The G-Man

"You are man...he is not man...for you he waits...for you..." - Nihilanth

"Something' secret steers us both...we shall not name it."'' - Vortigaunt

"(Gordon Freeman) has proven to be a fine pawn for those who control him" - Wallace Breen

The G-Man, or simply G-Man, is a key yet mysterious and enigmatic character in the Half-Life series. He is known to display peculiar behavior and capabilities beyond that of a human and his identity and motives remain almost completely unexplained. He plays the role of an overseer and employer, watching over Gordon Freeman as the games progresses.

Overview
Physically, the G-Man appears to be a middle-aged Caucasian male with a tall and thin physique, pale skin, black hair shaped in a military-style crew cut, prominent widow's peak, and green eyes. Throughout the entire Half-Life series, he is seen dressed in a gray/blue suit and is always seen (except in Half-Life 2: Episode One) carrying a briefcase which, in the original Half-Life , sports the logo of the Black Mesa Research Facility. He speaks in a slow, raspy yet commanding manner, with a certain accentuated low-key moroseness to his tone, sometimes placing unusual stress on syllables, stressing the wrong parts of words, making unneeded pauses, such as "diffference" (Drags the 'f' on for too long and changes speed of speech half way through) and awkwardly changing the pitch of his voice, sometimes in the middle of a word. It is common for the G-Man to elongate "S" sounds (i.e."Limitlesssss potential").

This odd manner of speaking, bordering on the cryptic, along with his appearance, is very reminiscent of the behavior of the real life phenomenon that are referred to as the "Men in Black" in various reports. This allusion is almost definitely intentional. His manner of speech, with misplaced pauses and sudden rapid "jerks" forward, is also reminiscent of that of Findthee Swing, of Terry Pratchett's Night Watch, as well as Torgo from the cult B-movie "Manos" The Hands of Fate. It can also be associated with his apparent ability to travel through time in that he may not quite grasp the appropriate length of syllables due to the way he perceives time.

The G-Man exudes a calm, almost disinterested demeanor, particularly in the ruined and alien-infested Black Mesa Research Facility – in situations in which other humans panic and flee, the G-Man can be seen calmly straightening his tie or brushing his suit lapels with his hands. He is regularly seen throughout the Half-Life games, yet it is rare for the player to see more than a glimpse of him before he walks out of sight, often down corridors or into rooms that have no other exit or are a dead end, and mysteriously vanishes. The G-Man is capable of operating a very wide range of machinery and technology, ranging from cellular phones and sealed steel doors to nuclear weapons and teleporters. Some say that he may be related to Aperture Science because of these abilities.

"G-Man" is almost certainly not his actual title or name. He is never identified, referred to, or even acknowledged to exist by other characters in any of the games before Half-Life 2: Episode 2, despite being seen interacting with them. "G-man" is simply the name of the character's model in the original Half-Life, and Half-Life 2 (possibly a reference to the slang term G-Man, referring to an agent of the United States Government), as well as in documentaries featuring employees at Valve Software. The character is also referred to as "Gman" in the voice actor list in the credits of Half-Life 2. Furthermore, in the manual for Opposing Force, Shephard makes mention of him as a "G-man." Most players use the nickname "G-Man," or "Government man," since his actual name is still unknown. Prior to the release of Half-Life 2, many players speculated that he was the Administrator of Black Mesa, but the sequel makes it clear that this is actually a separate character, Doctor Wallace Breen.

