Antonini and Feldman knew the one thing they had to get right from a fan's perspective was their portrayal of the iconic Master Chief. Antonini said a representative from 343 was with them throughout the shooting process and was able to answer questions and point out details to keep them on the right track.

"What we try to do with our extended fiction is create a kind of 'history' for the universe, from which we can draw ideas, scenarios, characters and events, and connect those to the game in meaningful ways," said Frank O'Connor, franchise development director at 343 Industries.

"The beauty of this approach, when we get it right, is that for fans of that extended fiction, both the game and the related stories end up having more resonance and meaning. But for folks who simply play the games, the story of the game feels like it comes from a richer, deeper foundation."

Antonini said they had access to the developer's art department to represent the imposing Master Chief with an accuracy that fans would appreciate.

"This was an area we knew we couldn't veer in any way shape or form, and we'd be crazy to," Feldman said. "We had to make the best, most authentic Master Chief gear that you could make."

Daniel Cudmore, the actor selected for the beloved role, is an imposing presence on the screen. Cudmore also does all the stunts and action scenes in the Web series.
