However, Jones also noted that the character designers and artists had to make a "living, breathing world" and populate it with interesting characters and places. The game's development which spanned four years brought numerous evolutions and revisions to the character's designs and personalities. Characters were also updated to take full advantage of new graphics technologies; for instance, the Master Chief

. Other Bungie developers would often add input to the progress of characters in Halo, even if they were not working on the game itself. For example, an outside artist, Shi Kai Wang, developed the early concept sketches of what would eventually become the Master Chief. However upon developing a 3D model, the artists decided the Chief looked too slender, almost effeminate, and subsequently bulked up the character. Early Covenant Elites had a more natural jaw rather than the split mandibles they would later sport; at one point, Jason Jones was also insistent about having a tail on the Elites, but this idea was eventually dropped.

Designers decided to hand-key animations, rather than attempt motion capture
Motion capture
Motion capture, motion tracking, or mocap are terms used to describe the process of recording movement and translating that movement on to a digital model. It is used in military, entertainment, sports, and medical applications, and for validation of computer vision and robotics...

. The animators also often videotaped themselves to have reference footage for the movement of game characters. Art Director Marcus Lehto had his wife videotape him "running around a field with a two-by-four" for footage for human marines. By Halo 3, Bungie staff had a special room designed for capturing reference material. Many of the subsequent human character's features were based on Bungie designers, while character animators looked to simian, ursine, insectoid and reptilian features for the various races of the Covenant. The artificial intelligences of the characters was also deliberately limited to make sure they acted realistically to environmental changes and situations.

When the Prophet of Regret retreats from Earth, Keyes orders In Amber Clad to follow; this results in the discovery of Installation 05, another Halo. Keyes, along with Johnson and a squad of Marines, head for Halo's library in order to retrieve the Activation Index and prevent the ring's activation while the Master Chief assassinates the Prophet of Regret; in the process, she and Johnson are captured by the Brute Chieftain Tartarus. As a "Reclaimer," only she or another human can insert the Index into Halo's control panel, and Tartarus attempts to make her do this. When the Arbiter

After the Arbiter engages and kills Tartarus, Keyes successfully removes the Index and prevents Halo from activating, but inadvertently causes all the remaining Halo installations to enter standby mode, enabling the remote firing of these installations from The Ark. In Halo 3, Miranda Keyes returns to Earth and leads the pursuit of the Prophet of Truth through the portal he creates using the artifact buried under New Mombasa, which leads to the Ark. When Sergeant Johnson is captured by the Covenant to activate the installation, she attempts to rescue him, but is killed when Truth shoots her in the back.
