Soon after producing the music for "Myth II", Bungie contracted O'Donnell for several of Bungie's other projects, including the third-person game "Oni". Bungie wanted to re-negotiate the contracts for "Oni" in 1999, which resulted in O'Donnell joining the Bungie team ten days before the company was bought by Microsoft. Salvatori remained behind to manage the business aspect of TotalAudio, which he continues to do. During production Bungie decided that instead of contracting work to O'Donnell, they would hire him. Salvatori remained at TotalAudio to manage the business aspect of the company, and shortly after O'Donnell joined the team, Bungie was bought by Microsoft. Salvatori co-composed the music for "Halo"s sequels—"Halo 2" and "Halo 3"—with O'Donnell, who has called Salvatori one of his musical influences.
