Halo Universe



-Chris Carney on Halo 3 Legendary Edition: 7 Steps To World Domination

Set approximately 544 years in the future, the Halo Universe has humankind colonizing the galaxy only to stumble upon a hostile alliance of aliens known as the Covenant, who, motivated by the power of the Prophets and the promises of paradise-after-death, are bent on humanity's destruction. It is this universe where the Halo video game series: Halo: Combat Evolved, Halo 2, Halo 3 and the game Halo Wars take place. In addition to the games a number of Halo's books have been released; these books involve Master Chief and many other characters. The books expand into the Halo Universe timeline before Halo: Combat Evolved, as well as running concurrently with the games' timeline.

Primary Factions
In the Halo Universe, there are many players, factions, political groups, races, and species. The main factions are as follows:

United Nations Space Command


542 years into the future, most of humanity is ruled by the United Nations Space Command (UNSC). As the most of the canon material from the Halo Universe is from the ongoing war we see the future mainly through the eyes of the UNSC's military arm called the United Nations Space Command Defense Force (UNSCDF). The UNSCDF are commonly seen defending planets. During the events of Halo 2 the UNSCDF fought the Covenant over Earth in a last-ditch attempt to protect the human race.

The UNSC was formed by the United Nations when over-population on Earth started becoming a severe problem in the early 22nd century. Run by HIGHCOM, the UNSC is Earth's premiere defense against the Covenant. The Navy houses the divisions of Marines (including the Orbital Drop Shock Troopers), the Office of Naval Intelligence (ONI), and the fleet. Originally designed to keep the peace between neighboring planets and star systems, when certain rebellious factions began to present a problem in the late 2510s, the UNSC was forced to police its colonies to keep privateers and pirates from raiding them.

There are several breakaway factions opposed to the Colonial Administration Authority and UNSC as well, including the United Rebel Front.

The Covenant


The two original species of the Covenant, the Prophets (San 'Shyuum) and the Elites (Sangheili), spent years locked in a bitter war over the control of the remains of an ancient race, the Forerunners. The Forerunners themselves were long vanished, but still large amounts of their technology existed. The Prophets wished to use the technology to search and explore the galaxy, but the Elites (Sangheili) believed such usage to be a desecration of their holy artifacts. As the devastating war ravaged both species, the Elites saw that the only way for them to win was to do the exact thing they opposed; use their own Forerunner technology to adapt and befit their vessels. The English word "Covenant" means "Religious Alliance" or "Binding Agreement" (between two or more parties), usually used to describe an alliance between a faction of men and a God, or between two factions of men in holy goals. This name is well suited to the Covenant because of the "binding Covenant" formed between the two alien races, the Prophets and the Elites, when the latter promised to defend the Prophets as they searched for the Sacred Rings which are said to start the "Great Journey". The "Great Journey" is the term that the Prophets use to explain the disappearance of their Gods, the Forerunner race. The quest of the entire Covenant, the Great Journey is the basis of all of their worship. As the Covenant Empire grew over a millennium, more species were enslaved to their cause, although, up until the Covenant Civil War, none of them were quite as important to the Prophets as the Elites.

At first, the Covenant were mostly held together by a need to survive, but, as their society advanced, so did their technology, culture and religion. Now the polytheistic Covenant control a large part of the Orion arm of the Milky Way galaxy and their society is a complicated caste system, with the Prophets still on top, governing the Covenant along with the Elites. The Covenant is a theocracy, based on a prophecy about the Sacred Rings and the Great Journey. The actual context of this prophecy is unknown, but the Prophets' faith in it is the reason for their yearning desire to activate the Halos, to "propel all who are worthy along the path to salvation!". A theory is that the promise of the journey goes like this: The Forerunner were so advanced, that they had found a way to propel themselves to God-like status using their technology. To oppose this, a race called the Flood attacked the Forerunner and attempted to stop the activation of this technology, for some unknown motive. Before the Flood could stop them, the Forerunner activated the Halo array, and ascended to Godlike status. The Covenant design is to find the Halo array, and use it to propel themselves to Godliness as well.

