The excess between HL1 and HL2 is close to 20 years in the making.
1. The Fall of Civilization
After the events of Black Mesa, the Xen creatures continued to Manjen, rapidly expanding throughout the world and bringing chaos to humanity.
What really brought down human civilization was not the Xen creatures, but an interstellar alliance from other dimensions, the Combine. for some reason, the Combine discovered Earth and began planning an attack on it, preparing to colonize it and reduce humans to slaves. After careful preparations by the Combine, a great war breaks out.
Combine launched an attack on Earth, and after the war lasted only seven hours, humanity suffered a crushing defeat, and Brin advised humanity to surrender as soon as possible to prevent the risk of extinction. As a result, the Combine army (Combine's army) took over Earth in just 7 hours. Bryn became a puppet of the Combine, and was responsible for "managing" the planet.
Where there's oppression, there's resistance, and humans don't take slavery from another species lightly. The human race has organized itself into a resistance force to fight against the United Army, and the scientists who survived the Black Mesa incident, such as Eli and Kleiner, are the leading force of the resistance force. The Vortigauns are also dissatisfied with the rule of the United Army, and as rational beings, they have allied themselves with the human race to **** together against the tyranny of the United Army.
2. Combine's Rule
After taking control of Earth, the Combine began a series of colonization measures.
They began by renaming the human cities as City 1, City 2 ...... During the HL2 period, City 17 was established as the capital city, where the Combine's home base was located. In order to centralize the human survival strongholds, the Combined Army placed defenses around the major cities to prevent Xen creatures from invading the cities, and the outside world was left to flood with Xen creatures, so that most people actively chose to live in the cities, and the outside world became a space for the Xen creatures and the Resistance.
The United Army also set up a "Reproductive Inhibition Force Field", which prevents humans from reproducing and deprives them of the right to reproduce, so that they can slowly become extinct; they added a special substance into the drinking water of humans, so that their memories will gradually fade away, which is favorable for them to comply with the United Army; and at the same time, the human race's place of residence has to be decided by the United Army, and they are constantly moved back and forth. , being constantly moved back and forth and unable to settle down; those who resist the JSA are likely to be transformed into ghosts by the JSA after being arrested and serve the JSA; Brin instills the idea of obedience in humans through various media ...... In order to maximize the absorption of human members, the JSA has formed a police organization- the -In order to maximize the absorption of human members, the United Army formed a police organization, the National Guard, which was composed of human "traitors", and the participants could get good food to satisfy their sexual needs, so that a large number of human beings joined them to serve the United Army. The National Guard became an effective means of terrorizing the Union Army.
The Combine also modified headhunting crabs for use in purging the resistance. They prevented the parasitized zombies from eating, and when the host died, the headcrabs could detach and find a new host. When the headhunter shells are poured into the resistance's gathering place, they can turn all the locals into zombies or be killed by the zombies. The zombies are unable to eat and will slowly starve to death.
The army of the United Army is also known as the armored core, and there are many categories of armored core troops, so I won't go into detail here.
(IV) HL2
1. Return of the Heroes
Gman awakens Gordon once again, allowing Gordon to save the human civilization that has been trampled by Combine.
Gordon is sent to the train station in City 17, where he meets his former friend Barney from Black Mesa - now working undercover as a Resistance agent for the National Guard. Barney tells Gordon to go to Kleiner's lab. On the way, a Union search is underway in Gordon's neighborhood, and it is Alex, Eli's daughter, who saves Gordon. This brings the four of them together, Kleiner, Alix, Barney & Gordon, where Gordon gets his new suit - a HEV V (it's Roman numeral 5, not V) type suit improved by Kleiner. It happened to be the same day that Kleiner and Alex finished assembling the time transporter, and they decided to use it to send Alex and Gordon to Eli's lab; as a result, while teleporting Gordon, the transporter malfunctioned, the Combine discovered Gordon, and Gordon had to walk down the canal on foot to Eli's lab now.
