Halo 3

Halo 3 is a First Person Shooter video game, based on the science fiction events and settings in the Halo Universe. It was developed by Bungie Studios and has been published by Microsoft. It has been released as an exclusive game for the Xbox 360.

Halo 3, is the sequel and concluding part to Halo 2 which fully wraps up the current story arc that the previous two games told. It involves SPARTAN John-117 returning to Earth in order to stop the Prophet of Truth from activating The Ark which would result in the extermination of all sentient life in the galaxy. Shortly into the game he also has to contend with the arrival of the Flood on Earth, as well as retrieve Cortana from the clutches of the dreaded Gravemind.

Even though the game does not progress directly on from the end of Halo 2's cliff hanger, Halo: Uprising a mini comic book series released by Marvel will fill in the missing segments between Halo 2 and Halo 3.

Halo 3 was released on the long awaited September 25 in North America and Australia, the 26th in Europe, and the 27th in Japan. It has been rated M for Mature (blood, gore, violence, and language) by the ESRB, but only M 17+ Recommended for 17 years or older, not restricted-(this is only a rating for parental guidance) by the OFLC, but in many stores, like GameStop, ID was required because anyone under the age of seventeen is unable to buy a copy of Halo 3. Europe's PEGI rating system gave the game a '16+' rating, which serves as a guideline rather than as a rule.

Plot
The storyline begins several weeks after the events of the Halo 2 era. John-117 - the Master Chief, enters Earth's atmosphere and crash lands in an east African jungle. Sergeant Major Avery Johnson, the Arbiter, and a handful of Marines retrieve him, and the group makes their way through the jungle toward a designated extraction point. Covenant forces are sighted in the area and Johnson makes a strategical decision to split the group up to reduce their chances of getting spotted. Master Chief and the Arbiter continue on their way to the extraction zone with second squad, fighting off numerous Covenant troops in the process, but upon reaching the extraction zone, Johnson's Pelican group consisting of two Pelicans, are ambushed and shot down by two Banshees. Johnson and his men are then captured and taken prisoner by a number of Brutes. The Master Chief, Arbiter, and company fight their way through hordes of enemies and eventually rescue them, after which a Pelican arrives and picks them up.

The Pelican brings them to Crow's Nest, an underground 21st century facility used as a local base of operations by the UNSC. Here, Commander Miranda Keyes and Lord Hood plan a last-ditch effort to stop the Covenant from activating a Forerunner artifact uncovered outside the ruins of the city of New Mombasa, which is assumed to be The Ark - from where Truth is able to activate all the Halo rings in the galaxy. Their planning is quickly interrupted when the Prophet of Truth broadcasts an announcement to all surviving human forces that their doom is inevitable. Soon after that, the Covenant discover the facility and mount an heavy assault. After a brief struggle, the outpost is lost, due to an explosion of a bomb the Chief activated to clear all remaining Covenant forces still inside the base. Master Chief soon receives orders from Commander Keyes to clear a way into the African City of Voi, Kenya via Tsavo Highway, and destroy all Covenant anti-air defenses so that Lord Hood can lead the last of Earth's frigates against Truth and the artifact. Using the opening caused by the ground attack, Hood mounts an all out attack on Truth, but the Prophet activates the artifact and creates an enormous slipspace portal, into which all the Covenant ships retreat. At the same time, a Covenant cruiser controlled by the Flood, a parasite species, suddenly arrives via slipspace and crashes into the nearby Voi, and the parasite quickly spreads throughout the entire city.

As the Human forces attempt to fight the infestation, many are infected by the Flood. Soon after the struggle begins, Covenant Separatists, a legion which broke off from the entire Covenant during the Halo 2 era, arrives at Earth and assists the struggle against infestation, dropping off Orbital Insertion Pods containing allied Elite warriors via the Carrier Shadow of Intent and a few other Separatist cruisers. The Elites inform Commander Keyes that an UNSC construct is aboard the crashed Flood ship, and identify it as Cortana. The Master Chief, Arbiter and the Elites fight off many Flood forms and retrieve Cortana from the Flood ship. 343 Guilty Spark (the Elites refer to him as the Oracle) arrives by an Elite dropship, a Separatist Phantom, and insists that he take Cortana somewhere where he can make repairs, claiming that now his Installation has been destroyed he has no more present functions, and wants to help the Master Chief destroy the Flood. Once the Arbiter and the Chief are evacuated, the Elites glass the entire infected half of Africa to prevent the Flood from spreading, which amplifies the hard feelings between Lord Hood and Rtas 'Vadum, Shipmaster of the Shadow of Intent and Fleet Master of the current Covenant Separatist force.