The three current leading Prophets, the Hierarchs of the Covenant, want to destroy Humanity due to the threat they pose to their religion: if Humankind really are the Forerunner's heirs, then all that the Covenant believe in is false. Not wanting the truth about humans to get out, the rest of the Covenant have been told that Humanity is a direct affront to the Forerunner, much like the Flood in goal, so must be exterminated if the Great Journey is to be completed.

The Flood


The Flood (called The Parasite by the Covenant) is a species of virulent, parasitic organisms that thrive by consuming other sentient life of sufficient biomass, no matter where in the universe, thus leading Forerunners to the creation of the Halo Array. The Flood appears to be a hive or communal mind, existing in several stages that eventually lead into the creation of a central intelligence known as the Gravemind. Next to nothing is known about their origin, except that they arrived from another galaxy through unknown means, and settled upon a Forerunner world, where they were found and subsequently battled. It has been revealed that the Forerunners discovered and then fought them until they were overwhelmed after centuries of war. Faced with the Flood spreading throughout the galaxy and consuming every sentient being, the Forerunners created seven artificial Rings called the Halos, large Fortress worlds in the shape of rings, to contain and hopefully stop the Flood from ever spreading. The point of the Rings was to wipe out all sentient life, thus starving the Flood of calcium and biomass. Through their own interpretation of Forerunner artifacts, the Covenant believed these rings were actually devices that allowed the Forerunner to transcend this plane of existence into Godlike state, and seek to do the same by activating them once more, though will inadvertently wipe out all sentient life if successful. Although it seemed the plan had been successful at eliminating the Flood threat, samples of the organism kept on the rings for study were released on at least two of the installations through accidental means, putting the Galaxy once again at risk of complete destruction by the scourge. The outbreak on Installation 05, found second, probably occurred first, since a Gravemind had already formed, and the monitor of the Installation captured, though this is merely speculation.

The Flood grow and reproduce via the assimilation of other beings, using corpses and found biomass in order to spread. They are incapable of sexual reproduction, instead they fester inside a host until a certain time period, after which they explode and many new Flood are given off. Once a Gravemind is formed however, the Flood advance to a stage where they no longer require hosts for this, only biomass and calcium, which they require to feed on, and to build bodies with. Once they have advanced, they create hives which can produce thousands of Flood inside large pustules on walls and other surfaces, which act as incubators. During this stage, the Flood are able to build their own life forms using captured biomass and calcium deposits. The Flood continue in this fashion recurrently until either everything is devoured, or until they are stopped, the former usually occurring.

The Forerunners


Once the dominant civilization in the Milky Way, the Forerunners reached the pinnacle of technological advancement approximately 100,300 years before the Human-Covenant War. Apparently charged by the mysterious Precursors with protecting less advanced civilizations in the galaxy, they stumbled upon the Flood and fought a three-hundred-year long war to stop the genocidal parasitic species from overrunning the galaxy. When it looked as if they were going to fail at that task, they built and activated the Halo Array - sterilizing the entire galaxy of sentient life, to starve the Flood into weakness, before repopulating the galaxy again with those few species saved from extinction. This was done post-mortem by their machines - they had all apparently perished in their final action.

All that remains now of the Forerunners are the ruins of their ancient temples and cities, a few scattered pieces of functional technology, and their automated combat and maintenance constructs. Their technological brilliance, combined with a garbled version of the Halo activation, led to the Covenant's religion revering the Forerunners as deities, and that this state could be achieved again by activating the Halo's. In turn, these attempts led to the Human-Covenant War, and the eventual secession of the Sangheili and their alliance with humanity to stop the Covenant.