The G-Man is seen talking to various people, and yet at times it seems that only the player is able to see him. However, when Freeman is searching Xen for the Nihilanth, it can be heard transmitting various telepathic messages to him, one of them is "You are man...he is not man...for you he waits, for you..." and "The truth...you can never know the truth...", indicating that the Nihilanth is aware of the G-Man's intentions. In the climax of Half-Life 2, Doctor Breen speaks to Gordon Freeman, saying that he has "proven himself a fine pawn for those who control him," and informing Freeman that his "contract is open to the highest bidder." Breen also says to Gordon they can speak without Alyx and Eli there, possibly saying he wants to talk to Gordon one on one about the G-Man and Gordon's "contract". These lines, and the slightly smug, knowing way in which they are delivered, suggest quite strongly that Breen is aware of the involvement of a higher power in Freeman's actions. Also, the Vortigaunts have several ambiguous lines that could possibly be references to the G-Man, and in the introduction to Episode One they are seen directly confronting him, and somehow freeing Gordon Freeman from his control. This would seem to suggest a great awareness of the G-Man on their part, presumably something of his mysterious nature and goals, and possibly two-faced, separate will. Additionally, during a sequence in Episode 2, the G-Man appears to Gordon only while the Vortigaunts in the area are distracted, implying that they would be able to detect his presence or attempts to communicate with Gordon if they were not involved in what they were doing. Likewise, near the end of Half-Life 2: Episode 2, Eli Vance alludes to "our mutual friend", almost certainly a reference to the G-Man, after Alyx Vance delivers the message the G-Man gave her to deliver to Eli earlier in the game.

Contents of briefcase and other possessions
With the exception of the opening sequence in Half-Life 2: Episode One, and another sequence in Half-Life 2: Episode Two the G-Man is always seen carrying a briefcase, and fans have often debated its contents. In the original Half-Life, using the "no-clipping" cheat (noclip), or with the aid of a model viewer, it is possible to see inside his case. However, it's often pointed out that because the contents of the briefcase can only be seen by cheating or using game development tools, it is likely that the player was never intended to see them and so these contents may constitute nothing more than an Easter egg. Note that this only applies in HL1, as the inside of his case in HL2 is blank. The contents of the case appear to be as follows:


 * 3 pencils
 * 2 scribbled sheets of paper
 * A 9mm handgun in a holster
 * An identity card
 * A portable computer

Note: The latter two are merged as one item, for some reason.

Also, in Opposing Force, the G-Man is seen for a moment talking on a cell phone.

Half-Life


The G-Man is first seen travelling in the opposite direction on the tram ride that serves as HL1's introduction sequence, but he somehow manages to arrive at Sector C before Freeman. Before the experiment begins, the G-Man can be seen arguing heatedly with a black scientist, probably Eli Vance himself, as he has mentioned in Half-Life 2: Episode Two that he protested against the risky experiment, that the G-Man directly delivered the Xen crystal to him, and after that he "should have aborted that damn test", in a locked, sound-proof room of Sector C. Following the catastrophic resonance cascade which commences the game's action through Black Mesa, the G-Man can be seen quietly observing the player in several out-of-reach areas as the game progresses. In several cases, the player arrives in rooms or locations where the G-Man was previously seen, even though the areas are often inaccessible to other characters, and personnel in the location do not seem to have noticed him.

After Gordon defeats the final boss in Half-Life, Nihilanth, the ruler of Xen, the G-Man brings the player to "safety" in an inexplicable, abstract sequence, appearing beside Gordon, having stripped him of his armaments and showing him various areas of Xen, notably an area showing HECU corpses, wrecked tanks, and fallen jet fighters. This is shown when the G-Man said that he and his superiors have Xen under control, ironically. Eventually the scene changes into what appears to be a tram (like the one from the beginning of the game) traveling through space at an incredible speed. The G-Man tells Gordon that he has been observing him very carefully and praises him on his actions in Xen, which is now in his "employers'" control. The G-Man then informs him that he has recommended Gordon's services to his "employers", and offers him a job. Canon states that Gordon takes the job, although the player is given a Hobson's choice; declining the offer results in the unarmed Freeman facing a horde of hostile aliens as the screen fades to black with the G-Man's final words; "No regrets, Mr. Freeman." However, in HL2 the G-Man talks about the "illusion of free choice," because, of course, if Gordon had declined the offer and died at the hands of the alien horde there would be no sequel.

The official Half-Life 2: Episode One website states that "In Half-Life, the G-Man made you."

