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 published by Microsoft. Halo 3 was released on September 25th, 2007 only for the Xbox 360.

Halo 3, is the sequel and concluding part to Halo 2 which fully wraps up the current story arch 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, thus activating the Halos, which would result in the extermination of all 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, filled in the missing segments between Halo 2 and Halo 3 on Earth.

Halo 3 was released on the long-awaited September 25h 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 mild 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. However the UK Release is rated 15 by the BBFC which means it is slightly easier to purchase.

Exactly like its predecessors, Halo 3 was a prosperous, record-breaking game. Accompanied by its record-breaking 1.7 million pre-orders in the U.S., few expected it not to break records. 24 hours after release, Halo 3 had generated a record-breaking $170M in the U.S., which later was beaten by Grand Theft Auto IV's worldwide $310M. Microsoft never released 24-hour sales number, but it is estimated to have sold in the region of 2.4 - 2.5 million copies within 24 hours of availability in the U.S., with that number increasing to 3.3 million units 12 days after release. As of November 17, 2008 Halo 3 had reportedly sold 8.8 million copies worldwide.

Plot
The storyline begins several days after the events of the Halo 2 era. John-117 - the Master Chief, after hitching a ride on the Prophet of Truth's Dreadnought, 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, but was presumed dead until the Master Chief said "Yeah, you're not." in response to Sergeant Major Johnson telling the Marines that "We aren't leaving him here." . After the short cutscene, the Master Chief sees one of his old enemies, The Arbiter, and runs towards him, pistol in hand, but Johnson holds the Chief back, explaining to him that the Arbiter is their ally in the war now, as they share a common enemy [The Brutes/Flood]. The group then 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, Avery 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 led by a Gravity Hammer wielding Chieftain. 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, believed to be an old NATO base, 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 plan is to have the Master Chief with a small group of marines to punch a hole in Truth's anti air defense, so that Lord Hood can initiate a low level strike on the artifact. Their planning is quickly interrupted when power is cut and 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 a 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 the 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 parasitic species, had broken through the Elite's Quarantine of High Charity and arrived suddenly via slipspace and crashes into 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 Faction which broke off from the entire Covenant during Halo 2/ Halo 3 (somewhere right after Halo 2 era), lead by Shipmaster Rtas 'Vadum, arrives at Earth and assists the struggle against the 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 a 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, losing a few comrades in the making. 343 Guilty Spark (the Elites refer to him as the Oracle) arrives by a Separatist Phantom, and insists that he take Cortana somewhere where he can make repairs, claiming that now his Installation has been destroyed he now must follow his second function of helping the Reclaimers, so decides 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 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 Gravemind is coming to Earth on the former Covenant city, High Charity, and 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. Lord Hood stays on Earth to fight the remaining infected with some UNSC marines and the rest of the UNSC Army. On the other side of the portal, 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, with Rtas 'Vadum stating "Then it is an even fight". After landing on the structure, Guilty Spark helps lead Master Chief and the UNSC armored 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. Miranda Keyes then 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 via slip-space and crashes onto the Ark, releasing Flood Dispersal Pods as it falls. Spark insists that he must assess the damage that High Charity did to the Ark, so the Arbiter and Elites leave the UNSC to protect Spark from 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, 343 Guilty Spark and the Arbiter return, but then 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 fires seven shots at her spine 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, after a short confrontation with Truth over the truth of the Halos, executes Truth with his Energy Sword, while the Master Chief deactivates all the Halos, and Johnson is seen walking towards the Pelican with the body of Keyes. After the rings are stopped, however, the Gravemind betrays them. Johnson attempts to escape with the Pelican of Commander Keyes, and he escapes, 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 replacement 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 a Banshee and helps the Chief fight the Flood. They find a Pelican, which had presumably crashed when 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 flee 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 the Halo. However, Guilty Spark realizes that this will destroy his new ring because it is not fully ready yet, as well as the Ark. Guilty Spark becomes rampant, and fires his defensive laser at Johnson as he tries to activate the ring. Guilty Spark soon turns on the Master Chief and locks the Arbiter out of the room. leaving the Spartan to destroy Spark himself. 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 made it through.

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 destroyed, 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 the to human race, Lord Hood sincerely thanks him for standing by the Master Chief until the end. Everyone thinks the Chief is dead. After the service, Shipmaster Rtas 'Vadum, 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. Just after this you see the camera zoom in to the memorial where the number 117 is scratched onto the front. Then credits roll.

After the credits, it is revealed that the Master Chief and Cortana are still alive on-board the rear section of the Dawn, which had apparently torn off before going through the portal; 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 last level is completed on Legendary difficulty, the section of Forward Unto Dawn that Cortana and the Chief are aboard is seen drifting towards an unknown Forerunner planet.