343 Guilty Spark manages to make efficient repairs to Cortana, but the Master Chief realizes it isn't her, but only a recorded message from her. The message states that the portal that Truth retreated into is unknown to the Gravemind, and on the other side is a solution to the Flood infestation, without having to fire the rings. Lord Hood questions Cortana's plan, saying it could be a Flood trap, but the Master Chief firmly tells Hood that he completely trusts her.

Once the Elites and Commander Keyes decide to follow Truth, the remaining Elite and UNSC ships leave Earth via the activated slipspace portal. On the other side, they find themselves near an immense artificial structure, which is soon revealed to be the real Ark. Arriving at the Ark, they engage a Covenant fleet three times their size. After landing on the structure, Guilty Spark helps lead Master Chief and the UNSC armor force to the Cartographer, or map room of the Ark. After fighting their way in, Chief and the Arbiter find out that the Ark is in fact positioned at the edge of the Milky Way, just beyond the Halo rings' effective firing range. Soon Spark, understanding a Cartographer, explains that the UNSC and the Separatists must deactivate three shield generators, which are inside three separate towers, to access the Control Room of the Ark, where Truth is currently located and plans to activate the rings from.

Upon arrival at the three generators, the Master Chief takes an ODST squad to the first tower, while the Arbiter takes his Elites to the second, and Sergeant Johnson takes another squad to the third. While Master Chief and the Arbiter succeed in deactivating the first and second towers, Johnson radios Keyes, telling her that the enemy forces are too heavy and he must retreat. Keyes orders the Arbiter and Master Chief to go and assist him. On arrival to the third tower, Johnson and his men are nowhere to be seen. Master Chief, Arbiter, and the Elites kill the Loyalist force defending the tower and deactivate it. However, just after the final shield barrier protecting the Control Room deactivates, the Flood-infested High Charity arrives by slip-space and crashes onto the Ark, releasing Flood Dispersal Pods as it falls. Guilty Spark insists that he assesses the damage that High Charity did to the Ark, so the Arbiter and Elites leave the UNSC to protect Spark being captured by the Flood. The Chief leads the remaining UNSC and surviving Elite force via vehicles in an attack on the Citadel containing the Control Room, which is defended by numerous Covenant armor forces. After all the forces are defeated, Guilty Spark and the Arbiter return, which the Arbiter and the Master Chief enter the citadel alone to avoid more casualties. Once inside, they see that Truth has captured Johnson, knowing that only humans can activate Forerunner Installations, but are too far away to save him. Just as Truth is about to force Johnson to activate the rings, Keyes commandeers a Pelican and crashes it in the Control Room, keeping the Brutes at bay with a Shotgun while tending to Johnson. Knowing she can't kill all of the Brutes, she realizes she must kill Johnson and herself to stop the rings from being activated. She is about to shoot Johnson before Truth grabs a Spiker and shoots her with several shots in the back with it, killing her. Truth then pushes Johnson's hand down on the Ark's terminal, activating all of the Halos in the galaxy.

Then Master Chief and Arbiter take an elevator up to the Control Room, despite knowing it is too late. As they reach the top, two Flood Tank Forms confront them, but say that the only way to stop the Halos is by joining forces. With the Flood's help, the Master Chief and Arbiter kill all the Covenant forces defending Truth. Upon arrival to the Ark's terminal, they find Johnson mourning over Keyes' dead body, and Truth partially infected. The Arbiter executes Truth with his Energy Sword, and the Master Chief deactivates all the Halos, and Johnson is seen walking away with the body of Keyes. After the rings are stopped, however, the Gravemind betrays them. Johnson attempts to escape with Keyes' Pelican, but the Gravemind prevents the Arbiter and Chief from escaping with him.