Opposing Force
In the expansion pack Half-Life: Opposing Force, the G-Man plays a slightly more direct role in the story, alternately hindering and aiding the player, Corporal Adrian Shephard, as well as simply observing.

During the boot camp training sequence, the G-Man can be spotted at a window speaking to an officer, and occasionally glancing at the player. Since the drill instructor mentions that Shephard's training has been mysteriously accelerated, the implication is that the G-Man had an interest in Shephard before the Black Mesa incident, for reasons unknown.

At one point Shephard is trapped on a small walkway, with deadly corrosive/radioactive liquid rising steadily towards him. The G-Man opens a door allowing him to escape, saving his life. One level later, as Shephard attempts to evacuate Black Mesa with the rest of the marines, the G-Man closes a hangar door, forcing him to remain on the base. Later on, the G-Man is seen rearming the nuclear bomb that destroys Black Mesa, which Shephard had deactivated moments prior.

After Shephard defeats the Gene worm at the end of Opposing Force, the G-Man appears again. On this occasion, Shephard finds himself on board one of the HECU's Osprey aircraft, facing the G-Man. The G-Man informs Shephard that, contrary to his employer's original wishes, Shephard is to be spared, but detained. The G-Man says that he has been impressed by Shephard's ability to "adapt and survive against all odds" in the Black Mesa facility, and comments that these are traits which remind him of himself. As the G-Man delivers this closing monologue, the plane carries them away from Black Mesa, shortly before a nuclear blast flashes outside confirming its destruction. The aircraft's location then suddenly switches to the skies of Xen, then finally to an emptiness similar to that encountered by the Black Mesa tram at the end of Half-Life. The G-Man then leaves Shephard via a teleporter in the cockpit, and the screen fades to the closing titles.

Opposing Force is the only game in the series in which the G-Man can be attacked by the player. This is done by placing a satchel near the nuke and detonating it when you walk by the window. He is unaffected by it and has no scorchmarks or blood on him. Also, he can apparently move through tripwires without detonating them.

Blue Shift and Decay
In both Half-Life: Blue Shift and Half-Life: Decay, the main characters of each game, Barney Calhoun and Doctors Gina Cross and Colette Green, see the G-Man on one occasion near the beginning of each game, but he doesn't seem to notice any of them.

Half-Life 2
Half-Life 2 begins with Gordon being greeted at some point in the future by the G-Man, while seeing a dream-like montage of images such as the Black Mesa test chamber, and interior areas of the Citadel. In his speech, the G-Man hints that he put Gordon into stasis for his own safety, and that an opportunity has now arisen which will allow Freeman to begin his campaign against the Combine forces on Earth.

The G-Man continuously refers to Gordon Freeman as "Mister Freeman" throughout the introductory sequence, forgoing Gordon's proper title of doctor. However, during the ending sequence, he refers to Gordon as "Doctor Freeman".

The G-Man is briefly visible at various other points during the events of the game, including along the different vehicle sequences, but these are only from a great distance or as seen on video terminals until the game's finale. After an uphill battle in the cloud-penetrating Citadel skyscraper, Gordon causes critical damage to the structure's dark energy reactor, resulting in an explosion that might have caused his death &mdash; had the G-Man not seemingly stopped time in order to extract Gordon to safety to await further "employment offers" (while apparently leaving Freeman's companion, Alyx Vance to perish in the explosion). The game ends with travel through the same emptiness that was HL1's ending, and with the G-Man stepping through some sort of doorway portal, though not before fixing his tie. The G-Man, at this point, makes it clear that he will once again be placing Freeman in stasis while he entertains some "interesting offers" for Gordon's services, this time making no mention of his "employers," as he had in HL1. However, in Episode One, the G-Man's control over Gordon is taken by the Vortigaunts (see below), ending (either definitively or temporarily) his plans.

Before their final showdown, Doctor Breen asks Gordon, "Did you realize your contract was open to the highest bidder?". This is taken as a reference to the "contract" Gordon has with the G-Man, and many players speculate that it may mean the G-Man is a freelance agent.

