Plot synopsis
The storyline begins approximately two weeks after the events of Halo 2, on November 17th, 2552. John-117 enters Earth's atmosphere and crash-lands in an east African jungle. After being retrieved by Sergeant Major Avery Johnson, Arbiter Thel 'Vadam, and a handful of Marines, the group makes their way through the jungle toward a designated extraction point. Covenant forces are sighted in the area and Johnson makes a strategic decision to split the group up to reduce their chances of getting spotted. John-117 and Thel 'Vadam continue on their way to the extraction zone with the second squad, fighting off numerous Brute-led Covenant troops in the process, but upon reaching the extraction zone, Avery Johnson's Pelican group consisting of two Pelicans, are ambushed and shot down by Banshees. Johnson and his men are then captured and taken prisoner by a number of Brutes led by a Brute Chieftain. John-117, Thel 'Vadam, 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 which is used as a local base of operations by the UNSC. Here, Commander Miranda Keyes and Fleet Admiral Terrence Hood plan a last-ditch effort to stop the Covenant from activating an artifact built by the long-vanished Forerunners who the Covenant worship as gods, uncovered outside the ruins of the city of New Mombasa. This artifact is believed to be the Ark, which, if activated, will fire the Halo Array, which the Covenant believe will herald a sublimation event called the Great Journey and propel the faithful to godhood, but will in fact wipe out all sentient life in the galaxy. Their plan is to have John-117 and a small group of marines punch a hole in the Covenant's anti-air defenses, so that Lord Hood can initiate a low level air-strike on the artifact. Their planning is quickly interrupted when power is cut and the High 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 a heavy assault. After a brief struggle, the outpost is lost and is destroyed by a bomb activated by John-117. Deep underground, the Master Chief regroups with the surviving Marines and makes his way into the African city of Voi, Kenya via the Tsavo Highway. In Voi, John-117 along with a handful of Marines destroy the Covenant anti-air defenses. Lord Hood leads the last of Earth's military ships against Truth and the artifact. As Hood mounts his attack on the Prophet, Truth activates the artifact and creates an enormous slipspace portal, into which all the Covenant ships retreat.

At the same time, the Indulgence of Conviction, a CCS-class battlecruiser controlled by the Flood, a parasitic species which nearly wiped out the Forerunners, arrives suddenly via slipspace and crashes in Voi. The parasite quickly spreads throughout the entire city and infects many, minutes after they arrive. As the Human forces attempt to fight the infestation, many become infected by the Flood. The Sangheili, led by Shipmaster Rtas 'Vadum, arrive at Earth and assist the struggle against the infestation. The Elites inform Commander Keyes that a UNSC construct is aboard the crashed Flood ship, and identify it as Cortana. After retrieving Cortana, John-117 returned to the Elites' flagship, Shadow of Intent, to oversee the repairs made by 343 Guilty Spark. However, it is only a recorded message from her. Cortana's message says that the Gravemind is bringing the infested High Charity to Earth with an army of Flood, and that on the other side of the portal is a solution to the Flood infestation, without having to fire the rings. Lord Hood questions Cortana's plan, assuming that it could be a Flood trap, but John-117 firmly tells Hood that he trusts her.

Lord Hood and the rest of the UNSC remain on Earth to defend it against the incoming Flood invasion while Commander Keyes and the Elites journeys through the Portal. Arriving at the true Ark, which is several thousand light years beyond the rim of the Milky Way, the Sangheili engage Truth's fleet while the UNSC launches a ground campaign. After landing on the Ark, 343 Guilty Spark helps lead the Master Chief and UNSC forces to the Ark's Cartographer, the map room of the Ark, to locate the Control Room of the Ark. In order to access the Control Room, the UNSC and the Sangheili must deactivate three shield generators which are inside three separate towers. While SPARTAN-117 and the Arbiter succeed in deactivating the first and second towers, Johnson radios Keyes, telling her that he must retreat due to the heavy enemy assault. When John-117 and the Elites arrived to the third tower, Johnson and his men are nowhere to be seen. After the final shield barrier protecting the Control Room deactivates, the Flood-infested High Charity arrives via slipspace and crashes onto the Ark, releasing Flood dispersal pods as it falls.

After handling the nearby infestation, John-117 leads the remaining UNSC and surviving Sangheili forces via armored vehicles in an assault on the Citadel containing the Control Room, which is heavily defended by Covenant forces. Once inside the Citadel, Truth broadcasts his sermon and reveals the captured Johnson to his followers. Just as Truth is about to force Johnson to activate the rings, Keyes crashes into the Control Room using a Pelican. Knowing she cannot kill all of the Brutes, Keyes realizes that she must kill Johnson and herself to stop the rings from being activated. From behind, Truth kills Keyes, and then using Johnson's hand on the nearby terminal, activates all of the remaining Halos in the galaxy.

