The history of the universe Dead Space (Dead Space)

Ah, the toy was already a full decade.
After so many years, I decided to dive into this universe and, in the end, could not help but create a topic for discussion. For those who still remembers this work, which we will never see... a pity.
Decided to pour what was to become aware of all that happened in the series.
Considered - Dead Space: Extraction, Dead Space: Downfall, Dead Space: Aftermath, Dead Space 1 & 2(Games).

That is what started all this trouble - the obelisk (or marker) is a trivial biological, chemical, and mental alien weapons, what all the factors simultaneously.
Biological threat - infection at the level of molecules propagating from the megalith obelisk, infects the cells of the tissue that is not capable of division - dead bodies, isolation of konechnosti, blood, cells, stool and so on, forcing these molecules to mutate. Distributed in air, in vacuum, in any area where you might move.
From large concentrations of cells, with different groups of tissues such as internal organs, skeleton and muscles are formed the bodies ability to move, see hear, that is, zombies who have one goal - to reproduce. But the reproduction there is only one way - the death of all living things.
If this process does not stop, with a constant flow of newly elected zombarey who were previously normal people or animals, cells, which are now the corpse are not able to exist with such physical congestion collapse, thereby all these zombari fall apart after a day or two or three, but dry and rough fabric continues to recombine, and of the huge number of corpses are all the more deadly for its size and the characteristics of monsters.
Chemical threat - of what remains after a massacre, if biological material is not enough for complex mutations - for example, no stomach, intestines, lungs and other biodegradable waste - these bio items are accumulated, and then disintegrate into tissue framework of the future version of the mutation. Lumps lungs and stomach are organized filters, releasing a putrid gas on a large scale, killing any living organism within a few tens of minutes. After that, the process is repeated on the way a biological attack.
Mental threat - induced marker of infection popadaya in the respiratory tract and the blood, causes hallucinations and delusions from living people. Since these particles have a total Biofon - there is a poisoning of the brain and other organs, causing infection carrier suffer all possible psychological illness. The more time a person is under the influence of this influence, the more likely he will go crazy and kill yourself, but because it causes hallucinations, aggression and amnesia, the subject will try to destroy as many living beings around him. If there is not close -
he'll kill himself.

Now why all this:
Assuming that the origins of the whole idea of monsters from the game series Dead Space - taken on the basis of the creations of Ridley Scott with his Alien. Like Ridley alien organism that wants to destroy all people born in the bodies of the people themselves, after infection. Here the principle is the same, but on a planetary scale.
The whole idea of the writers who invented this nonsense, is that 60 million years ago, our earth was one of these obelisks. Real, created by aliens for breeding, consisting of non-existent on earth material and is capable of destroying all life on the planet, fell to us in the form of a meteorite. But because his fall had at that time when on earth there was only primitive life forms or dinosaurs, this weapon has spent all of its functions. Killing via killing all kinds of live fauna of our planet, such as Dino, and thus, ending almost all of its biological attack, this weapon launched our planet's cycle of evolution. Well, over time, the functioning of this weapon has stopped and, in the end, when Reformirovanie over a million years - it was lost for many tens of kilometers under the sea level. And only in the 23rd century is already fully evolved humanity was able to detect it, a meaningless piece of stone with nothing but incomprehensible to anyone exuding waves. Well, people went and did what you want the killers from space in similar situations - copied its chemical structure, and recreated from similar materials. So the process was started again. As the copy was not necessary number of genes for normal operation - that thing was attacking people mentally, reducing people crazy, causing them to kill each other. Thus, in just a few years of study, and fed corpses - the new model was a perfect copy of the original. And, of course, started to work in full force: the madness and chaos, mountains of corpses. In the end, one of the scientists, as You all know, Mr. Altman,
decided to tell to humanity, but it is natural, cover. Leaked information all shocked, not surprisingly. As in our real world, even though it was hundreds of years ago - such nonsense that defies reasonable explanation, especially given that information to the masses came only fragments, as whole took over and created a new religion. The same care about Altman of certain individuals has only exacerbated the situation around the newly-believers. Even to the end and it is not clear whether he was the victim of an experiment or system, but to the saints believed it did. However, because of his labors as he was able to discredit the entire, existing at the time, science took a everything for God's intent, which is not surprising, given how the marker affects living beings. But, as people who ran the experiment, knowing the true causes of chaos, and the real cause of the emergence of a new life forms - zombar, could not bear the idea of his death in such a painful and imminent option, took a relatively reasonable solution. People created the obelisk was isolated and sent with a battalion of scientists to a planet called Aegis 7. And, of course, nobody returned from there.
Insert:
(The plot of Dead Space 3 - the same thing happened on Tau Valantis. I while it is difficult to combine in the mind of these parts of the story that don't mention each other. The only connection between the first and third games of the series, is that in the first obelisk called the marker 3A, and the Tau Valantis is already talking about it. XS in short).
200 years later, in a closed state of the Earth planet, comes a fleet of colonists to organize production resources. After three years of work, during which the colonists had been established that minerals from this planetary piece of the mountain can be retrieved in the next few years, ensuring the existence of many decaying planetary stations, was discovered the obelisk created by people on earth 200 years ago. Was called the most important slim the industry - the USG Ishimura, where most of the crew and staff were selected on the basis of - believe - fly. After extraction novosibenergo marker naturally began that for which it was created is a weapon. But I woke up something else. It seems that what is left from all those scientists sent to study the marker. Because after their mission has stopped responding - the planet and was closed. Perhaps it is because of their flesh and blood and appeared the same - the hive Mind.