Half-Life 2: Episode One


The G-Man is only seen once in Half-Life 2: Episode One. At the beginning of the game, which begins at the point when Half-Life 2 ends, the G-Man walks back into the black void that he left Gordon in and opens his mouth to say something, but then notices a purple glowing Vortigaunt to his left. He appears to be slightly amused at the sight, but then notices another on his right, and the smile drops from his face. As more and more Vortigaunts appear, he begins to look irritated, and then, as he looks toward Gordon, he realizes what's happening. Irritation changes to anger. As two more Vortigaunts stand on either side of Gordon and grab his arms, the G-Man straightens his tie more violently than before and responds to their chant with a single sentence: "We'll see... about that!" Gordon is then immediately teleported away and found by Dog in a pile of rubble just outside the Citadel.

This incident shows the Vortigaunts have the ability to enter the G-Man's realm. This is also the first time the player witnesses any hindrance in the G-Man's plan.

Half-Life 2: Episode Two
The G-Man is shown in a trailer standing over Alyx, commenting that someone is "not supposed to be here" and that they should "forget about all this." It is unclear whom he is addressing. It is thus far his only appearance in any Episode Two trailer. The dialogue is an edited form of an unused voice clip from Half-Life 2, and his lines are quite reminiscent of The Matrix.

The G-Man appears more frequently in this game, than the previous episode, but at fewer intervals, at about 1/3 of the way through the game, as Alyx is resurrected by the player and the Vortigaunts, G-Man is evidently addressing Gordon to "forget about all this", it is not entirely clear what he actually intends by this, and prior to the end of this cut-scene, the G-Man whispers to the unconscious Alyx, to "relay these words": "Prepare for unforeseen consequences". It is also notable that during this speech, G-Man always states exactly what he means quite clearly, whereas all of his others to date have been very cryptic, requiring a great deal of thought to decipher their meaning.

Later, when Alyx and Gordon have arrived at White Forest and reunite with Eli Vance, Alyx relays the G-Man's message with some difficulty, followed by a brief period of confusion. Eli sends her to get him some tea, and begins to talk to Gordon about their "mutual friend", who is most likely the G-Man. He remarks that the G-Man whispered the phrase "unforeseen consequences" to Eli back at Black Mesa right before Gordon entered the test chamber, and that it was the G-Man that brought in the crystal that caused the whole incident. Later, Eli states that the G-Man is almost certainly involved in the events that are beginning to unfold at the end of Episode 2, but is equally confused as to his ultimate goal. He also implies that the G-Man had saved Alyx at Black Mesa, confirming the G-Man's previous claim of having "plucked her" from danger that day in spite of unseen "naysayers". Eli is nearly going to share more information with Gordon before Alyx returns to the room, giving the player the impression that Eli knows a considerable amount about him. Unfortunately, he doesn't share what he knows before the ending of Episode 2, not even his name (referring twice to him as "our mutual friend" only).

Unforeseen Consequences is also the name of the third chapter of Half-Life, in which Gordon regains consciousness after the resonance cascade. This clearly symbolizes the power of G-Man's words, as this event marks the beginning of the Black Mesa Incident.

List of in-game appearances
The G-Man appears several times in each game, though often in out-of-the-way locations so it may be difficult for a first-time player to see him. It is almost universally impossible to go directly to where he is standing – before he has an opportunity to disappear from that place, at any rate. If fired upon in the few areas in which he could be, he is unharmed, and a ricocheting sound effect is heard. This list does not include intro and ending sequences in which he speaks to the player character directly.