Cold Storage
This map is downloadable through Xbox Live Marketplace for free and is the 7|seventh downloadable map for Halo 3. It released on 07/07/08, Bungie Day, as a free gift to the entire Halo 3 community around the world.

Mythic Map Pack
These new maps have been mentioned or announced by Bungie, all with varying degrees of information. The following maps below have been confirmed by Bungie to be together in the Mythic Map pack. It was confirmed by Bungie that Assembly, Sandbox and Orbital are going to be shipped with the Limited Edition of Halo Wars. They will be added to the Xbox Live Marketplace shortly after. Special online competitions are also being held to get the first three maps free. As to the other three Mythic Maps, they will be included in the shipping of Halo 3: ODST.
 * Assembly
 * Orbital
 * Sandbox

Service Tags
The Service Tag is how you and your team 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 and D21 When certain specific Service Tag coding is entered for example I17 (117) an error message will appear stating "This Service Tag is currently in use by the UNSC" and to choose another. Another error message 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. Similar error messages are shown if you put in "A55", "N00", "P00", "F00", "J00" and "T17" as they are offensive references.

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 D13.

The chances of two people having the same service tag on Xbox Live is 2574 to 1.

 * 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

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. You have a highest skill which cannot be taken away, but your current skill level can decrease if you play poorly in that variant.

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. The Community Playlist returned on July 7, 2008 with the release of the free map Cold Storage.

Ranked
The Ranked playlists are the more serious playlists. Skill can be raised and EXP can be gained.
 * Lone Wolves - Various gametypes free for all up to six players.

 * Team Objective - Objective based gametypes with two teams of three to four players.
 * Team Doubles - Slayer based gametypes with two teams of two players.
 * Squad Battle - Various gametypes with two team of six designed to fill some of the void left by excising Ranked Big Team Battle from the Halo 3 Playlists.

Social
The Social playlists are the more relaxed playlists. EXP can be gained and guests are allowed. The DLC Playlists have now been deleted. Now it is two new social playlists instead:
 * Rumble Pit - Various gametypes free for all up to eight players. Have now been updated to DLC.
 * Big Team Battle - Various gametypes with two teams of five to eight players. This playlist has been expired.
 * Social Slayer - Slayer based gametypes with two teams of five players.

Veto
The Veto system is new for the Halo franchise. Vetoing a map and game type is a very useful thing these days. In a game, after the map and game type loads for each player, a 10 second 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. (Note that not all playlists have the veto option).

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

If a map and gametype is vetoed, the option to veto will be lost during the next countdown. Sometimes you will see the map and gametype 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 a few gametypes, such as Grifball.

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

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.

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, teleporters 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. You can also get more forging items if you get any of the new map packs from Bungie.

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. If it doesn't say save changes simply save it as a new variant (naming it differently than your original) and delete your original when you return to the lobby.

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 use 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. (Note: If you haven't received the February Auto-Update, after your first 25 film slots are filled, about 1 out of the 3-5 films in future will only be saved due to a glitch. The AU fixes this glitch, but not entirely however, as all games played on Local area Network on the 360 still mostly have this problem.)

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 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. If your screenshot is favored by many and also Bungie employees they may put it on Bungie Favorites. The favorites link can be found here

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 picks up his helmet and then he uses a Bubble Shield to defend himself from an incoming Wraith's 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.

Versions
Halo 3 was released in three separate versions. The Standard Edition contains the game disc, manual, and a small poster with the game's control-map and artwork.

The Limited Edition, contained in a metal case, contains the game disc, manual, poster, interactive Xbox 360 bonus disc with several featurettes, and a hard cover bound "Bestiarum", which is a collection of information and art covering the species, cultures, and civilizations of Halo 3.

The final version was marketed as the "Legendary Edition", which contains the game disc, manual, poster, interactive bonus disc, Bestiarum (on one of the DVD discs), Legendary DVD containing special content exclusive to the Legendary Edition, and a scale replica of the Master Chief's helmet as a case for the three discs. The slip-cover packaging unfolds into a large heavy-stock poster of Master Chief. Gamestation stores in the UK also offered a limited edition Master Chief figurine only available to the first 1000 pre-orders.

Halo 3: ODST
ODST is a campaign extension for Halo 3. The trailer opens up on a security camera in New Mombassa. It shows several scenes of destruction before turning upward and showing several HEV Pods fall towards the city. It first appeared on Bungie.net. It now has circulated through YouTube and other video hosting websites. You take control of an ODST soldier, and survive through the Covenant-controlled New Mombassa. Campaign will be similar to normal Halo games, but since you are no longer a Spartan nor Elite, you will have to choose your battles carefully. Bungie recently stated that the expansion is set to be released in the Fall of 2009.

Reviews and Reaction
Halo 3 has received mainly positive reviews from both the online gaming sites and country specific magazines.