Superluminal Travel

 * Slipspace, used by both the Covenant and UNSC, it is the primary method of faster than light travel in the Halo universe. A Forerunner crystal captured at Reach allowed for manipulation of space-time and Slipspace, dramatically shortening the length of travel time through Slipspace and allowing exit from the ship whilst in Slipspace.
 * Wheeled contrivances similar in appearance to today's vehicles are used by the UNSC. However, the Covenant prefer to use hovering technology assumed to be based on Forerunner technology.
 * Humans have not exacted the science of Slipspace jumping, and can often end up hundreds of thousands of miles away from where they want to be, and therefore they work to be inexact, so as not to end up somewhere like the middle of a planet. The Covenant had worked a way around this, as they can pinpoint jump anywhere in the galaxy, even maintaining their formation. The UNSC fears this, and that is why they have to keep the location of Earth so secret.

Artificial Intelligence

 * AI's which are modeled after a human brain, work at superior speeds and with greater efficiency; helping with Astronavigation, Maintenance, Managing, and even battle.
 * Standard AI's are incredibly intelligent within their programmed fields whether that be battle strategy, or maintaining plantations on Human colonies.
 * Smart AI's are brilliant and have no limit to their imagination or intelligence other than that of their maximum storage capacity. However, they have a limited lifespan of seven years before they go mad, or "rampant".
 * Little is known of any Covenant AI's, called Associated Intelligence.

Rebellion/SPARTAN-II Project


In the years 2160-2200, various governments and factions fought for control of Earth and its first Colonies. As overpopulation and unrest on Earth mounted, new political movements formed including the Jovian Frieden and Koslovics led by Vladimir Koslov, resurgences of Fascism and Neo-Communism which waged the Interplanetary, Rain Forest Wars Campaign and Mars clashes and were defeated by the victorious United Nations Space Command who emerged as the rulers of most of humanity.

While the UNSC became the governing body for most of Human space they never fully defeated various rebel groups. By 2517, The UNSC was facing extremely low morale due to piracy and the Brushfire Wars. In order to remove the rebellion without a significant sacrifice of Human life a Dr. Catherine Halsey moves forward with the SPARTAN-II project. 75 gifted children were abducted and replaced by flash-clones, and drafted into the UNSC. The children went through rigorous training and physical augmentations. Code-named SPARTANs, these genetically enhanced troopers were trained from the age of six into a life of battle, and would become a great asset against the Covenant.

The Human-Covenant War Begins
On February 3, 2525 the UNSC colony of Harvest detected an unknown object on its long-range radar. The object was constructed with materials unlike anything seen before. All contact with Harvest was lost soon after. Ships sent to the system revealed that it had been totally destroyed by a new alien group called the Covenant. A battle group was sent but was defeated by the military superior Covenant ships. Only one ship made it back, the Heracles returned with a message that was sent to them, pre-translated, saying, "Your destruction is the will of the gods, and we are their instrument". The book Halo: Contact Harvest also takes place here in the view of Avery Johnson. Halo Wars begins at around this time.