Half-Life

 * Black Mesa Inbound (map: c0a0d): When the tram Gordon is riding pauses briefly, the G-Man can be seen standing with a scientist in another tram frozen on the track. Coincidentally, this same tram can be entered in Opposing Force, in its same spot, indicating that G-man and the scientist have left.
 * Anomalous Materials (map: c1a0): The G-Man can be seen standing in an inaccessible room arguing with a scientist, where incomprehensible murmurs can be heard from behind glass.
 * Unforeseen Consequences (map: c1a1b): In his first appearance following the resonance cascade, he can be seen watching Gordon from a catwalk. When Gordon arrives at the same spot, it is revealed that the G-Man disappeared from an apparent dead end. A hiding scientist does not seem to have seen him.
 * Office Complex (map: c1a2b): As Gordon battles his way out of the administrative suite, the G-Man can be seen behind a locked door watching Gordon. He straightens his tie, brushes his suit with his hand, and walks off along a balcony over a corpse-filled cafeteria.
 * We've Got Hostiles (map: c1a3d): Immediately before Gordon's first encounter with the marines, the G-Man is seen on a high catwalk. He apparently leaves in a direction heading towards the marines. However, when Gordon arrives in the same spot, the marines have only just arrived, whilst a nearby scientist does not mention having seen him.
 * Power Up (map: c2a1): When Gordon arrives at the terminus of the rail network, he sees the G-Man watching him from a control room. By the time Gordon gets there, though, the control room is boarded up from the outside, and a wounded security guard there indicates no sign of having seen him.
 * Apprehension (map: c2a3b): In a large room filled with industrial pistons, the G-Man can be seen at the far end of the room. He leaves in a direction which leads to several hostile aliens and soldiers. It is in fact possible to catch up with him here as seen in the "Half-Life done quick" video. He disappears before he turns the next corner. However, the G-Man won't disappear if the player approaches him and hits the "use" key. The G-Man will turn around and simply remain in the same position. At this point it is possible to hit him with the crowbar. Doing so will produce a hollow metal sound.
 * Lambda Core (map: c3a2c): In the deserted Lambda Complex, Gordon watches through a window into a deserted room filled with headcrabs. The G-Man, standing on a raised floor, briefly looks at Gordon before stepping into a glowing portal. This is the first time the player sees the G-Man using the glowing portals, and it may explain how the G-Man has been able to so quickly get around the complex and disappear (especially into the aforementioned dead ends) before the player was ever able to reach him. He uses another glowing portal during the final sequence of Opposing Force.

Half-Life: Uplink

 * Uplink (map: hldemo1): At the very end of the demo, Gordon arrives in a large room filled with computers. A Gargantua breaks in and begins killing the hiding personnel. As the monster wreaks havoc, the G-Man calmly watches from a corridor, straightens his tie, and as the Gargantua approaches Gordon, slowly strolls away.

Half-Life: Opposing Force

 * Boot Camp (map: ofboot1): As Shephard walks through the camp towards his training area, he sees the G-Man and an officer watching him through a window.
 * Welcome to Black Mesa (map: of1a1): In a relatively undamaged area of Black Mesa, Shephard sees the G-Man talking to a security guard before walking away. It seems that he is instructing the guard not to let Shepard pass through the door, though this may not be likely, as the retinal scanner to open it is damaged from the outside, for unknown reasons.
 * Welcome to Black Mesa (map: of1a3): In a puzzling scene, Shephard finds himself trapped in a room which is rapidly filling up with toxic waste. The G-Man can be seen through a window, opening a door which allows Shephard to escape after a moment of hesitation. Even though Shephard is only meters behind him, the G-Man is nowhere to be found in the next room, which is filled with toxic waste and aliens.
 * We're Pulling Out (map: of1a6): Shephard races towards a transport aircraft as the marines evacuate Black Mesa. As he is sprinting down a corridor towards the plane, the G-Man calmly appears at the end of the corridor and closes a heavy door, trapping Shephard inside. He brushes his suit and strolls away as the evacuation plane takes off.
 * Pit Worm's Nest (map: of4a4): Shephard is deposited into a large garbage compactor. The G-Man can be seen quietly observing him from an observation window. After a short time he opens the door leaving the compactor.
 * Foxtrot Uniform (map: of5a4): After a battle with Race X aliens, Shephard arrives at the damaged Black Mesa hydroelectric dam. Standing on the inaccessible (except through use of the barnacle gun, this may be considered a glitch) control tower is the G-Man, who finishes a conversation on a cell phone and steps into a portal, powered by flying balls of light.
 * The Package (map: of6a4): Shephard arrives in an underground car park and deactivates a nuclear bomb. After a security guard lets him through a locked door, Shephard sees the G-Man re-arming the bomb. If the player attempts to backtrack to the bomb in order to deactivate it again, he will discover that the previously open chainlink fence leading there is now locked, making it impossible.

