards. They congratulate you on doing well and you aim to impress. Towards the end, there is instruction on how to use the Long Jump Module, as well as instructions on how to interact with objects in the environment.

Trivia

 * In Opposing Force, the player can visit the Hazard Course at the duck-jump training room by using the Displacer Cannon in Xen, where Adrian Shephard first acquires it. The room appears to still be functioning, as the Hologram and success markers still function. A nearby Vortigaunt mistakes the Hologram for a real person, attacking it. It soon realizes that the Hologram is fake, and proceeds to attack the player.


 * In Half-Life: Decay, one of the chapters happens to be Hazardous Course, in which Doctors Colette Green and Gina Cross walk through the destroyed remains of the course. The Hologram in the course is Gina Cross, one of the main characters in Decay.

Black Mesa Inbound


As Gordon Freeman rides the tram to his underground lab at 8:47AM, little does he realize that it is the calm before the storm. The public announcement system announces the most recent news, making ironic comments about hazardous substances and urinalysis tests, as disturbingly large pools of radioactive waste pass by him. Doors clunk open and close again behind him as he goes slowly underground to the test chamber. From the windows, Gordon can see nuclear missiles ready for transport to launch sites, robots nearly crashing into the tram, and the intricate workings of the Black Mesa Research Facility revealing themselves as being fragile, and more often than not, broken. Bashing on the locked door, Barney Calhoun passes by as Gordon silently continues his trip.

At a robot crossing, the tram is stopped, and on the left, a mysterious man in a blue suit stares blankly past him. Eventually, the tram reaches its destination, and after stepping out onto the precarious catwalk, Gordon's day only just begins.

Trivia

 * This chapter features the only confirmed sighting of Barney Calhoun in Half-Life, affirmed by the beginning sequence to Half-Life: Blue Shift.
 * In the penultimate map of this chapter, it is possible to see a different version of the Sector C Test Labs entrance behind the door.

Anomalous Materials


Arriving at the Anomalous Materials Laboratory, his usual place of work, Gordon dons his HEV Suit and checks his locker, as per routine. Beginning his journey to the test chamber, he goes past the cafeteria, where two more grumpy scientists are sitting. Noticing the microwave on the right, Gordon spots a chance for a practical joke. Turning up the power, he steps away and waits. The casserole within explodes violently, and the scientist comes rushing over, disparaged at the state of his breakfast. Continuing down to the lab once more, Gordon finds himself face to face with the people conducting his test.

They inform him that they have a unique and large sample, and that they will be deviating from normal procedure to accommodate for this. Carrying on through more doors and past more scientists, he enters the chamber, and the large metal door closes behind him.

Following the normal procedure, he goes up the ladder to the control panel and presses the button to start the rotors on the excessively huge Anti-Mass Spectrometer suspended from the ceiling. Going back down, he waits for the sample to arrive in its cart. Rising up from below, the sample arrives at last. "Standard procedure for a non-standard specimen," they assure him from above. "Go ahead, Gordon." Taking the cart in hand, he pushes it nonchalantly into the beam.

All that happens next became something of a blur. Screaming from the scientists, telling him to stop, but drowning that out, the deafening sound of explosions, and flashes of green light that leave fading marks on his retina. Then black. All that can be heard is the sound of his heavy breathing. Another flash of green, and he's on a strange alien world. Just within the pool of green light around him, odd-looking bipedal lifeforms stare at him, confused about why he's there. More so, Gordon wonders where he could possibly be. Another flash of green and he's back in the destroyed test chamber, feeling considerably worse for wear after his entirely other worldly experience - but it's certainly not over yet.

Trivia

 * At the beginning of the chapter, behind the desk where the security guard is sitting, there is a red and green switch. If used, it will momentarily set off an alarm.


 * In the same room the security guard is sitting, there is a small set of machinery in the lower left corner. There is a red and a green button on the front of it. Upon pressing the use key on either of them (they are part of the same model), a laptop folds out on top of the set of machinery. The owner of the laptop, a scientist, sees this and scolds the player, saying he's "expecting a very important message" and closes the laptop and locks it preventing Gordon from using it.


 * Continually using the microwave oven located on the way to the locker room will cause it to explode. This "microwave casserole" incident is mentioned by Doctor Magnusson in Half-Life 2: Episode Two.


 * In Gordon Freeman's locker can be found several easter eggs: a baby's picture and the books The Orchid Eater and The 37th Mandela, written by the series' writer Marc Laidlaw. Other lockers bear the names of Valve employees, such as Marc Laidlaw, Kelly Bailey, Ted Backman, Chuck Jones, John Guthrie (which is open in Unforeseen Consequences and contains an American flag and ammo for the pistol), Ken Birdwell, etc.