Immediately after the Combine discovered Gordon, a large number of troops were dispatched, and the entire Citadel was placed under martial law. Because Gordon was seen along the railroad, almost all of the city's National Guard was sent to the railroad and the canal, ready to catch Gordon at a moment's notice, and many of the Resistance's underground stations here were cleared by the Combine while they had the chance.
The National Guard didn't manage to stop Gordon, and instead, were hit hard. Gordon, with the help of the Resistance, gets a steamboat. Gordon drove the steamboat, passed several barriers set up by the Combine, and finally arrived at Black Mountain Base East, Eli's laboratory nestled near the old waterworks. Here he meets Eli, Alex & Mossman.
In Black Mesa East, Gordon acquired the Gravity Gun. Just as Gordon was practicing using the gravity gun, the Combine launched a surprise attack on the area, and because the tunnels were blocked, Gordon had to travel alone to Levenholm, a mine that had been taken over by zombies. With the help of the local Father Gregory, Gordon escapes Levenholm and makes contact with the Resistance outside.
2. The Resistance
Gordon, who emerged from Levenholm, helped the Resistance forces stationed at the docks to start a firefight with the regular forces (the Combine had sent out regular forces at this point because of the ongoing seriousness of the situation). With the help of the Resistance, he used the radio to talk to Alex, and De knows that Eli has been arrested and is being held in the large prison, the Nova Mines. Alex suggests that Gordon take the beach road to reach the Nova Mines, and Alex enters herself using a Union Army train, and the two agree to meet in the Nova Mines.
Gordon drove the scout car provided by the Resistance across the beach and onto Highway 17. The Union regulars set up a number of checkpoints along the road to intercept Gordon, but all failed.
Gordon eventually reached Lighthouse Station, where he engaged in a defensive battle, and then reached the Resistance stronghold on the outskirts of the Nova Mines, where a Vortigaun helped Gordon obtain a pheromone capsule from inside an Ant-Lion guard, teaching Gordon how to use it. Gordon used the pheromone protection to shut down the Ant-Lion restrictors on the outskirts of the Nova Mines, allowing the Ant-Lions to enter the Nova Mines through the underground, causing chaos, and the Combine confirmed the operation as Freeman's work through aerial reconnaissance. The Combine sent in additional reinforcements and even deployed super troops, all of which failed to stop the Ant-Lions. Gordon took advantage of the chaos and infiltrated the prison to turn with Alex. They found Eli, and also discovered that Mossman was a traitor, and that the search of Black Mountain East was Mossman's intelligence for the Combine. Alex and Gordon plan to escape using the Combine's time teleporter, only for Mossman to secretly use it to teleport Eli and himself away. With the Union Army's army already approaching, Alex and Gordon have no choice but to re-open the teleporter and escape to Kleiner's lab.
By the time they got to Kleiner, a week had passed, though they couldn't feel it themselves.
In that week, the Resistance had started an uprising to save Eli, who had moved to the Citadel, and City 17 was already in the midst of a war, with the Resistance lunging at the Citadel as hard as they could. Alex and Gordon join the fight. During the alleyway battle, Alex is unfortunately arrested.
Gordon first crosses several blocks to meet up with Barney, then helps Barney by turning off the suppression equipment in the Combine's armored core building, allowing more Resistance troops to pass through the blocks heading to the castle, and finally, Gordon, with the help of Dog, enters the castle.
3. The Death of Brynn
Shortly after Gordon enters the castle, he is discovered by the Combine, whose weapons confiscation system confiscates all of Gordon's weapons, but the gravity gun is transformed into a more powerful weapon. Using the new gravity gun, Gordon rampages through the city and eventually reaches a pod relay station. Freeman realizes that it's going to be really hard to find Brynn on foot in this huge castle, and if he wants to take care of Brynn before Brynn executes Eli and Alex, the only way to do it is to turn himself into a prisoner and have Brynn voluntarily take him to his office and then figure out what to do. Even though it was dangerous and there were many variables, it was the only way to do it at the moment. So he resolutely chose to enter the pod and was found by the Combine to be taken to Brin's office.