Half-Life: Blue Shift

 * Insecurity (map: ba_maint): Travelling through a maintenance area before the resonance cascade, Barney Calhoun sees the G-Man riding a tram. He does not seem to notice Barney, and is not seen later in the game.

Half-Life: Decay

 * Dual Access (Mission 1): Riding up in a glass-walled elevator after participating in a security registration scan, Gina Cross and Colette Green can see the G-Man pass, riding downward in an adjacent elevator. As with Barney's encounter, the G-Man is not seen for the remainder of the game.

Half-Life 2

 * "A Red Letter Day" (map: d1_trainstation_05): If Gordon flips through the main monitor in Kleiner's Lab a few times, eventually it will come across the G-Man staring at the other side of a fence. G-Man walks away shortly thereafter.
 * Route Kanal (map: d1_canals_01): In a resistance member's boxcar, a TV temporarily shows the G-Man, with a Vortigaunt watching and supplying television power. The G-Man appears to be in the same "studio" where Dr. Breen delivers his televised messages to City 17, complete with the Combine's logo.
 * Water Hazard (map: d1_canals_06): He is seen standing on a pier in front of the headcrab infested Station 7. As Gordon approaches, he disappears inside.
 * Water Hazard (map: d1_canals_06): Vaguely seen in a large rectangular monitor that flickers his image along with other breencasts.
 * Water Hazard (map: d1_canals_12): Seen overlooking a ledge as Gordon's airboat passes under.
 * Water Hazard (map: d1_canals_13): Before Black Mesa East, the G-Man can be spotted on a concrete ledge near the gate controls. However, once Gordon turns a wheel to raise a gate blocking his progress, the G-Man is no where to be found. Coincidentally, there is a sign pointing to where G-Man stood which states "Observation".
 * "We Don't Go to Ravenholm" (map: d1_town_05): After leaving Ravenholm, he can barely be seen walking off into a tunnel behind a few train cars.
 * Highway 17 (map: d2_coast_03): Looking through the Combine binoculars at the second house the player comes to on Highway 17, Gordon can spot the G-Man conversing with Colonel Odessa Cubbage at New Little Odessa, when the player arrives at the base the G-Man is nowhere to be found.
 * Nova Prospekt (map: d2_prison_02): Seen walking up to and peering through a door window while adjusting his tie as Gordon flips through the monitors near the beginning of the prison.
 * Anticitizen One (map: d3_c17_02): This is the weirdest (and possibly scariest) sighting of all. In a ruined tenement building in City 17, an image of the G-Man standing in a wooden boat with a crow on his shoulder is seen briefly on a television along with some very discordant music. Strangely, the TV is unplugged, and if the player approaches the TV it will turn off. Interestingly, G-man seems to either adjust his tie or make a pledge to America, scripted during the shut-off sequence. A resistance member blowing up Shield Scanners outside, after being talked to a number of times, says, "I can't get this tune out of my head." then whistles a portion of the eerie music.
 * Anticitizen One (map: d3_c17_03): Similar to the giant rectangular monitor seen in the canals, the G-Man's image flickers on and off with Doctor Breen's, before the monitor is toppled by resistance members, who show no sign of seeing him.

Half-Life 2: Episode One

 * There are no G-Man sightings in Episode One apart from his appearance in the introductory scene. It is possible that this is because the events of Episode One are not part of the G-Man's plan, as suggested by the apparent Vortigaunt intervention in the opening sequence. He does not have his signature briefcase with him here.