 * In the test chamber, if the sample is pulled from the Spectrometer, one of the Vortigaunts teleporting in there won't teleport out; instead, he stands on the cart and attacks Gordon. He will be there after the map change, floating in the air, therefore it is not advised to remove the sample.


 * If, by using the 'impulse 101' cheat, you fire the Hivehand weapon into the pit of the Anti-Mass Spectrometer in the test chamber, it will cause the resonance cascade without having to activate the machine or push the specimen into place.

Unforeseen Consequences


As Gordon Freeman's efforts to reach the surface to get help in the aftermath of the Resonance Cascade just begin, more problems get in his way. The building starts falling apart in his face, and mysterious alien creatures materialize from thin air. Gordon is given his trademark crowbar, and more weapons and hazards entail.

After being told that all communication outside Black Mesa has been lost, Gordon is requested by his colleague Eli Vance to try to make it to the surface in order to acquire help. Black Mesa has received massive structural damage, and to make matters worse, aliens from Xen,the border world begin randomly teleporting all around them. Most are simply reacting naturally to their new surroundings, but even more hostile are the creatures Gordon saw earlier (known as Vortigaunts). Also, strangely, Gordon occasionally witnesses the man in the suit, the G-Man, watching him from out-of-reach places, always walking off before Gordon can get to him.

Since the tram is too damaged to work, Gordon must cross Sector B's Coolant Reserve Facility in order to find a way out.

Trivia

 * The blue and red button on the laptop (the one that is locked to prevent Gordon from using it) from Anomalous Materials is changed to be a large, white button.


 * The door leading to the monorail can be opened after the Resonance Cascade by destroying its monitor (or the controller). Through the door a scientist can be found, who will fall to his death. Ammo can also be found there.


 * The title alludes to the G-Man's words to Eli Vance prior to the Resonance Cascade, where he told him to "prepare for unforeseen consequences". As revealed by Eli to Gordon in Half-Life 2: Episode Two, the G-Man is where he got the alien sample from.


 * The original name of this chapter was: The Portal Device.

Office Complex


Minutes after the Resonance Cascade, Gordon reaches the office complex, where several scientists are barricaded into rooms, hiding from the rampant aliens in the complex. He hears rumors that the military have arrived to rescue the people trapped in the facility.

Trivia

 * The original name of this chapter was: The Office Warrens.

"We've Got Hostiles"


This chapter finds Gordon Freeman making good progress, passing through various storage and staging areas, continuing his hunt for a way to the surface. Gordon learns that the soldiers rumored to be coming on a rescue mission have already arrived. He attempts to join up with them, but walks into a room to witness a Marine killing a scientist. It is then that he discovers that the Hazardous Environment Combat Unit, which has taken control of Black Mesa, is not just killing the aliens, they are also killing everyone connected to the project, including himself.

When he eventually reaches the surface, Gordon finds himself in an area totally under the control of the military and, worse, in the middle of an artillery bombardment - taking cover, he is forced back into the underground complex. However, it is revealed that the surviving members of the Lambda Team (in the Lambda Complex at the other end of the facility) may be able to close the dimensional rift. Therefore, Gordon begins the journey across Black Mesa to reach them.

Trivia

 * The original name of this chapter was: The Security Complex.
 * In the beginning of the chapter, a scientist is seen screaming about opening the silo doors. You can crowbar him once, and he can run into the door to the office. In the office (where the zombie drags the guard into the air vent) you can press the button to open the silo door, and continue to Blast Pit, without needing to complete the entire level.

Blast Pit


Gordon Freeman enters an abandoned, largely sealed-off area of Black Mesa dating back to its earlier days as a missile complex, full of mothballed machinery and now used as a dumping ground for toxic waste from the rest of the facility, where the HECU soldiers have yet to get a good foothold because of the high concentration of aliens in the area. It is here that Gordon faces a deadly new foe, the Tentacle. However, after reactivating the fuel, power, and oxygen lines, Gordon is able to kill the Tentacle by using the rocket engine at the top of the silo that the Tentacles were inhabiting, and finds a way out through the meters-long dirt tunnel dug by the Tentacle.

Trivia

 * The old level name featured on Half-Life: Day One, given in the "titles.txt" file was: Screams and whispers.