Johnson radios Chief, telling him to find another way out, so he and the Arbiter shoot their way back to the entrance elevator, but it is deactivated. Behind the elevator is a hole, leading to a lower level of the citadel. Cortana briefly shows herself to the Chief, and leads him to a control panel which reveals her plan - The Ark releases a 'replacement' Halo in the event of one being destroyed. The Chief decides he's going to light the single ring in order to destroy the Flood for good. However, Guilty Spark tells them it will take quite some time to fabricate an Index needed to fire the Halo, but Master Chief remembers that Cortana still has the Index that she acquired on Installation 04. He infiltrates the crashed High Charity, which is completely overrun by Flood. Cortana becomes rampant before the Chief can reach her, but she is able to contain the functional part of herself in a stasis-field, where she waits. Master Chief breaks the stasis-field and retrieves a perfectly functioning Cortana. She tells him to overload High Charity's engines in order to destroy the Gravemind. The Arbiter arrives via Banshee and helps the Chief fight the Flood. They find a Pelican, which had presumably crashed while the Flood used In Amber Clad to infect High Charity during the Halo 2 era. Damaged but still flyable, the Master Chief uploads Cortana into the Pelican and both him and the Arbiter flees High Charity before it explodes.

Cortana makes contact with Johnson, who safely made it back the Shadow of Intent along with the other human and Elite survivors. He tells her that he will land the frigate Forward Unto Dawn near Halo's Control Room, and will be ready to pick them up and head back to Earth after they activate the Installation. When they arrive on the newly built Halo, they quickly discover that Gravemind is attempting to reconstruct itself on the new ring. The Chief, Arbiter, and Johnson quickly make their way to the Control Room, where they attempt to fire Halo. However, Guilty Spark realizes that this will destroy his new ring because it is not fully ready yet, as well as the Ark, and shoots his defensive laser at Johnson as he tries to activate the ring. The Forerunner construct soon turns on the Master Chief and the Arbiter, which locks him out of the room, leaving the Spartan to destroy Spark himself, but Johnson is critically wounded. He tells the Chief to send him out "with a bang" and dies. Cortana activates Halo, and Chief takes Johnson's Warthog with the Arbiter and race towards the Frigate. With no time to reach the cockpit, the Master Chief uploads Cortana into the frigate to start taking off before the Arbiter is able to take the controls. The front half of the Dawn, containing the Arbiter, makes it through the portal. However, as Halo shakes itself to pieces during it's firing sequence and damages the Ark, the portal deactivates before the other half of the Dawn containing Chief and Cortana make it through.

Back on Earth, Lord Hood holds a memorial service in respect for those who died in the Human-Covenant War, with the Arbiter and many Marines in attendance. With Truth dead, the Covenant destroyed, and the Flood wiped out, the long and devastating war is over. Lord Hood thanks the Arbiter for standing by the Master Chief until the end. Everyone thinks the Chief is dead. After the service, Shipmaster tells the Arbiter that he wants to make sure the Elite homeworld is safe. The Arbiter tells him that with the eradication of the Covenant, they have made it so. He tells the piloting Elites to take them home, and the credits roll.

After the credits, it is revealed that the Master Chief and Cortana are still alive on-board the rear section of Forward Unto Dawn, which had apparently torn off during the slipspace jump; the pair are drifting through space. Cortana tells the Chief she will drop a distress beacon, but that it could be years before they are found. The Chief floats to a cryotube, and as he is climbing in Cortana comments "I'll miss you." He replies "Wake me, when you need me."

If the game is completed on Legendary difficulty, the section of Forward Unto Dawn that Cortana and the Chief are aboard is seen drifting towards an unknown planet.