Just as John-117 and Thel 'Vadam reach the top, two Flood tank forms confront them. The Gravemind, communicating through the two Flood forms, urges the two to join forces in stopping the initiation of the Halos and Truth. With the Flood's help, John-117 and Thel 'Vadam slaughtered all the Covenant forces defending Truth. Upon arrival to the Ark's Control Terminal, they find Johnson mourning over the loss of Keyes, and Truth partially infected. Thel 'Vadam, after a short confrontation with Truth over the true purpose of the Halos, executes Truth with his energy sword, just as John-117 deactivates all the Halos. Shortly after the deactivation of the Halos, the Gravemind betrays them and prevents the duo from escaping, although Johnson manages to using Keyes' crashed Pelican.

The duo manages to escape from the Citadel via an access tunnel near the elevator they used earlier. John-117 then experiences a hallucination of Cortana and follows the figure to a control panel. He then activates the panel, finally learning Cortana's plan: the Ark is manufacturing a replacement Halo after the destruction of the previous one. Knowing that the threat of the Flood is undeniably apocalyptic, and that the new ring is unconnected to the rest of the Array, John-117 decides he will activate the new Halo. Needing an Index in order to fire the ring, SPARTAN-117 journeys into the crashed High Charity to retrieve Cortana, keeping his promise and knowing that she still has the Index she acquired from the original Installation 04. Once retrieved, Cortana instructs the Spartan to overload High Charity ' s engines in order to destroy the Gravemind. Thel 'Vadam arrives via Banshee to assist the Spartan in fighting the Flood. The two escape from High Charity before it explodes using a damaged but still flyable Pelican. Spartacus plays halo nation The surviving Sangheili and UNSC personnel return to Earth, leaving only Sergeant Johnson, John-117 with Cortana and the Arbiter to make their way to the new Halo. As they make their way to the new Halo's Control Room, Flood forms arrive via dispersal pods to prevent the activation of the Halo. From here, they quickly discover that Gravemind is attempting to reconstruct itself on the new Halo. As Sergeant Johnson tries to activate the ring, 343 Guilty Spark fires his defensive laser at him after realizing that it will destroy the installation and the Ark. The Monitor then turns against the Spartan and blasts the Arbiter out of the Control Room, leaving the Spartan to destroy Guilty Spark by himself. John-117 successfully destroys the Monitor with the Spartan Laser and tries to mend Johnson. Mortally wounded, Johnson urged the Spartan to send him out "with a bang".

With the Halo activated, John-117 and Thel 'Vadam race towards the frigate Forward Unto Dawn using Johnson's Warthog. With no time to reach the bridge, John-117 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 its firing sequence and damages the Ark, the portal deactivates as the other half of the Dawn containing Chief and Cortana enter it. This causes them to rip off from the other half of the ship and be sent to an unknown area of space far enough from the Halo's blast. However, since they didn't come out of the other side of the portal, they never make it back to Earth.

Back on Earth, Lord Hood holds a memorial service in honor for those who died in the Human-Covenant War, with the Arbiter and many Marines in attendance. With Truth dead, the Covenant defeated, and the Flood wiped out, the long and devastating war is finally over. Though he says he can never forgive the Arbiter for what the Covenant did to the human race, Lord Hood sincerely thanks him for standing by the Master Chief until the end. After the service, the Sangheili return to their home planet.

After the credits, it is revealed that John-117 and Cortana are still alive aboard the rear section of the Dawn, which had apparently torn off before going through the other side of the portal. The SPARTAN floats to a cryo chamber and as he climbs in, Cortana comments "I'll miss you." He replies "Wake me, when you need me." If the last level is completed on Legendary difficulty, the section of Forward Unto Dawn that Cortana and the Chief are aboard is seen drifting towards a Forerunner world.

Gameplay
Halo 3 incorporates many of the gameplay features previously made available in Halo 2, refining the gameplay design and expanding the amount of resources in the sandbox to diversify the gameplay experience. For example, dual wielding has been retained as a feature in both campaign and multiplayer, HUD elements have been repositioned so that they are more prominently available to the players, and boarding vehicles have more varied animations and are more balanced.

The game enhances the core gameplay design by introducing "Equipment" as well as giving players the ability to use support weapons. Equipment is a collection of tools accessible to players to assist them in their objectives. This ranges from a spherical shield that protects players temporarily, a device that drains power from electrical appliances to a device that propels personnel into the air. Support Weapons allows players to wield heavy weapons in a third-person perspective at a slower pace.

Campaign
The campaign in Halo 3 consists of ten levels which tell the story of the final days of humanity and the Sangheili's conflict with the Prophet of Truth's Covenant forces.