 * The Scientist taken by the Tentacle can be saved; by running to the scientist and talking to him as soon he begins to run. The Scientist will talk without being taken by the tentacle. The tentacle will do it's scripted movement.


 * After killing the tentacles and going to the next map, if the player is to return back (by using noclip), then the tentacles will be present again as if they weren't killed.

Power Up


Trying to reach the surface once more, Gordon's progress is thwarted by a clash between a Gargantua and HECU soldiers in the Sector E Materials Transport. He then learns from a dying security guard that if he restores the generator, he can ride the monorail to the surface. Freeman enters the Houndeye-infested subterranean areas and activates the generator, restoring power to the vicinity. After activating more switches, he destroys the Gargantua patrolling the area by turning on the huge transformers supplying power to the tram line.

Hitching a ride, he smashes through a barricade of concrete blocks before continuing on his way.

Trivia

 * The old level name featured on Half-Life: Day One, given in the "titles.txt" file was: Footfall.

On A Rail


As Gordon Freeman rides a monorail in the Materials Transport section of Black Mesa, he learns from a security guard that he must ride to the High Altitude Launch Center to launch a satellite, which the Lambda Team can use to reverse the effects of the Resonance Cascade. He also discovers the HECU's true hatred for him, as well as larger reinforcements: sandbag bunkers with rapid-fire sniper rifles, mounted machine gun turrets (manual and automated), and even mounted rocket launchers. After going round in circles, it seems, for a while, he goes up several elevators and at last reaches the surface again. At the launch site, he sends the rocket up into orbit, and regretfully goes back below ground.

Apprehension


Continuing towards the surface, Gordon encounters a terrifying new aquatic creature, the Ichthyosaur, and acquires a deadly new weapon to fight it. After an underwater battle with the creature, he manages to escape and get back on his way.

After battling with the Black Ops, another "rescue" crew trying to kill even the marines, Freeman is captured by the HECU. They remove all of his weapons, and leave him for dead in a trash compactor. Thankfully, Freeman escapes once again, making his way back into the battle.

Trivia

 * The old level name featured on Half-Life: Day One, given in the "titles.txt" file was: Abandoned silo.

Residue Processing


After escaping from the trash compactor and getting back to the surface, Gordon stumbles towards a mostly abandoned part of the facility, meant for processing and disposing of waste and hazardous materials. Dodging and jumping through antiquated compaction machines, great vats of green waste, and slipping through furnaces, as well as riding on gravity-defying conveyor belts, Freeman escapes to a hidden part of the facility.

Trivia

 * The old level name featured on Half-Life: Day One, given in the "titles.txt" file was: Chutes and ladders.

Questionable Ethics


After escaping, Gordon eventually winds up in a secret part of the facility where he discovers that scientists had been "collecting" specimens from Xen long before this whole mess occurred. In it, Gordon Freeman continues to rearm himself against the HECU, and rejoins the battle against these enemies. Gordon also encounters the alien military units, the Alien Grunts, and he finds one of the most powerful weapons in the Half-Life universe, the Tau Cannon, after a security guard accidentally blows up himself, a scientist, and a wall by overcharging it. Soon, he heads outside to search for the Lambda Complex.

Surface Tension


After arming himself with advanced prototype weaponry, Gordon again reaches the surface. It has become a war zone. The Vortigaunts, along with Alien Grunts and Gargantuas, have begun making determined attacks against the Marines, and the tide of the battle is beginning to turn in favor of the aliens. The Marines call in reinforcements, but it isn't enough. Gordon must scale cliffs and navigate the bombed out buildings while avoiding both sides as the forces of Xen begin to dominate the battlefield. Finally, Gordon reaches relative safety underground.

Trivia

 * The original name of this chapter, Cliff Hanger, was used on E3 1998.


 * Like "Half-Life", "Blue Shift", "Opposing Force" and "Decay", "Surface Tension" is a scientific pun, referring to the properties of water which makes certain objects float above it.


 * A part of a map in this chapter was used to create the map Hunted in Team Fortress Classic.


 * The canyon scene was mirrored at the end of the Half-Life 2 chapter Sandtraps, the Headcrab in the last pipe being replaced by a Fast Zombie. The Apache scene is also mirrored at the end of Lost Coast.

"Forget About Freeman!"


In this chapter, the HECU determine that they're fighting a losing battle against the Xen aliens and, having continually failed to neutralize Freeman, abandon their mission and begin to evacuate the facility, calling in air strikes and heavy artillery to cover their retreat. Meanwhile, Gordon makes his way into an underground storage garage to avoid the bombardments, and eventually fights his way through scores of aliens and several groups of the decimated HECU forces before reaching the Lambda Complex.