Service Tags
The Service Tag is how you and your teammates can be identified quickly on the battlefield, instead of the long names and complex number combinations. The service Tag is comprised of a letter followed by two numbers. A few examples of Service Tags are K90, C27 and A12. When certain specific Service Tag coding is entered for example I17 (117) a message will appear stating "This Service Tag is currently in use by the UNSC". Another error will happen when "N64" and "P52" (Nintendo 64 and Playstation 2) are entered but this is due to trademark infringement of the companies, and as a result the service tag will not be allowed. If you put in "A55" it will also state that you can't use the tag. There are also bans on the tags, "N00", "P00", "FOO" and "J00". T17 is also banned for reference to breasts.

According to Bungie, as of March 14th the most used Service Tags by players of Halo 3 are, in descending order, O07, M16, I69, P26, S80, H20, I87, and finally D13.

Service tags are designed to help you locate your co-op partner easier and faster. It is useful for levels that are difficult and are at a higher difficulty.

Armor Permutations
There are two player models which you can choose from, the standard Spartan model or the Elite model. Each model has several armor permutations which can be combined. All Armor permutations do not have any special effects during gameplay.

Spartan

 * MJOLNIR Mark VI armor - The standard Spartan armor.
 * MJOLNIR Mark VI [C] variant - The Close Quarters Battle (CQB) armor.

Currently the Recon Armor Permutation is only allowed to certain people who perform special and unique things in Halo 3 and bungie employees. Another special variation is a Flaming helmet that only Bungie Employees are allowed to use. It is normally so that in the mass of matches online, you as the player know that you are playing against a Bungie Employee. According to Bungie on March 14th 2008, Weekly Update;

An Emblem is a highly customizable image that appears on the right arm and the back of the player's avatar.

Emblems also show your teammates what Spartan you are. This was made by the ONI Research Center of the Spartan Program and has no use at all since the Spartans can check each other through Service Tags, so Emblems are just an addition.

According to Bungie on March 14th 2008, Weekly Update;


 * Most Popular Emblems: Phoenix, Jolly Roger, Valkyrie, Crossed Sword and Champion

Colors
There are 10 base and primary colors, each with three shades of one another that are used to customize your multi player color and emblem. On the armor detail color, there is a small painted VI (most noticeable on Mark VI shoulder), and there is a stripe on the Spartans' leg.
 * Steel, Silver, and White
 * Red, Mauve, and Salmon
 * Orange, Coral, and Peach

 * Black can still be used but, only in Forge or Custom games types, as a forced player color under general settings.

According to Bungie on the March 14th 2008, Weekly Update;

Veto
The Veto system is new for the Halo franchise. Vetoing a map and game type is a very useful thing these days. It's also easy. In a game, after the map and game type loads for each player, a 10 second countdown starts. If the majority of players (more than half the players) in the match decide to veto, by pressing (X), before the countdown ends, a different map and game type from the playlist will be selected to be played on.

For Example: If there are a total of eight people in the game (a classic four versus four), and five or more people veto, the map and game type will change. If only four veto however the map and game type will remain and be played on.

If a map is vetoed, the option to veto will be lost during the next countdown. Sometimes you will see the map and game type change, but you still get the veto option, this is just because the host's connection cannot support the map, or if anyone in the party cannot play the map. When this happens, you still have the right to veto the next map and game type. However, you cannot veto on certain game types such as Grifball.

NOTE: On certain gametypes, like Team SWAT, the gametype will be rarely change from only three types, but from no lack of maps, the map will certainly change.

Ranks
The ranking system is based on real military ranks. To progess in Rank, players must earn the required amount of EXP. For Officer ranks, players must also reach a certain skill level in a ranked playlist. If a player earns a certain amount of experience, but does not reach the required skill level to reach the next officer rank, they will instead be promoted to a higher grade of their current rank (For example, A Major who earns 300 EXP but does not have a skill level of 35 will be promoted to Major, Grade 2).

Each Officer rank has a "final" grade which is represented by a unique name instead of a number.

Halo 3 uses the Trueskill system created by Microsoft to determine skill level in ranked playlists.

Forge
Forge is an "object editor" that can be used to edit multiplayer maps. It does not allow as much freedom to edit/make maps as a pc map editor, such as the Halo: Custom Edition and Halo 2 Vista editing kits. You can, however, edit objects, spawn points, weapons, and properties of objects on the map, etc. And, when playing a map on forge, players may take control as a monitor (very similar to 343 Guilty Spark) and will obtain the ability to spawn weapons, vehicles and objects in-game, as well as move/adjust them too.