In response Vice Admiral Preston Cole mobilized the largest space fleet in Human history to retake Harvest. The fleet defeated the Covenant ships at Harvest in 2531 but at great cost with Cole losing two-thirds of his fleet. The highly advanced Covenant shielding and weapons systems simply outclassed anything they had and so began the slow destruction of the Human race. One by one the UNSC colonies were lost until by 2535, virtually all of the Outer Colony worlds had been destroyed by the Covenant and the Inner Colonies were being invaded. The Cole Protocol was established by military order: all Human vessels must ensure that Covenant forces do not find Earth. To achieve this whenever they must jump out of a battle, they must do so to a randomized vector that points away from any Human worlds. At the same time, Captain Cutter and his ship, the Spirit of Fire, and its crew, go to retake harvest. This took about five years, five long years, as the captain says in his report. As they were there in Harvest, Alpha Base had been attacked.Captain Cutter sent Sargeant Forge to go, find as many suvivors as possible, and retake Alpha Base. After they succeeded, Sargeant Forge goes to scout up north for Covenant activity. So he finds lots of it, and lots of it in an ancient Forerunner Relic. After Sargeant Forge reports this to Captain Cutter, he launches an assault on the Relic, soon to find out that the Covenant are going to blow it to bits. So, they disarm the bombs and go to see whats inside. Profeser Anders soon finds a map of their galaxy. Then they are ambush by the rest of the Covenant forces still inside the Relic. Forge quickly asks for help, and he gets help. Captain Cutter send to Grizzly Tanks to help rescue them. So then, soon enough they get to they LZ. As soon they are back on the Spirirt of Fire, Anders tells Cutter thats it points to another planet. That other planet would be Arcadia, and soon find out that their is a Covenant invasion in Arcadia City. As soon as they gets all of the civilains in the transports, the forces on the ground have to retreat to the outskirts. Then they start building their base in a crater. Then they finish off the rest of the Covenant in the outskirts, including the Covenant Mega Turret. Soon they find a shield dome, like the one on the level, The Covenant in Halo 3. They use the Plasma Rhinos from the Pillar of Autunm invetory. They soon break the shield and go were the Covenant were trying to protect. They soon find a Super Scarab, and they destroy it. Next, Anders and Forge go and look for anything in the area that might help them on why the Covenant are in the area, then a massive elite, or the Arbiter captures Anders and brings her to his ship. Soon the Spirit of Fire finds her signal racing away. Cutter makes the choice to follow that signal and jump into slipspace with the Covenant ship. They soon find themselves in space with another planet, one that is not in any human records. They soon touch down on the planet and fight against a new threat, Brutes. After they finish the Brutes they find something else that is wierd, more and more of their squads keep disappearing. They investagate and they find the answer, The Flood. This is the first human encounter with The Flood. After battling the parasite, they started to build their bases and then destroyed the rest of the Flood Colonies. Then the Spirit of Fire is being sucked in some hole in the sea and the rest of the forces have to get in the ship before they get left behind. They all make it to the Spirit of Fire and then the ship get attacked by the Flood then they destroy the rest of it. Next, the ship gets attackes by a Covenant Cruiser. They fight off they Covenant then rescue Anders, but Anders has learned a horrible truth, the Covenant has just activated a series of Forerunner Dreadknot Keyship to crush the rest of humanity. So then the Spirit of Fire comes up with a plan. They will use a reactor to destroy the ships and make the sun go supernova. They run into trouble as the Arbiter and many Elite forces attack them at the Apex Site. They defeat the Elite forces, but now that the reactor is damaged, on off them has to make they ultimate sacrifice by detonating it manualy, and that person would be Sargeant Forge. So the rest of the Spirit of Fire crew member escapes and Forge detonates the reactor. Then their is no more Covenant, well at least where they are.



The Battle of Reach
By 2552, many of Humanity's Inner Colonies had been destroyed by the Covenant. Halo: Combat Evolved'' takes place at around this time. The UNSC leadership assembled a strike team, including some Spartans, at the Human command base on the planet Reach. In a move of desperation, the UNSC planned to launch a targeted strike against the Covenant leadership. This plan was abandoned when the Covenant launched a surprise attack on the world of Reach.''

During this battle, most of Reach is overrun and glassed, and the Human fleet obliterated. One of the Spartans, John-117, is able to escape on the ship Pillar of Autumn along with her crew. In fleeing the Covenant fleet, the POA onboard AI, Cortana, uses some coordinates from a recently discovered Forerunner artifact that leads them straight to the Forerunner Alpha Halo.