The Marines begin to evacuate Black Mesa and air strikes begin. Gordon navigates underground water channels and tries to avoid scores of alien invaders as they pick off remaining Marine stragglers.

Trivia

 * The old level name featured on Half-Life: Day One, given in the "titles.txt" file was: "You're on your own".

Lambda Core


In this chapter, Gordon arrives at the Lambda Complex, where he believed the science team to be sheltering from the Xenians, only to find that the majority of the complex is now overrun by hostile creatures. He is informed that he must flood the reactor chambers in order to access the core, and that a team of scientists is waiting for him at the tip of the reactor. Gordon must then navigate through the Lambda Core, facing numerous assaults from the Xen forces (the primary enemy, now that the HECU has pulled out). In the end, he learns that a single large entity is hosting the invasion, and that he must teleport to Xen to stop it.

After much struggle, Gordon finally reaches the Lambda Complex, where he discovers that the Lambda Complex is where they developed the teleportation technology that allowed scientists to travel to Xen in the first place. The handful of surviving personnel, who have held themselves up in a small stronghold, inform Gordon that, unfortunately, the satellite he launched was not able to reverse the effects of the Resonance Cascade because an immensely powerful being on the other side is keeping the portal between the worlds open, and Gordon must kill it to prevent the Xen aliens from taking over completely. But before being teleported to Xen, Gordon gains access to several ammunition, health and HEV-charge caches, the Gluon Gun, and he is finally reunited with the Long Jump Module (not seen since the Hazard Course). After an attempted interception by Alien Controllers, the scientists activate the teleporter and Gordon is teleported to Xen.

Trivia

 * The scene near the end of the chapter with the scientist holding the shotgun was mirrored near the end of the Half-Life 2 chapter Entanglement, where Dr. Kleiner was holding a Shotgun as Alyx and Gordon arrived in the teleporter.


 * The Gluon Gun can be found earlier in the level guarded by a lonely scientist.
 * The old level name featured on Half-Life: Day One, given in the "titles.txt" file was: Down and out.

Xen


Gordon Freeman arrives in the borderworld, Xen.

On the strange borderworld, Gordon encounters many of the aliens that had been teleported into Black Mesa in their natural habitats, as well as the remains of HEV-wearing researchers that came before him.

Gonarch's Lair


Freeman is made to face one of the Nihilanth's most powerful minions: the Gonarch in her lair.

Interloper
Gordon's journey across Xen continues, but his supplies are running short, spent on destroying the Gonarch. He also comes across the Xen army's Alien Grunt cloning facility, where the army is created. It can be noted that the Vortigaunts in one of the factories are not hostile towards the player, and will ignore him unless attacked.

Nihilanth


In a vast cave, Gordon finally confronts the powerful and mysterious being that is holding the portal open. Gordon destroys the Nihilanth's shield, allowing him to destroy its vulnerable brain. As the creature dies, it floats toward the ceiling, and explodes in a giant green blast that overpowers Gordon's senses.

Endgame


When Gordon comes to, he is confronted by the G-Man. Both are transported to various locales around Xen, while the G-Man praises Gordon's actions in the borderworld (which he refers to as "a nasty piece of work"). He explains that his "employers", agreeing that Gordon has "limitless potential", have authorized him to offer Freeman a job. The final teleportation takes Gordon to the same tramcar that he rode on at the beginning of the game, but apparently flying through space at immense speed. Gordon accepts this offer by stepping though a portal, and, finding himself floating in nothingness, hears the G-Man's voice one last time: "Wisely done, Mr. Freeman, I will see you up ahead..." The story continues from this point in Half-Life 2.

Alternatively, the player may choose not to step into the portal in the final scene. This causes Gordon to be teleported into a giant cave facing rows of Alien Grunts and Manta Rays as the game ends with the G-Man's comment, "Well, it looks like we won't be working together. No regrets, Mr. Freeman." Gordon's appearance in Half-Life 2 suggests that this "bad ending" is not part of Half-Life canon. Although the Grunts don't seem to do anything, and the screen fades out before any action is made, it is assumed that Gordon is killed, due to the G-Man's comment about the second choice, saying that the alternative is "A battle that you have no chance of winning." Following this scene is a status report saying, "Subject: Freeman; Status: Observation terminated; Post Mortem: Subject declined offer of employment."

Trivia

 * The chapter name "Endgame" is given in the "titles.txt" file and in Half-Life save and load dialogs.
