Halo 3: ODST is a 2009 first-person shooter video game developed by Bungie and published by Microsoft Game Studios. The fifth installment in the Halo franchise, it was released on the Xbox 360 in September 2009. Players assume the roles of United Nations Space Command Marines, known as "Orbital Drop Shock Troopers" or ODSTs, during and after the events of Halo 2 and before the events of Halo 3. In the game's campaign mode, players explore the ruined city of New Mombasa, to discover what happened to their missing teammates in the midst of the Covenant alien invasion of Earth. In the "Firefight" cooperative multiplayer option, players battle increasingly difficult waves of enemies to score points and survive as long as possible. The game also contains the entirety of Halo 3s multiplayer on a separate disc.
Despite reacquiring independence from Microsoft in 2007, Bungie was contractually committed to two more Halo games for the publisher. ODST was initially conceived as a downloadable story expansion for Halo 3 to produce in the lull between the game's completion and Halo: Reach (2010). Instead of featuring recognizable characters such as armored protagonist Master Chief, the developers focused on the ODSTs. Story director Joseph Staten penned a detective story utilizing film noir designs, settings, and characters. Composer Martin O'Donnell abandoned his previous Halo themes to create a quieter, jazz-influenced sound. During development, the planned expansion grew in scope to that of a full-sized game. Release marketing for the game included a tie-in comic, live-action trailers, and print and web advertisements.
Upon release, ODST became the top-selling Xbox 360 game worldwide. The title received generally positive reviews from critics, who praised the atmosphere, music, and story approach. Reviewers were divided on whether the relatively short campaign and included extras were enough to justify the game's price tag. The game was the top-selling title in the United States in September 2009, and sold more than 3 million copies worldwide. Softpedia, Time, and Wired were among publications that declared the game one of the year's best. The single-player campaign was re-released as an add-on for the Halo: The Master Chief Collection for Xbox One in 2015. The campaign was added to The Master Chief Collection on Windows in 2020 alongside the Firefight multiplayer being made available on both platforms. The game would receive a crossover with Helldivers 2, developed by Arrowhead Game Studios and published by Sony Interactive Entertainment, in 2025, with weapons and armor from ODST being added as downloadable content.
Gameplay
Halo 3: ODST is a shooter video game with most gameplay taking place from a first-person perspective. The game features an open world environment in the updated Kenyan city of Mombasa, referred to as New Mombasa. Although the gameplay of ODST bears a strong resemblance to that of previous Halo titles, the player does not assume the role of the enhanced human supersoldier Master Chief, protagonist of Halo 3. Instead, the player controls human soldiers known as "Orbital Drop Shock Troopers" or ODSTs. Since ODSTs do not possess the Master Chief's advanced armor and reflexes, they cannot jump as high, move as fast, or survive large falls. Instead of the Master Chief's damage-absorbing energy shield, the game uses a recharging stamina mechanic. After the player sustains damage, the screen flashes red and the stamina score decreases. If the player receives additional damage before the stamina can recover, the player's health is reduced. Loss of all health causes the player character to die and restart at the last saved checkpoint. Medical packs scattered around the game environment can restore the player's health. The player's head-up display (HUD) includes a "VISR" mode that outlines enemies in red, allies in green, and items of interest in either blue or yellow.
The game's Campaign mode may be played alone or cooperatively with a maximum of three additional players. As a lone human soldier known as "the Rookie," the player's goal is to discover what happened to his missing teammates. After finding a piece of evidence left behind, such as a sniper rifle hanging from a power line, the player will enter a flashback mission, where they assume the role of the missing soldier six hours earlier. After the player has found the first piece of evidence, the choice of where to go next is left open; campaign levels may be played in any order.
In the multiplayer matchmaking, ODST includes Halo 3s multiplayer game modes contained on a separate disc. The offering contains 21 multiplayer maps released for Halo 3 as well as 3 additional maps titled Citadel, Heretic, and Longshore. Along with the Halo 3 maps, ODST includes a version of the Forge map editor—a utility that allows player customizations of multiplayer levels.
ODST contains a timed cooperative survival game mode called Firefight, where players take on increasingly difficult waves of enemies. Firefight can be played with up to three other players via networked consoles (System Link) or Microsoft multiplayer service Xbox Live, or up to two players on the same console in splitscreen mode. Players start Firefight with only the Rookie as a playable character; completing the campaign mode unlocks other characters and maps. Players are awarded medals for making special kills, and individual and team scores are tracked throughout the games. Inside Firefight, players have a shared pool of seven lives, which are replenished after completing five rounds. Adding to the difficulty are modifiers called "skulls", which give enemies new abilities or a handicap to the player – the "Catch" skull, for example, causes enemies to throw greater numbers of grenades. Each of the first three rounds in a set activates a different skull. On the fourth set, all skulls are activated and the players must survive 60 seconds.