Map Variants
To save a Map Variant while playing forge, press Start and select save changes to overwrite the previous Map Variant or select Save As and give it a name. But if it doesn't say save changes just save it as a new one and just call it a different name and delete the other one you made.If you are interested in forging maps there is a website for it called Forge Hub.

Theater
The Theater mode allows players to save films from the Campaign, Multiplayer, and Forge, and also get film clips and screen shots. This feature of Halo 3 has been exploited for making Machinima videos and Montages.

Films
Saved Films allow a player to view any game, campaign or multiplayer, from any angle. It uses game data to re-create the games, which makes file sizes very small (5 MB for a 15 minute multiplayer match). In the film, you can either watch your own player play through the entire mission or you can go a different way: bird's eye view. You can go anywhere you want, but they will limit your movement so that you cannot fly as high as possible or go very far from your character. You can also fast forward or rewind the film so that you can relive the parts you missed. On Campaign you can't rewind the film. Only your previous 25 games will be saved under the recent films category on your console. Older films will be deleted.

Clips
When playing a film you record a particular part of the film from any angle you want. Doing this allows you to look back at your greatest moments without having to watch the entire film, however, sometimes the HUD will not show up in a first person view, or the time bar showing the elapsed time appears, which is normally a problem because it normally can't be removed or the HUD can't be brought up for the start of the clip. If you would like to make a clip in FPS mode, but you accidentally get out of it, or switch to another player, you can just click on the right thumbstick to return to FPS mode. You cannot record clips of campaign films, but you can take screenshots. If you are in a party viewing a film, you will not be able to record clips, nor take screenshots.

Screenshots
Screenshots can be taken in any kind of film; all screenshots taken by Xbox Live players are sent to Bungie.net via the Internet. You must be in single-player theater or film to take a screenshot.

Soundtrack
The Halo 3: Original Soundtrack was composed by Martin O'Donnell with the help of Michael Salvatori and was released on November 20, 2007. It is a two-disc set featuring all the music heard in-game, in order of appearance.

As the Halo: Original Soundtrack, the music is in more of a medley format. However, similar to the Halo 2: Original Soundtrack Volume 2, tracks are divided into 'suites' corresponding to each level in the game.

A number of bonus tracks and a third-party song will be contained on the second disc of the album: 'LvUrFR3NZ' by Princeton.

Previews of the Halo 3: Original Soundtrack can be heard on the official site.

Viral Marketing
On June 11th, 2007, at 10:26AM PDT, a viral marketing campaign for Halo 3 started, called "Iris".

Announcement Trailer
At E3 2006, Bungie released their announcement trailer. It required long hours and hard work from many, many Bungie staffers, and utilizes real-game assets, fiction and locations from parts of the "real" game. It shows John-117 walking through some wreckage of the New Mombasa space elevator with Cortana appearing at several intervals to give her lines. He then stops at the edge of a cliff where the Covenant forces are hovering over a Forerunner structure (believed to be the Ark). The trailer ends with the Forerunner structure opening and firing a beam of light.

The Trailer fueled speculation about what was going to happen in the game, particularly Cortana's last line in the trailer: "This is the way the world ends," which references the first of the Cortana Letters. The line itself refers to T. S. Eliot's The Hollow Men, which ends:


 * This is the way the world ends
 * Not with a bang but a whimper.

Cortana's emphasis on "this" implies she is rejecting the poem, and that the world will end with a bang - likely referring to the Halo installations being activated.

Starry Night Trailer
Starry Night Trailer was released on December 4, 2006 with its format designed for TV Ads. It shows two children staring at the stars talking about whether there are aliens before switching to a dazed Master Chief recovering from some form of blast. Once he gets back on his feet, he uses a Bubble Shield to defend himself from an incoming Wraith plasma mortar and then charges forward, eventually jumping over a cliff into a swarm of Covenant Loyalists. It has been rumored that the two kids are John and Kelly when they where young.