Here, Gordon met Brynn, Mossman, and Eli and Alex, who were being held in the pod, and Brynn was going to send Alex and Eli through the portal to the world of the Combine, and it was at this point that Mossman betrayed Brynn due to his feelings for Eli, and Brynn panicked, and accidentally used his gravity gun to shoot down the pod that held Gordon and the others, but he didn't realize that the gravity gun had so much power that it actually destroyed the pod, there was nothing he could do but drop the gravity gun and escape, he planned to use the portal to escape to the Union side.
Alex and Gordon went after Brynn, and Gordon used the gravity gun to destroy the dark energy reactor at the top of the castle, and the top of the castle exploded, and Brynn's teleportation platform lost traction, and fell to his death from the top of the castle. Just moments after the big explosion, time freezes and the gman reappears, makes a brief comment to Gordon and disappears.
(VI) EP1 & EP2
1. Destroying the Castle (EP1)
At the beginning of EP1, when the castle explodes and the gman is about to "freeze" Gordon again for later use, the Vortigaunts accidentally enter the space between them and "convince" Gordon to "freeze" him. The Vortigaunts accidentally enter the space between them and "convince" Gordon to turn his back on the gman, and then, in frozen time, rescue Alex and Gordon from the Big Bang. (Since the development company didn't intend to develop the aftermath of the heist aka EP1 when they developed HL2, there's a small error in plot articulation here) When Gordon awakens, he's dug out of the rubble by Dog and is given the gravity gun, reuniting with Alex again (and Alex and Gordon have a nice hug~ ).
Between HL2 and EP1, the top of the castle had exploded and the entire castle was cut off from the top half, Eli and Mosmanli escaped the castle using Dr. Breen's life pod, then Mosman took a helicopter to the Arctic Circle (the purpose of this trip is not revealed in the game), and Eli and Kleiner escaped to Magnuson's research base in the White Forest, far away from C17. They discover that the Citadel will be exploding even more violently shortly, a nuclear explosion that will destroy the entire C17 metropolitan area, and, to make matters even more problematic, the Coalition's energy device, the Core, in the bottom section of the Citadel is energizing the explosion in order to accelerate it, and at the same time the Coalition is beginning to copying massive amounts of data in preparation for transmitting it to the U.A.E.'s higher worlds when the Citadel explodes, and launching the U.A.E. agents in the Citadel. Kleiner therefore began to issue notices to the citizens of C17, informing them to evacuate quickly. However, as a result of the damage to the Citadel, the Combine's reproductive inhibitory force fields and certain unknown other inhibitory force fields and the Combine's portal technology, as well as the communications equipment that relied on this technology, were eliminated and largely destroyed. This means that after nearly two decades of tyranny, humanity finally has the opportunity to reproduce itself and rebel against the Combine with greater power!
Alex and Gordon made contact with Kleiner and the others, and after obtaining the information, infiltrated the Citadel again, shutting down the core to gain more time to evacuate the citizens. And copied all of the data that the Combine was preparing to transmit, which led to the Combine sending a large number of troops to hunt down Alex and Gordon.
Alex and Gordon had hoped to use the underground train in the castle to escape directly out of the city without having to flee on foot like the other civilians. But halfway through, the tracks were damaged and the train was scrapped, meaning that not only did the two have to escape on foot, but they also had to return to the surface from an unknown depth underground first (stealing a chicken and not making it to the surface). So, the two escaped into the underground parking lot of C17, which is already controlled by zombies, and, due to Gordon's destruction during HL2, the Union's defenses around C17 have collapsed, and a large number of ant lions have entered C17 as well as the underground parking lot of C17, adding to the difficulty of Alex and Gordon's escape.
