Plot review
You are a first-class marine, well-trained and brave. Three years ago, you were tried for resisting your boss's order to shoot civilians. Your boss went to Pearl Harbor in a plaster cast, and you were sent to Mars, the headquarters of United Aerospace Corporation (UAC). UAC is a big star company with radioactive waste treatment plants on Mars, Phobos and Phobos. Your daily work is boring.
In the past four years, the military, the largest supplier of UAC, has been using the facilities of Phobos and Phobos to conduct various secret experiments, including space travel in different dimensions. So far, they have been able to build a space door between Phobos and Phobos to move things from one place to another. But recently, space doors have become extremely unstable. The military "volunteers" who entered the space gate either disappeared without a trace or went insane. At first, they were rude and violent, and finally they exploded and died. The experimenters had to be busy piecing together the bodies all day and sending them back to Earth. The latest military report claims that the research has only encountered some minor setbacks and everything is under control.
A few hours ago, Mars received intermittent messages from Phobos. "We request immediate support, some ghosts are coming out of the space door, and the computer system is completely out of control!" The rest is completely incoherent. Soon Phobos disappeared from the sky. In the future, we can't contact any more satellites.
You and your combat team, the only combat unit within 50 million miles, were rushed to Phobos. Your task is to guard the periphery of the base, while the other team members enter the base. In the next few hours, all kinds of sounds kept coming from your communicator: gunshots, combat instructions, screams, broken bones, and finally, there was silence. It seems that all your comrades have been killed.
Things don't look good. You cannot leave this planet. In addition, all heavy weapons were taken away by teammates, except a pistol. If we can find a plasma gun, even a shotgun, we can kill several enemies. No matter who slaughtered your comrade-in-arms, no matter what, you should leave a few bullet holes in its forehead. You put on your helmet and left the landing zone. I hope I can find better weapons somewhere in the space station.
Walking into the gate of the base, you heard an animal-like howl coming from the corridor in the distance. They have found you, there is no turning back ... production company: id software.

Plot review
Finally, it's a pair. After several days of hard fighting in space, you finally got home. You are a first-class soldier on earth, well-trained, brave and well-equipped. You were there when aliens invaded Mars. Fight and fight, you finally win, stop the invasion, save Mars, and become a war hero. Of course, the military didn't mention much. You are the only survivor.
But it's all over. You retired from the army and returned to earth. The noise stopped and the landing craft landed. You push open the hatch and look out. Damn, there's a fire outside. What happened? You hobbled along, clutching the gun. A large number of refugees are fleeing from the burning city. Someone suddenly exclaimed, you look intently, what is that? Someone is attacking the refugees. You rushed up and shot, knocking the man down. It looks like a human figure, but strangely, its fangs are exposed and covered in blood, just like zombies in horror movies. Oh, this nightmare is not over yet!
You know this is another time, just like on Mars. At first, the human body was occupied and became a carnivorous monster. Then the real horror came, and the monsters from outer space invaded. But this time it was on earth.
From Tokyo to Tubke, from Stockholm to scranton, monsters invaded the earth. Billions of people died. Many people have turned into flesh-eating monsters, but there are still some, and very few people are still alive and human. These wise men found a way to save mankind. They built a huge spaceship to send survivors into space, away from this deserted world.
Unfortunately, the only spaceport on earth was occupied by the devil. The devil installed an energy field that surrounded the entire spaceport, and no spacecraft could land or take off. It's time for you to do it. Talking is better than nothing. The remnants of the earth attacked the intruders in the space airport. If it succeeds, we can turn off the energy field and let the spacecraft take off, so maybe human beings will not become extinct. If you fail, it's all over and mankind will become history.
You and your teammates start attacking. Soon, the soldiers fell like wheat cutters. You can't see your teammates, but occasionally you can hear their screams when they die, and the sound of crossfire echoes in the depths of the space port.
There is something hissing in the metal passage ahead. They are cruel, and killing is their only purpose. In a sense, they are the best opponents. Only you ... and them broke into Longtan alone. Production company: id software

Plot review
Although all the senior officials of UAC died, and most of the junior employees, including the concierge, died, the company survived and is now under the strict control of the government. UAC continued its secret research on material transfer, and continued its experimental work under enhanced security measures.
The headquarters of UAC is located on a satellite of Jupiter, which is farther away from the earth, so that any accident will not bring trouble to the earth. The marines are stationed at the base, just in case.
Shortly after UAC opened the space door, visitors from hell launched their first attack. Suddenly, monsters with sharp teeth gushed out from the space door, salivating, waving claws and pouncing on people. But death greeted them. The US Space Marines are ready, and bullets are pouring at the monster. More monsters gather, hoping to overwhelm the guards by numbers. But the rabble is no match for the Marine Corps. The Marines set up a defensive line around the space gate and killed hundreds of monsters without hurting anyone.