Alpha Halo


The Pillar of Autumn exits Slipspace to find a mysterious ring shaped space station orbiting the gas giant Threshold. The ring, quickly named "Halo," is obviously artificial and teeming with life. A Covenant fleet, however, is also present, and a subsequent battle heavily damages the Pillar of Autumn and the ship crash landed onto Halo. Before the POA went down the ship's AI construct, Cortana, leaves the Autumn with Spartan-117 in a Bumblebee escape pod which also crash lands on Halo. The first Halo game begins in earnest with the Master Chief's escape from the Autumn, and continues upon landing. The first levels of the game deal with an attempt to reach Halo's control center to uncover its purpose. It is soon discovered that the Covenant have accidentally released The Flood, a parasitic alien species. The Flood then sweep across Halo and devastate Human and Covenant forces positioned on it. The release of the Flood prompts 343 Guilty Spark, an eccentric Forerunner A.I., to try to activate Halo's defense system, a pulse weapon that, when fired, would wipe out all sentient life in the galaxy large enough to be hosts for the Flood. Technically, that installation only has a maximum effective radius of 25,000 light years, but the pulse would trigger other installations as well, effectively killing all intelligent life in the galaxy. This system is designed to stop the Flood from spreading through the universe if they escape confinement from Halo by the only way possible: starving the Flood of any life source that can sustain them.

Naturally, this would wipe out Humanity as well, and so the final levels of the game revolve around the Master Chief's attempts to destroy Halo before it fires by self-destructing the POA. Despite the abuse sustained during the space battle and the following crash the Pillar of Autumn remained intact, and was subsequently occupied by investigating Covenant forces and later by Flood.

Having manually triggered a destabilization of the power cores the Master Chief and Cortana commandeered a Longsword from one of the Pillar of Autumn's docking bays and achieved a safe minimum distance before the ship exploded, causing the ring-world to fragment.

Operation: First Strike


Occurs between the first and second Halo video games. The story starts off with Master Chief and a few other survivors in space above the destroyed Halo. They capture a Covenant flagship and make their way back to Reach. When they arrive they find the entire planet ravaged. Yet something is strange. The Covenant usually Glass a world and move on, but there are small patches of the planet left unscathed. In an alternate storyline we find out that other Spartans have found an ancient Forerunner structure under ONI's CASTLE Base. There they find a special artifact that warps space-time.

Cortana, now in control of the Covenant ship, docks with a partially destroyed UNSC ship and combines their power (and also to allow them to return to Earth without violating the Cole Protocol by bringing a potentially "bugged" Covenant ship with them). After toying around with the controls she realizes that the Covenant know virtually nothing about the technology they possess. She redesigns the Plasma cannons to fire more effectively, increasing their destructive power. She also finds out how the Covenant moves so easily through Slipspace. The technology she gathers could effectively turn the tide of the war.

After going through many battles the Master Chief and other Spartans discover a massive plot to attack the Sol system (Earth). They covertly attack and destroy a massive Covenant refit and repair station along with an attack force many times larger than the one that attacked Reach. In doing so they lose the Covenant flagship; however, they save the UNSC ship and escape back to earth with it. Thus begins Halo 2.

Delta Halo


The game starts with a Covenant attack on Earth. Master Chief begins on one of the three hundred space defense platforms that orbit the planet. After repelling the Covenant boarding parties, the battle shifts to Earth's surface. During which a Covenant ship makes a Slipspace jump which destroys the city of New Mombasa, the UNSC ship the In Amber Clad, with the Master Chief aboard gets swept up in the warp field in a desperate effort to follow it.

The player is transported to the vicinity of another Halo ring - the Delta Halo - on which they land. Through an alternating game play story lines a power struggle within the Covenant is revealed, with Brutes usurping the role of the Elites. Furthermore, there is a movement, regarded by the Covenant leadership as heretical, which argues that Covenant teachings aren't true. Lastly, we are introduced to a creature called the Gravemind, which appears to be the controlling mind of the Flood. The creature is obviously highly intelligent and gives the impression of knowing a great deal.

The Halos, we learn from 343 Guilty Spark, were built to prevent the Flood from spreading throughout the Galaxy, and that the Forerunners who built it were wiped out when they fired it as a "weapon of last resort" at some point in the remote past. In spite of this the Covenant activates the ring in preparation to fire, to bring about the Great Journey. Through gameplay the Index is retrieved and the Halo cannot fire. 343 Guilty Spark reveals that although the Index was removed before Delta Halo had time to complete it's firing sequence, it sent signals to other Halos in the Galaxy, putting them on standby mode. Now, they can be activated remotely from the Ark (assumed to be either on Earth or the Forerunner Ship itself). The game ends here and the credits roll.