However, the two of them manage to escape the parking lot, reach the surface, and turn with Barney and the others. They hope to evacuate more citizens. For their part, the Union Army has deployed a large number of troops in the neighborhoods around the hospital and train station to stop the Resistance's plans. Remaining members of the National Guard in the Union Army also joined in to stop Freeman.
The Combine's plan failed, and Alex and Gordon not only escaped C17 themselves, but also helped many other Resistance members and citizens escape, as did Barney. However, there were still many people within C17 who did not listen to Kleiner who stayed behind.
Just as Alex and Gordon were escaping C17 by train, the castle exploded. A huge portal formed over the castle and data was beamed out, and Combine agents were launched in all directions using airships.
2. Stop the invasion (EP2)
After the castle exploded, C17 was completely destroyed, and it can be said that the United Forces on Earth have been isolated, however, the data that was launched before the castle exploded caused the United Forces on Earth to make contact with the United Forces high-level worlds, and the ruins of the castle once again formed the beginnings of a giant super-portal, which, once formed, would allow the United Forces to launch another invasion war. Once the portal is formed, the United Army will be able to launch another invasion war.
The train Alex and Gordon were traveling on overturned in the explosion, but both survived. The two of them use the abandoned radio to contact the White Forest side, and then decide to go to the White Forest to give the copied data to Kleiner and the others, and then use the data to shut down the Combine's portal. For their part, the Combine side hasn't given up searching for them for a moment, and the remaining Combine forces around C17 have begun to assemble, ready to recapture their data.
On the way to the White Forest, Alex is wounded by a Combine predator and is rescued by a Vortigaun and taken to a Resistance stronghold in an underground pit. Gordon and a Verdigon infiltrated the depths of the Ant-Lion Cave, got an extract of Ant-Lion eggs, and then saved Alex's life. At this point, the gman broke into Freeman's world once again, forcing Gordon in a commanding tone to escort Alex safely to the White Forest, and then telling Alex to send a message to Eli: "Prepare for unexpected results."
Alex wakes up and, along with Gordon and a Verdigon, finds a car in the old chemical plant, which Alex and Gordon then use to set out on the road to the White Forest.
On the way, they sabotaged the life support system of a Combine agent's egg, and the Combine agent escaped, but attracted heavy Combine forces, which they defeated and arrived at a Resistance stronghold, where Resistance comrades helped them repair the car that had just been broken in the engagement.
After that, Alex and Gordon's car was also ambushed by the Union, but the Union were unsuccessful.
Eventually, Alex and Gordon arrive at the rocket base in the White Forest, when Silo 2 malfunctions, and Dr. Magnuson asks Freeman to fix it, not realizing that the cause of the malfunction is sabotage by the Union Army. The Combine forces discover the location of the rocket base and airlift troops from silo 2 to the interior of the base, Gordon arrives at the control room of silo 2 in time to close the door.
Eli, Alex, Kleiner and Gordon then deciphered the data brought back and saw that Mossman had discovered the Northern Lights research vessel, a relic of Aperture Technology, at the North Pole, and that Mossman's life or death was uncertain. Kleiner decides to utilize the power of Aperture Technology against the Combine, but Eli is adamantly against it. After Alex delivered GMAN's words to Eli, Eli nearly fainted and repeatedly warned Gordon that he must destroy the ship.
At this point, the Combine were preparing to use a force of three-legged mechs to destroy Magnuson's rockets, and Gordon, under Magnuson's tutelage, learned to use the Magnuson Device - a sticky bomb to deal with the three-legged mechs - and then Gordon wiped out the Combine's attacking force and saved Magnuson's rockets. Kleiner and the others packaged the data into the satellite in the rocket and launched it, and the Combine portal immediately collapsed.
Next, Alex and Gordon decide to take a helicopter to the Arctic Circle in search of Mossman, Eli is killed by a Combine agent on their way out, luckily Dog shows up and saves Alex and Gordon, but Alex loses her father ......