The end of the attack was as sudden as the beginning. The last burning skeleton screamed and was hit by twenty shrapnel at the same time. The hall was silent except for the sound of blood dripping. The attack of hell failed again.
The research continues, bolder and more unscrupulous. The government generously awarded each marine a silver medal, and UAC also made a large donation to the Retired Soldiers Fund. The defensive position has been strengthened, and the Marine Corps is on the alert for the next invasion. All their attention is focused on the space door. But this time they were wrong. After the protagonist experienced the story of doom, doom and doom, the devil's trick in hell didn't stop there. A few months after the space gate incident, the annual spacecraft supplies arrived ahead of schedule. On the radar screen, the spaceship looks much bigger than normal. It comes from another direction. Strange, but not incredible. The radar operator casually reported the arrival of the spacecraft, and the employees came to the landing site to meet them. But the ship didn't dock. It circled for miles above the base. People look up at the spaceship and know that big things are not good.
The spaceship can't come from the earth. It is huge, several kilometers long, composed of bones, steel and muscles, full of corruption and death. This is a biochemical, mechanical and magical spaceship from the depths of hell. It travels through space to get revenge. The door as big as a football field opened, and the devils swooped down on the ground, covering the whole base with their convulsive bodies, and it was everywhere in the blink of an eye. The fortifications built by the Marine Corps in the direction of the space gate became useless. Monsters rush into sewers, snorkels, corridors and other places, tearing, destroying and devouring.
Once again, turn the survivors into zombie monsters, and the purpose of existence is to kill, kill, kill.
Only one person survived, and that is you, the commander of the Marine Corps. You happened not to be at the base when the disaster fell from the sky. You are thousands of miles away, crossing the desert on Jupiter's moon alone. Suddenly there was a wheezing sound behind you, and you turned like a whirlwind to face one of them. Their images often haunt your nightmares. Your skills have not become obsolete with age. You pull out your pistol and smash the little devil to pieces.
Hurry back to the base and you will know what happened at a glance. The demon ship is still suspended above the falling base. Your children, the incomparable soldiers you have carefully trained, are all dead. You weren't there when it happened. You should die with them.
Ancient Japanese samurai may choose to die with their comrades-in-arms, but you are not. You raised your pistol. You should avenge your comrades. If failure is a fair death, who can live forever? Death from the devil's fangs may be the worst way to die, but if it is inevitable, then at least you have to fight before you die.
After the demons of hell invaded the earth on a large scale, the United States took measures to prevent the invasion from happening again. The old UAC was reorganized under a brand-new management system (the former directors and shareholders died anyway, which saved a lot of trouble) and devoted itself to researching new technologies and equipment to resist re-invasion.
Although the invasion was repelled and the remaining demons were wiped out by the sweeping team, the power of hell is obviously still strong. Although both the Spider Monster and the Minotaur have been eliminated, who knows what other monsters are in the different space? People are waiting, observing and preparing.
The new UAC began to develop quantum accelerators, hoping to close the door of different space from a distance and stop the invasion forever. The purpose of this project seems reasonable. Of course, in order to master how to close the space door, scientists must first re-learn the space door technology. This technology was re-developed soon, perhaps too soon.
Soon, the eyes of different space monsters turned to this new research project. One day, a space door of the research center opened and monsters from hell swarmed in. But UAC scientists have mastered their skills, the first operation of quantum accelerometer is perfect, and the door of invading space is closed forever. When the space door was closed, a monster's body was half exposed and cut in half. Theoretically, the earth will never be attacked by hell again. At least, once this technology is fully applied.
The next day, seven space doors were opened everywhere in the base, and the monster legion launched a storm. The quantum accelerometer immediately began to close the space doors, and within an hour, six doors were closed. But hell corps is too strong. The marines fought to the death, but in the end they were defeated by the enemy's minions. Scientists, marines and bureaucrats were either slaughtered or turned into zombies.
Quantum accelerometer and its prototype are located in the depths of the degenerate research center. A demon guard guards them and controls the last gate of hell. The government is afraid that the quantum accelerometer will be destroyed or used by the devil against us, and orders all marines to go there no matter where they are at present.
You are about to leave the beach, a place only a few minutes away from the research center, when you get the order. When you reach the center, it is full of flashes, howls and prayers. There are bodies everywhere. It is obvious that the demon gatekeeper is doing something in it, and something terrible will happen soon.
You know, in an hour or two, a whole division of marines will attack this base with the support of artillery and air strikes. You know they are too late. It is too late. Planes will be shot down by monsters suspended in the air, cannons will be blown up by missiles and fireballs from hell, and soldiers who rush into the UAC building will be torn to pieces. In an hour or two, the demons in the research center will complete their evil rituals and prepare to control the world again.
Everything depends on you. You must enter the research center and stop the demon guard alone.