 * 1) Arrival - "Brace for impact." (cutscene, tutorial on single player)
 * 2) Sierra 117 - "Rise up. Start the fight."
 * 3) Crow's Nest - "Clear the base, whatever it takes."
 * 4) Tsavo Highway - "Mount up. Get to Voi."
 * 5) The Storm - "Reclaim the city. Make a hole."
 * 6) Floodgate - "Stop the infestation. Find Cortana."
 * 7) The Ark - "Search the waste for the Cartographer."
 * 8) The Covenant - "Breach the barrier. Stop Truth."
 * 9) Cortana - "Cleanse High Charity. Save Cortana."
 * 10) Halo - "Light the ring. Destroy the Flood."

Service tags
The service tag is how players can be identified quickly on the battlefield, instead of the long names and complex number combinations which are not suitable for battle situations that require quick tactical orders or communication. The service tag is comprised of a letter followed by two numbers. A few examples of service tags are K90, C27, A12, S86, D17, and D21.

Certain service tags are disallowed, and entering them will yield the error message "This Service Tag is currently in use by the UNSC." Generally, tags that identify Halo characters, trademarks, or offensive words are disallowed. Such tags include: "I17", "N64", "P52", "A55", "P00", "J00", "F49", "A23", and "T17". "O00" is blocked due to its usage in Temporary Profiles. Anything ending in 00 is blocked.

According to Bungie, as of March 14 the most used Service Tags by players of Halo 3 are, in descending order, O07, M16, I69, P26, S80, N99, F18, H20, I87, and D13.

Armor permutations
There are two player models which players can choose from, the standard SPARTAN model or an Elite model. Each model has several armor permutations which can be combined. All armor permutations do not have any effects on gameplay.

Emblems
An Emblem is a highly customizable image that appears on the right arm of a Spartan and the back of an Elite during multiplayer matches, they are there to give a player an identity for themselves. Halo 3 introduces several new emblems for the player to use along with new backgrounds to further customize that emblem.

Colors
There are ten base and primary colors, each with three shades of one another that are used to customize your multiplayer color and emblem. On the armor detail color, there is a small painted VI most noticeable on Mark VI shoulder.
 * Steel, Silver, and White
 * Red, Mauve, and Salmon
 * Orange, Coral, and Peach
 * Gold, Yellow, and Pale
 * Sage, Green, and Olive
 * Teal, Aqua, and Cyan
 * Blue, Cobalt, and Sapphire
 * Violet, Orchid, and Lavender
 * Crimson, Rubine, and Pink
 * Brown, Tan, and Khaki
 * Black can still be used but, only in Forge or Custom gametypes, as a forced player color under general settings.
 * Zombie a slightly more yellowish version of Green to make players look like zombies. Only available in Forge or Custom gametypes as a forced player color under general settings.

Engine
The game uses an in-house game engine referred only as the "Halo 3 Engine". The unique features in the engine include advanced graphics technologies such as high dynamic range, global lighting and depth of field effects within cutscenes.

Audio
Halo 3 utilises Waves audio plugin which allows audio to be processed in real time as the game engine generates the audio calls.

Matchmaking
Matchmaking is where people can play with and against each other through a specially designed search system and multiple playlists. In matchmaking, EXP and Skill can be earned to raise ranks. Also, on some maps like "Guardian" and "Narrows", various equipment such as the Flare and Radar Jammer have been removed due to balance changes.

Playlists
Playlists are lists of different game variations from free-for-all to team games. They are split into Ranked, Social, Hardcore, Community, DLC, Tournaments and Double EXP Weekends.

Veto
The Veto system is a new addition to Halo 3. In a game, after the map and game type loads for each player, a 10 seconds countdown starts. If the majority of players in the match decide to veto, by pressing the (X) button, before the countdown ends, a different map and gametype from the playlist will be selected to be played on.

If a map and gametype is vetoed by a majority of players, the option to veto will be lost during the next countdown. In some cases, players will see the map and gametype change, but players 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.

Ranks
The ranking system is based on real military ranks. To progress 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 200 EXP but does not have a skill level of 35 will be promoted to Major, Grade 2 upon earning 300 EXP).

Each Officer rank has a "final" grade which is represented by a unique name instead of a number. Gunnery Sergeant also has this feature. Many players judge others that have the grade 4 rank or "gold bars" as a sign of lack in skill, though not necessarily always true. Halo 3 uses the Trueskill system created by Microsoft to determine skill level in ranked playlists.

Custom games
In the Custom Games Lobby, players are given the option to choose the gametypes and maps players have made and want to play with their friends, these include Custom Game types and Map Variants. Unlike matchmaking, custom games do not give EXP.