Attachment 2: Explanation of some doubts
The following is partly unconfirmed, and is only deduced or speculated for the sake of temporary plot articulation. If later V reveals content that conflicts with it, the V content will prevail.
1. Gordon Freeman. Who is Freeman?
First of all, from the outside we can see that he is a man (crap!!!) . Has a pair of green eyes and wears a pair of black-rimmed glasses. A dark brown beard, dark brown eyebrows, and dark brown and messy hair.
He's just an average guy. In fact, he's a very intelligent ordinary human being, a physicist.
In HL1 we learn that Freeman is 27 years old, unmarried and unattached. Born in the city of Seattle.
Just as Gordon graduates, Kleiner has made a big step forward in the top-secret program at the Black Mountain Institute, and is in desperate need of some assistants to do the rest of the work. Freeman was unquestionably chosen, and he agreed to work at the Black Mountain Institute. This is described in the main text section.
Because of the urgency of the experiments, he was rushed to the laboratory after a short period of refuge and experimental training before he had been entered into the retinal access authorization system.
There is no doubt that he is the protagonist of the HL series, a man of few words, a man of great responsibility, a man of firm stance, a man of clear right and wrong. With a red-painted crowbar in hand and wearing a HEV suit with λ characters written on it, he, Gordon. He is Gordon Freeman.
According to Half-life 2: Raising the Bar, Gordon Freeman's name pays homage to Freeman Dyson, a famous American physicist.
2. What's the deal with HEV suits?
HEV protection system, the English Hazardous EnVironment, developed by the λ team of the Black Mountain base, specifically for the use of the scientific staff of the Black Mountain base in hazardous environmental conditions, such as the Black Mountain exploration team for the Xen to do business.
In HL1, Gordon uses the HEV fourth generation suit.
HEV 4 is a highly sophisticated protective system with multiple functions. First of all, HEV can help the user to complete a variety of actions, such as long crouching, jumping, etc., HEV can help the user to effortlessly complete; second, HEV has a variety of systems can help protect or warn the user's safety, these systems include: power assisted mobility system, high-impact reactive armor system, atmospheric contamination sensors, vivisection monitoring system, ammunition level monitoring system, communication systems, defense weapon selection systems and automated medical systems.
The HEV 4 uses electrical power to provide armor protection, and these rechargeable units can be found throughout the Black Mesa base. the HEV 4 can also interface with the Black Mesa base's medical equipment to feed the HEV's medical system. the HEV 4 can also carry a weapon and assess its condition. The HEV 4 can also monitor the user's physiological condition and provide assistance at any time.
In HL2, Gordon uses the HEV 5, a protective system that Kleiner improved on the HEV 4 by adding a running aid and an underwater oxygen supply, and the HEV 5 can also be linked to the Combine's charging unit.
3. What is the Combine?
Combine, or Combined Forces, refers to a cosmic alliance, an interstellar organization. They set up colonies in various parts of the universe and reduce other races to slavery; the humans in HL2 are under their rule. The Combine specializes in transforming other species to serve the Combine for the Combine under the control of the Combine, such as the Combine soldiers and three-legged mechs in HL2, which are all creatures that have been transformed by them. In other words, the Combine is, in fact, a concentration of many species in one large group.
4. Who are the G-man?
All I can say to this question is, no comment. I don't want to discuss too much about this person. If you're curious, I can give you a few guesses from researchers. /forums/thread-54066-1-1.html
Please note when reading this: everything is a guess!
5. Are the Blackshirts really the army there?
We don't have enough information on this either. All we know is that their mission is to plant a nuclear bomb on the Black Mesa base and kill any creatures that try to stop them, including the military.
6. Where are the creatures from HL1?
Some of them are still on Earth, the headhunting crabs being a good example. Some of them went extinct on Earth because they couldn't adapt to the Earth's environment. (Officially, VAVLE says their absence does not mean they are all extinct or killed off by the Combine.)