Half-Life 2: Episode Two

 * This Vortal Coil When the Vortigaunts are healing Alyx Vance, the G-Man appear, and speaks to Gordon about how he saved Alyx from the Black Mesa Research Facility despite protest from unnamed "naysayers", sitting in a room evidently situated in Black Mesa, although the facility have been destroyed long ago by the G-Man himself. The large monitor behind him says "Black Mesa Research Facility", then flashes images of Alyx. He then states that he wants a "repayment" for saving Gordon's life in Half-Life, not stating what it is. Then, he instructed an unconscious Alyx to tell her father to "prepare for unforseen consequences", after that Alyx suddenly wakes.
 * Freeman Pontifex The G-Man can be seen watching Freeman for the first time since the Vortigaunt intervention in Episode One watching from a bridge as the player watches from the overlook. Then the G-man walks towards a gate and disappears behind a wall.  This was mentioned in the commentary of the episode.
 * Under the Radar On the ridge above the inn, get out your crossbow and look towards where your car gets stuck and you'll see the G-Man quickly walking into the inn. You must quickly sprint to the edge of the ridge or you will miss him.
 * Our Mutual Fiend The G-Man flickers ominously on the screen which previously showed Dr. Mossman's recording, right before Alyx relays the message to Eli. It should be noted that Alyx is watching the screen as the G-Man appears implying that it might be the G-Man's reminder to "relay this message".

Half Life 2 Beta
Traptown In the map E3_Town_04: as soon as you control Gordon again, look upward. You will see the roof of the building, but the windows under the top of the roof have someone to hide, so get onto the platform in front of you and then look at the windows again. You will see the G-man run from the windows and you can see him run of top of the roof.

Theories
Many theories exist as Valve has (and might not ever) released any blunt facts about him/it. Fans have created temporary theories about who he is to keep them happy. Some of the most popular are as follows.


 * G-ordon free-MAN was initially the most accepted and popular theory. The Gman is Gordons brother, dad, or own self from the future. This is likely as Gordon and the Gman have many physical similarities.


 * A Demon somehow spawned from the Vortigaunts. This is logical because the Vorts seem to have knowledge of the Gman's presence.


 * Deity. Either some kind of immortal being possibly in control of the Nihalanth and Combine through Freeman's adventures.


 * It's a game. The most shunned theory. YOU ARE THE GMAN and this life of Freeman's IS some kind of pseudo-reality. A half-life. There are some things that the Nihilanth says that may support this.

Keep in mind that although fun and learning are the primary goals of all Gman theories, serious injuries may occur from believing them to be true. Valve has confirmed none of these and are, currently, non-cannon.

Trivia

 * In the comment section of the "npc_gman.cpp" file of the Source SDK, Valve writes the following: "// Purpose: The G-Man, misunderstood servant of the people."


 * Half-Life 2: Raising the Bar reveals that G-Man's Half-Life 2 model is based on Frank Sheldon, an Alexander Technique practitioner. He was originally slated to be the model for Dr. Breen.


 * In Half Life, G-Man's briefcase sports a Black Mesa logo while Half Life 2 does not.


 * The term G-Man is an American slang term for Government Man.


 * Fans have created numerous explanations as to who or what the G-Man is. Some of these are: covert leader of the Combine, leader of the Black Ops (he uses the abandoned lab of Rosenberg to teleport around), a Vortigaunt demon, person granted reality powers in the Black Mesa, secret leader of humans, and even Gordon Freeman himself from the future (though this one in particular has been denied by Valve).
 * It should be noted that it seems odd if the G-Man were the leader of the Combine that he would allow Gordon to destabilize the Combine rule on Earth in Half-Life 2. However, less sinister villains have allowed such actions on the part of a protagonist, depending largely on the former's motives.**


 * During the "heart to heart" sequence of Episode 2, the G-Man can be seen sitting at a desk in what appears to be a large office with the Black Mesa logo behind him on the wall. This may indicate that G-Man may be connected to Black Mesa and possibly have a high ranking position with Black Mesa.
