Halo 4

Halo 4 is a 2012 first-person shooter video game developed by 343 Industries and published by Microsoft Studios for the Xbox 360 video game console. The seventh video game installment in the Halo franchise, the game was released worldwide in November 2012. Halo 4's story follows a cybernetically enhanced human supersoldier, Master Chief, and his artificial intelligence construct Cortana, as they encounter unknown threats while exploring an ancient civilization's planet. The player assumes the role of Master Chief, who battles against rogue remnants of the military alliance of alien races known as the Covenant and warriors of the Forerunner empire known as the Prometheans. The game features a selection of weapons, enemies, and game modes not present in previous titles of the series.

Development of Halo 4 began in 2009 and continued until September 2012. Halo 4 is 343 Industries' first original title within the Halo series—previously, development of the main series was undertaken by Bungie, the creator of the franchise. In the developmental process, 343 Industries decided to explore the Forerunner fiction within the Halo universe, leading the team to design a new setting, enemies, and main antagonist. Existing characters and assets received visual overhauls and motion capture was used for animation within cutscenes. A goal for Halo 4's story was to incorporate more human elements; to achieve this, the developers chose to delve more deeply into the relationship between the two protagonists, Master Chief and Cortana. Several external studios assisted 343 Industries with developing Halo 4, and over 350 people worked on the game in total.

Halo 3

Halo 3 is a 2007 first-person shooter video game developed by Bungie for the Xbox 360 console. The third installment in the Halo franchise, the game concludes the story arc begun in 2001's Halo: Combat Evolved and continued in 2004's Halo 2. The game was released on September 25, 2007, in Australia, Brazil, India, New Zealand, North America, and Singapore; September 26, 2007, in Europe; and September 27, 2007, in Japan. Halo 3's story centers on the interstellar war between twenty-sixth century humanity and a collection of alien races known as the Covenant. The player assumes the role of the Master Chief, a cybernetically enhanced supersoldier, as he battles the Covenant. The game features vehicles, weapons, and gameplay elements not present in previous titles of the series, as well as the addition of saved gameplay films, file sharing, and the Forge map editor—a utility which allows the player to perform modifications to multiplayer levels.

Bungie began developing Halo 3 shortly after Halo 2 shipped. The game was officially announced at E3 2006, and its release was preceded by a multiplayer beta open to select players who purchased the Xbox 360 game Crackdown. Microsoft spent $40 million on marketing the game, in an effort to sell more game consoles and broaden the appeal of the game beyond the established Halo fanbase. Marketing included cross-promotions and an alternate reality game.

Halo: Reach

Halo: Reach is a first-person shooter video game developed by Bungie and published by Microsoft Game Studios for the Xbox 360 home video game console. The sixth installment in the Halo series, Reach was released worldwide in September 2010. The game takes place in the year 2552, where humanity is locked in a war with the alien Covenant. Players control Noble Six, a member of an elite supersoldier squad, when the human world known as Reach falls under Covenant attack.

After releasing Halo 3 in 2007, Bungie split into teams to develop two different games—what would become Halo 3: ODST and Reach. The developers decided to create a prequel to the original Halo game trilogy, freeing themselves from the obligation of addressing old story threads. As the game would take place on a human world doomed to be destroyed, they focused on making the environment a character unto itself. Longtime Halo composers Martin O'Donnell and Michael Salvatori returned to compose Reach's music, aiming for a more somber sound to match the story.

Halo 2

Halo 2 is a 2004 first-person shooter video game developed by Bungie Studios. Released for the Xbox video game console on November 9, 2004, the game is the second installment in the Halo franchise and the sequel to 2001's critically acclaimed Halo: Combat Evolved. A Microsoft Windows version of the game was released on May 31, 2007, developed by an internal team at Microsoft Game Studios known as Hired Gun. The game features a new game engine, as well as using the Havok physics engine; added weapons and vehicles, and new multiplayer maps. The player alternately assumes the roles of the human Master Chief and the alien Arbiter in a 26th-century conflict between the human United Nations Space Command and genocidal Covenant.

After the success of Combat Evolved, a sequel was expected and highly anticipated. Bungie found inspiration in plot points and gameplay elements that had been left out of their first game, including multiplayer over the Internet through Xbox Live. Time constraints forced a series of cutbacks in the size and scope of the game, including a cliffhanger ending to the game's campaign mode that left many in the studio dissatisfied. Among Halo 2's marketing efforts was an alternate reality game called "I Love Bees" that involved players solving real-world puzzles.
