Halo 3

Core Gameplay Mechanics

Halo 3 is a first-person shooter where players experience combat on foot and in vehicles. The combat system is built around a sandbox of weapons, grenades, and melee attacks. A key feature from previous games, dual-wielding, allows players to wield two smaller weapons for increased firepower, though this prevents the use of grenades and melee. A visible change from earlier installments is that a player's secondary weapon is now shown on their character model, holstered or slung on their back.

The game introduced new elements to this sandbox. Support weapons are cumbersome two-handed arms like the missile pod or Spartan laser that slow the player's movement but offer greatly increased firepower. Another major addition was equipment, a new class of gear with various one-use effects. Players could carry one piece of equipment at a time, choosing from items like a deployable gravity lift, a bubble shield for protection, a power drainer, or a regenerator to restore shields.

Content Creation and Sharing

Halo 3's most celebrated innovations were its tools for player creation. The Forge is a map-editing utility that allows players to insert, remove, and manipulate game objects like weapons, crates, and vehicles on existing multiplayer maps. Players enter a Forge session and can edit these objects in real time, though a budget system limits the total number of items that can be placed. This allowed for the creation of custom game variants and entirely new gameplay experiences within the official maps.

Complementing Forge was a robust file sharing system. Players could save up to 100 films of their gameplay directly to their Xbox 360 hard drive. These saved films could be viewed from any camera angle and at different speeds. Custom content like these films, screenshots, and Forge-edited map variants could be uploaded to Bungie's official website. Other players could browse this content online and tag it to automatically download to their console the next time they signed into Xbox Live on Halo 3.

Multiplayer Systems and Matchmaking

Multiplayer in Halo 3 supports up to sixteen players via local area network or Xbox Live. Game modes include variations of deathmatch and Capture the Flag. Players had two primary ways to play. They could organize custom games using their own rules and customized maps by inviting friends from their Xbox Live list or using the LAN search feature.

For automated play, the Matchmaking system grouped players of similar skill. Players selected from developer designed playlists, each containing a specific set of maps and game types. Matchmaking used a customized version of the TrueSkill ranking system on a per playlist basis to assess skill. A separate linear measure, called EXP, tracked a player's experience within each matchmade playlist. The game included features to manage the online experience, such as options to mute other players' voice chat directly from the in game scoreboard and provide feedback on player service records.

Campaign Structure and Co-op

The story campaign of Halo 3 can be played alone or cooperatively with up to three other players via Xbox Live or System Link. In a departure from previous Halo games, each player in co-op controls a distinct character. The first player is the Master Chief, the second is the Arbiter, and the third and fourth players control the Covenant Elites N'tho 'Sraom and Usze 'Taham. While their starting weapons differ, all characters have identical abilities.

The campaign includes hidden skulls on each level. When collected and enabled, these skulls modify gameplay in various ways, such as giving enemies extra health, changing in game dialogue, or altering AI behavior. The enabled skulls, combined with the selected difficulty level and the speed of completion, provide multipliers to a player's total score for each level. Reaching certain score thresholds unlocks Achievements, which award gamerscore points.

Story Conclusion

Set in 2552 and 2553, Halo 3's plot concludes the war between humanity and the alien Covenant. Following the events of Halo 2, the Master Chief arrives on Earth in east Africa and reunites with Sergeant Johnson and the Arbiter. The Covenant leader, the High Prophet of Truth, excavates a Forerunner artifact on Earth that creates a slipspace portal. After Truth enters the portal, the Chief and his allies follow.

They arrive at the Ark, a massive Forerunner installation beyond the Milky Way galaxy, where Truth plans to activate all the Halo rings. The parasitic Flood arrives in force, infesting the installation. After forging a temporary truce with the Flood's Gravemind to defeat Truth, the Chief and Arbiter discover the Ark is constructing a replacement Halo ring. To destroy the local Flood threat without wiping out the galaxy, the Chief decides to activate this incomplete ring. In the process, Johnson is killed by the AI 343 Guilty Spark. The Chief activates the ring, causing it to self destruct. He and Cortana escape on the frigate Forward Unto Dawn, but only half the ship makes it back to Earth. The Chief is presumed lost, entering cryonic sleep as his half of the ship drifts toward an unknown planet.

Development Context and Launch

Development of Halo 3 began after Halo 2 shipped. Bungie was openly critical of Halo 2's rushed development and cut content, and viewed the third game as a chance to deliver a complete experience for fans. It was also intended to be the final Halo game Bungie would make before becoming an independent studio. Early development faced challenges, including a lack of clear creative direction after co-founder Jason Jones went on sabbatical and internal conflicts over the story.

The game was officially announced at E3 2006. Microsoft spent $40 million on marketing, which included a multiplayer beta accessible to players who purchased the Xbox 360 game Crackdown. Upon release on September 25, 2007, Halo 3 grossed $170 million on its first day and $300 million in its first week. It sold over 14.5 million copies, making it the best selling video game of 2007 in the United States. More than one million people played on Xbox Live within the first twenty hours.

Lasting Impact and Re-release

Halo 3 was met with widespread critical acclaim. Reviewers frequently singled out the Forge editor and the multiplayer offerings as key features. The game is often listed among the most notable video games of all time. Its success helped drive sales of the Xbox 360 console. The story's conclusion directly set up the events of Halo 4, which was developed by 343 Industries and released in 2012.

The game's longevity was secured through its inclusion in Halo: The Master Chief Collection. This compilation re-released Halo 3 for the Xbox One in November 2014 and for Windows on July 14, 2020, featuring updated visuals and integrated multiplayer services, ensuring continued access after the original Xbox 360 version's online services ended in January 2022.