After the credits end, one final cut scene plays. The Gravemind has taken control of High Charity and with it, Cortana.

Battle of Onyx


The novel, which tells the story of the battle, begins with a group of SPARTAN-IIIs deploying to a Covenant fleet refueling depot on Pegasi Delta. They proceed to destroy the facility, but due to unexpectedly heavy Covenant resistance, all but two of the three hundred Spartan team is wiped out. The only survivors, Tom-B292 and Lucy-B091, are revealed to be only twelve years old, and Lucy is traumatized and rendered mute.

The novel then cuts to a raid by the SPARTAN-II Blue Team on a rebel base at planet Victoria to recover stolen nuclear warheads. The team is nearly captured by a rebel ambush, but is saved by the timely, intuitive intervention of Kurt-051. Shortly afterward, the novel cuts to a meeting between the top leadership of ONI. In this meeting, they agree that the SPARTAN-II program is prohibitively expensive and that a more streamlined, "disposable" breed of Spartans must be trained for high-risk operations.

Trained on the restricted planet of Onyx the top three teams of the S-III Gamma Company, Teams Saber, Katana, and Gladius, conduct a training exercise run into some previously undiscovered Forerunner Sentinels. Through a series of events the Covenant are herd to the existence of Onyx and the human force discover an ancient Forerunner city, and are guided into a massive dome by Halsey, who determines that the entire planet is a shield world referred to by the Forerunners as The Sharpened Shield. Fighting off determined Covenant pursuers, they press on into the heart of the planet to discover that the planet is literally a massive bomb shelter for the Forerunner to survive the activation of the Halos. However they find themselves alone in the vast habitat; for some reason, the Forerunner never entered this structure when the Halos were first activated. Kurt-051 stays behind to activate a pack of FENRIS warheads, thus killing himself, the Covenant pursuers, and obliterating Onyx.

Halo 3: ODST
Halo 3: ODST is a campaign expansion pack of Halo 3, set to be released in Fall 2009. It tells the story of what happened after the Covenant slipspace jump that destroyed the port city of New Mombasa in Halo 2, as seen from the eyes of The Rookie, an ODST, and his squadmates. Spartan-117 does not appear in this game, since he is on Delta Halo at the time.

Second Battle of Earth and Installation 00


Halo 3 takes place some time after the end of Halo 2, presumably a number of weeks or even months. The Covenant have presumably taken control of most of Earth, but are particularly interested in East Africa, near the ruins of Mombasa. Marines and the Arbiter recover the Master Chief after jumping from a Forerunner Ship, and they all make their way back to the local UNSC base. The Master Chief defends the base, and is cut off, along with a small group of Marines. They make their way to the town of Voi through numerous Covenant outposts.

It is revealed that a large Forerunner artifact has been dug up under the African desert by the Covenant, and the Prophet of Truth is going to activate it. Presumably this is the Ark, so therefore this would activate the Halos, and so a hasty attack is set in motion by Lord Hood to destroy the Forerunner Dreadnought with a surprise aerial assault. Master Chief clears Voi of all Covenant anti-air units to clear the path for Lord Hood's frigates for an assault on the dreadnought. However, the assault on the dreadnought has absolutely no effect, and Truth activates the artifact all the same. A large portal is created above the artifact, into which the Covenant forces disappear. Soon after, a derelict Covenant cruiser appears out of slipspace, and crashes nearby, infested with Flood.

The Master Chief and the Arbiter make their way toward the ship, and as they near its location, a group of Elite-controlled cruisers appear, striking up an alliance with the Humans and helping rid the city of Flood. Master Chief enters the ship and retrieves a message from Cortana, warning that High Charity is heading to Earth, full of Flood. It is decided that only the frigate Forward unto Dawn, the ship of Miranda Keyes, along with the Elites, will go through the portal after Truth, and stop him from activating the rings, as well as finding the 'solution' to the Flood that Cortana's message spoke of.