E3 2007 Trailer
The final trailer for Halo 3 was released during E3 2007. Unlike the others, this trailer focused on showing various gameplay and movie clips. While the trailer did little to further knowledge about the Halo 3, it confirmed many speculations about the game, the least of which was that the Arbiter and the Master Chief will fight alongside one another in the game at some point.

Believe
Believe is a Microsoft marketing campaign for Halo 3.

It features the word "Believe" as a tag line, and appears to be honoring the legacy of SPARTAN-117, citing him as a hero of the United Nations Space Command Defense Force whose brave actions inspired other servicemen during the Human-Covenant War. It has also been cited that it has been linked to the popular message board Neogaf.

Landfall
Halo: Landfall is a trilogy of short films designed to promote Halo 3 as well as test the potential for a live-action Halo Movie.

Reviews and Reaction
Halo 3 has received mainly positive reviews from both the online gaming sites and country specific magazines. Each review has praised it, stating "the winning formula is still apparent" with "multiplayer constantly surprising and engaging", while new features of Forge and Saved Films were singled out as particularly interesting new features.

The Campaign was considered by many to be a negative, with many pointing out it is "too short", the artificial intelligence of the player's allies were referred to as "Cannon Fodder" with most of the time no reason to have them on your team, and the graphics was highlighted saying some Human characters and textures were "embarrassing" to look at not to mention a little over done.

Halo 3 has won a number of awards from its first release date:


 * Spike TV Awards: Best Multiplayer Game, Most Addictive Video Game Fueled by Dew.
 * TIME: Game of the Year.
 * Geezer Gamers: Geezer Game of the Year, Multiplayer Game of the Year.
 * Gametrailers: 2007's Best Xbox 360 Game of the Year.

Trivia

 * I17 is not allowed as your service tag in multiplayer, it says it is already reserved by UNSC, in use by Master Chief Petty Officer John-117.
 * On the legendary ending after the credits, the lights on the planet form the Marathon symbol, a Bungie trademark.
 * For Christmas 2006, Microsoft and Bungie gave the U.S. soldiers in Iraq a chance to play the Halo 3 multiplayer public pre-alpha.
 * On the Cops & Robbers commercial for the 360 at the Xbox Live Marketplace, one of the license plates says HA LO307, a.k.a Halo 3 07.
 * The game has 39,377 lines of dialogue, most of them randomly triggered during gameplay.
 * In several of Cortana's messages to the Chief, she quotes Dr. Halsey's lines from the book, Halo: The Fall of Reach. This is logical considering Cortana was created with a flash clone of Dr. Halsey's brain.
 * Halo 3 is the only Halo game to feature Forge.
 * The chances of two people having the same service tag on Xbox Live is 2574 to 1.
 * Throughout all of Halo 3's storyline, the Master Chief's codename is Sierra 117, which the first level is named after.
 * We hear the Master Chief's real name "John" for the first and only time in the playable side of the Halo series on the Halo 3 level 'Halo' (i.e., Halo: Combat Evolved and Halo 2).
 * On the level The Covenant, a secret piece of music is played, it is called Siege of Madrigal,this is a nod to Myth, an older Bungie game. The music has appeared in the previous games, Halo: Combat Evolved and Halo 2, and require almost similar conditions of going to obscure areas to hear. How to reach the area on Halo 3 is shown here.
 * Halo 3 contains 49 achievements, which is a seven reference 7x7=49
 * In Halo 3's legendary ending you can see a red galaxy off to the side of our galaxy. Also there is a large planet at the very end. It is rumored to either be a Flood or Forerunner planet.
 * Just as the Chief and the Arbiter enter the Citadel after the level The Covenant, Cortana will give another message, actually Gravemind, but the message will also be displayed upon the screens either side of the room where in the next cut scene, the Prophet of Truth is giving his speech.
 * Halo 3 is the only Halo game that allows you to start from specific parts in the level.
 * Halo 3 is the only game in the Halo trilogy that allows you to watch the exact same level that was previously played. (Hard Drive needed).
 * The kill count in Halo 3 has surpassed the population of Earth, and on Bungie.net, people are wondering if the it will go as high as 7 billion before Bungie day. (7/7).