Campaign
Setting and characters
ODST takes place in the 26th century, when humans under the command of the United Nations Space Command (UNSC) are locked in a war with a theocratic alliance of alien races known as the Covenant. During the events of the 2004 video game Halo 2, the Covenant discover the location of Earth and launch an assault on the city of New Mombasa in Africa. Though the UNSC manages to repel most of the fleet, a large ship hovers over the city, depositing an invasion force. The ship eventually retreats via a slipspace jump, creating a massive shockwave. While the rest of Halo 2s storyline follows the ship to an ancient installation similar to the first Halo, ODST focuses on the aftermath of the shockwave, while the Covenant still occupy the city.
During the game, the player can unlock audio files to an additional narrative called "Sadie's Story", which tells the story of a civilian girl caught in the initial stages of the Covenant invasion and her quest to find her father. The tale can also provide useful information for the player during the game, such as helping to locate hidden caches of weapons.
The game's protagonist is the unnamed Rookie, a new member of a group of Orbital Drop Shock Troopers. Troopers, known as ODSTs or Helljumpers, often deploy in small, one-man Human Entry Vehicles (HEVs), referred to in-game as Single Occupant Exo-Atmospheric Insertion Vehicles (SOEIV), launched from spaceships in the upper atmosphere. The Rookie is assisted in finding his teammates by Mombasa's city maintenance AI, called the Superintendent or Vergil. The Rookie's teammates are Buck, Dutch, Romeo, Mickey, and Dare. The lattermost is a UNSC Office of Naval Intelligence (ONI) agent in charge of the squad's operation.
Plot The game begins with Dutch (Adam Baldwin), Romeo (Nolan North), and Mickey (Alan Tudyk) discussing the Covenant Supercarrier above New Mombasa, with the Rookie asleep nearby. Buck (Nathan Fillion) arrives and introduces Dare (Tricia Helfer). Romeo wakes the Rookie and the team enter their HEVs and drop through the atmosphere; at the last minute, Dare changes their trajectory to miss the ship due to a classified mission she has for the team. The Covenant ship enters slipspace with a UNSC ship that can be seen pulling alongside it, sending a shockwave toward the ODSTs; the Rookie's pod collides with Mickey's and crashes into a building on the ground, knocking him unconscious for six hours. He awakens and proceeds to find clues as to what happened to his squadmates.
Buck makes a rough landing after the drop and fights through Covenant forces to find Dare. However, Dare has vanished without a trace when he arrives at her drop pod, leaving behind only her helmet which is later found by the Rookie. Buck finds Romeo instead and the two resolve to find the others and leave the city. Dutch drops near a nature preserve and helps Marines fighting there. Mickey commandeers a tank and fights his way along a Mombasa boulevard. Meeting up with Dutch, the two defend an ONI base from the Covenant, destroying the facility to keep it from being captured. They are evacuated by a police dropship and make contact with Buck, arranging a rendezvous at police headquarters, but are shot down. Buck and Romeo rescue Dutch and Mickey, but Romeo is seriously wounded. The squad hijacks a Covenant dropship, but instead of leaving the city, Buck decides to have them turn back and find Dare, having realized that Dare has continued her classified mission on her own.
Back in the city, the Rookie is assisted by the Superintendent Vergil, the city's maintenance AI. The Rookie receives a distress call from Dare and locates her in the city's underground tunnels. The two reach the Superintendent's data core, which possesses information on something the Covenant is looking for underneath the city. Inside the core, they discover a Covenant Engineer that has combined the Superintendent into itself. Dare explains that the Engineers are "biological supercomputers" that have been enslaved by the Covenant, and the one they found wishes to defect to the humans; with the Engineer's information on the Covenant combined with the Superintendent's data, Dare's mission changes from downloading the Superintendent's data to escorting the alien to safety. The Rookie, Dare, and the Engineer reunite with Buck and fight their way out of the city where they reunite with the rest of the squad. As they fly away in the hijacked dropship, the squad watches as Covenant ships destroy New Mombasa and excavate a massive alien artifact.
In the epilogue, one month after the events of the campaign, the ODST squad has been keeping guard over the Engineer. Sergeant Major Avery Johnson arrives, informing the Engineer that he intends to ask it everything it knows about the Covenant—and what they are looking for. Hating the Covenant as much as the humans do, the Engineer lights Johnson's cigar in a sign of agreement. If the campaign is completed on the Legendary difficulty level, a scene shows the Prophet of Truth overseeing the excavation of the Forerunner artifact buried beneath the Superintendent's data core.
Development
Design Much of ODSTs development team started work on director Peter Jackson's Halo Chronicles video game during the production of Halo 3. However, the failure of a Halo film adaptation and the subsequent cancellation of Chronicles meant a sizable team no longer had a project. Around the same time, production for Halo: Reach began, and Bungie realized that there was a window of time for the studio to create a new product, what producer Curtis Creamer described as a two-to-three-hour "mini-campaign". After looking at the proposal and the budget, studio head Harold Ryan gave the go-ahead.