Standard gametypes

 * Slayer - Kill your enemies. Kill your friends' enemies. Kill your friends.
 * Oddball - Hold the skull to earn points. It's like Hamlet, with guns.
 * King of the Hill - Control the hill to earn points. Earn points to win. It's good to be king.
 * Capture the Flag - Invade your opponent's stronghold, seize their flag, and return it to your base to score.
 * Assault - Carry your bomb to the enemy base, plant it, and defend it until it detonates.
 * Territories - Defend your territory and control the land. Teams earn points for territories they control.
 * Juggernaut - If you meet the Juggernaut, kill the Juggernaut.
 * Infection - The timeless struggle of human versus zombie. If you die by a zombie's hand, you join their ranks.
 * VIP - One player on each team is Very Important. Take down the enemy's VIP for points, but take care of your own.

Custom gametypes
In Halo 3, there are a number of options that can be changed for custom games. By pressing X in the pregame lobby the host can change the default options, to whatever the player chooses and can save the changes when finished by pressing X again to save as custom game type.

Options that can be changed:
 * Damage resistance
 * Shield multiplier
 * Shield recharge rate
 * Immune to headshots
 * Grenade counts (Grenade Regeneration, on or off)
 * Infinite ammo
 * Weapon pickup (Enabled, Disabled)
 * Player speed
 * (25%, 50%, 75%, 90%, 100%, 110%, 125%, 150%, 200%, 300%)
 * Player gravity
 * (50%, 75%, 100%, 200%)
 * Vehicle use (Full Use, Passenger only, None)
 * Motion tracker (off, friendlies only, normal, enhanced)
 * Range (10m, 25m, 75m, 100m, 150m)
 * Indestructible vehicles (On, off)
 * Player forced Colors (Like Black or Zombie)
 * Meaning all players in game will be forced to the color of your choice.
 * Over shields and active camouflage can be given to a certain team/player or everyone on spawn or re-spawn.

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. Players can, however, edit objects, spawn points, weapons, teleporters and properties of objects on the map, etc. While in a forge map, players may start editing maps by press up on the D pad; when a player goes into edit mode they take on the appearance of a Forerunner Monitor similar to 343 Guilty Spark. The player now obtains the ability to spawn weapons, vehicles and objects in-game, as well as move and adjust them. New DLC maps like Sandbox and Foundry will allow a player to make their own map using the amount of objects included in the map. While the forge may not allow as much freedom as other map editors, it makes it easier for a player to make a map with "simple" objects.

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, players can either watch themselves play through an entire mission or match, or use a bird's eye view to see the bigger scope of how the match or mission plays. Players can go anywhere they want, within the limitations of invisible barriers, so that players cannot fly as high as possible or go very far from their character. In multiplayer matches, players can fast forward or rewind the film so that players can relive the parts you missed. Campaign films cannot be rewound for technical reasons. Only the previous 25 games will be saved under the recent films category on the Xbox 360 console. Older films will be deleted.

Clips
When playing a film, players can record a particular part of the film from any angle they want. Doing this allows players to look back at their saved clip without having to watch the entire film. Players, however, cannot record clips of campaign films due to unknown technical reasons. If players are in a party viewing a film, they will not be able to record clips, nor take screenshots. Also, players may find that when viewing a film clip in a party, the film will not load until there is only one player left in the party.

Screenshots
Screenshots can be taken in any sort 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. Screenshots that are favored by many or impress Bungie employees may be uploaded to Bungie Favorites.

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.

Beta and Epsilon
The Halo 3 Beta was a phase in the development of Halo 3, produced by Bungie Studios and organized by Microsoft. A public version of the beta was released to the public for three weeks to give people an early chance to play the game and to test amounts of stress on the servers.

Several months after the Beta was closed down, Bungie released Halo 3 Epsilon, an internal-only Halo 3 build, to Microsoft employees. The Epsilon featured Campaign (both single-player and cooperative gameplay) on the level Tsavo Highway, as well as Forge and multiplayer on six maps: Epitaph, High Ground, Last Resort, Sandtrap, Snowbound, and Valhalla.

Iris
On June 11, 2007, at 10:26AM PDT, the viral marketing campaign for Halo 3 started, with a believed "hacking" of Bungie.net's forums throughout the next several months fans followed the various clues and hints to unlock "servers" which would reveal the final moments of the Forerunners. Cradle of Life: The Cradle of Life is a short flash animation web comic, and is one of the first parts of the Iris campaign.

Believe
Believe was the marketing slogan and campaign for Halo 3 developed by both Bungie Studios and Microsoft. The word "Believe" appears to be honoring the legacy of SPARTAN-117, citing him as a hero of humanity whose brave actions inspired other servicemen of the United Nations Space Command during the final days of the Human-Covenant War. It has been noted that the Believe trailers took place about 50 years after Halo 3's storyline.

Announcement trailer