The Human/Elite force arrives at the Galactic Halo, or The Ark, and engage the Brute fleet. Master Chief makes landfall and finds the Cartographer of the Ark, which leads him to the location of the remaining Covenant Loyalist forces, at the Citadel. This leads to a trident strike at three shield generators guarding the Citadel at the heart of the Ark. Once all three generators have been deactivated, The Master Chief and the Arbiter breach the Citadel after Truth kills Miranda Keyes and forces Sergeant Major Avery Johnson to activate the rings. Upon executing the Prophet of Truth, the forged alliance between the UNSC-Separatist Forces is broken, as their cause to eliminate The Covenant is complete. After the Master Chief and the Arbiter escape the Flood, they discover that a new Halo is being built to replace Installation 04 which is nearly complete. The Master Chief decides that the only way to destroy the Flood was to activate the newly built Halo, which was out of range of the other installations, with Cortana. The Arbiter leaves to gather the surviving forces and get them ready to leave, and the Master Chief heads to the crashed High Charity to recover Cortana. After wading through tantamount to infinity of Flood, he recovers her and escapes to the new Halo with the Arbiter.

After fighting their way up to the top of the Control Room, the Master Chief and the Arbiter enter the Control Room, and attempt to activate the ring. However, 343 Guilty Spark attempts to stop The Chief and Johnson from activating the ring, saying that the charging sequence of the incomplete Halo will prove too much for the structure, and cause it to tear itself apart. In the fight, 343 Guilty Spark mortally injures Johnson, but fails at killing Master Chief, whom destroys him with four shots from a Spartan Laser. They succeed in activating the ring, however as expected, the installation begins to fall apart, and once more does Master Chief makes an attempt to escape Installation 04 in a Warthog. The two board the Dawn, which then proceeds toward the portal. The Dawn heads into the portal just as Halo fires, which closes as it gets halfway through shearing the Dawn in half.

Half of the Dawn, as well as the Arbiter, crashes back on Earth, and a memorial service is held for those who perished in the Covenant/Human war, ending on the note of the Master Chief's death.

At the end of the credits, a last cut scene shows that the Master Chief survived, and put himself into cryosleep, as Cortana activates a distress beacon. The rear half of the Forward Unto Dawn is seen hurtling through space toward what most fans believe to be a Forerunner planet.

In Our Universe
The first Halo title Halo: Combat Evolved quickly became known as the first "Killer App" for Microsoft's popular Xbox video game console when it was released in 2001, achieving both critical acclaim and financial success. Halo was later published on the PC and finally released for the Mac (for which it was originally developed prior to Microsoft's acquisition of developer Bungie). Shortly after that, the company (Gearbox Software) that ported Halo to PC released Halo: Custom Edition as a free, downloadable and achievable extension to the Windows port of Halo.

The second game, Halo 2 was released in 2004, breaking sales records and becoming the fastest selling United States media product in history. Halo 2 US sales top 125 million dollars; UK retail celebrates successful launch September 7, a possible 7 reference.

A third game, Halo 3, is now released for the Xbox 360 and closes this chapter in the Halo series. The Halo games have become well known for the high quality of their graphics, gameplay, physics, and storyline. Further expanding the Halo universe are several novels, which provide insight into the background story, and three upcoming Xbox 360 projects: a Halo RTS (Real Time Strategy) named Halo Wars, Halo 3: ODST and Halo: Reach.

Rival Game Series
Like many great games, Halo is not uncontested for the title of "Greatest First Person Shooter." One of the Halo series's biggest rivals is the Call of Duty series. Some others are the Medal of Honor series, the Battlefield series, and the Brothers in Arms series. Aside from the Call of Duty series, the game Gears of War has rivaled the Halo series since its post-Xbox 360 release.
