'Halo: Nightfall' Release Date This Year: Watch The Trailer Here [VIDEO]

The "Halo: Nightfall" trailer is finally here. Director Ridley Scott unveiled a teaser for the live-action series based on the popular gaming franchise during Comic-Con in San Diego on Thursday. The series will debut as streaming video this year for Xbox One and Xbox 360 users, as well as on Windows 8.1 devices.

“Halo: Nightfall” will consist of five episodes that will launch on a weekly basis.

Microsoft Corp. (NASDAQ:MSFT) explained the premise of the series on the Xbox site on July 24.

Taking place between the events of Halo 4 and Halo 5: Guardians, Halo: Nightfall follows the origin story of legendary manhunter Jameson Locke (Mike Colter) and his team as they are caught in a horrific terrorist attack while investigating terrorist activity on the distant colony world of Sedra. Led by Locke, the Office of Naval Intelligence (ONI) agents are forced to coordinate with a Sedran commander with a remarkable history and deep-rooted mistrust of ONI. As the plot unravels, they’re drawn to an ancient, hellish artifact where they’re forced to fight for their survival, question everything, and ultimately choose between their loyalties and their lives. Agent Locke is a new character in the Halo universe poised to play a major role in Halo 5: Guardians releasing on Xbox One in 2015.

During its Comic-Con panel in San Diego, Scott addressed the audience, explaining that “Nightfall” will be his first venture into the realm of video games. He also had the help of Kirkland, Washington-based developer, 343 Industries, the same company working on 2015’s “Halo 5: Guardians.”

“In science fiction, we're always searching for new frontiers. We're drawn to the unknown,” Scott said. “With Halo: Nightfall, we're pioneering a new medium in terms of interactive storytelling on Xbox. It’s going to be fun for long-time fans to see how the worlds come together with an ambition to attract new fans along the way with what we’ve created."

“Halo 5: Guardians” was confirmed for a 2015 release in May, along with the announcement of “Halo: Nightfall” and a Steven-Spielberg-produced live-action television series.

“Halo 5: Guardians” is a bigger effort than “Halo 4.” That applies to the content and scope of the game, as well as the technology in what’s now a brand new and more powerful engine,” Bonnie Ross, general manager at 343 Industries said on May 16. “Certainly there are some core elements carried over from prior games, but we’ve invested a huge effort in retooling our tech to take full advantage of the Xbox One’s hardware and ecosystem to create worlds and experiences worthy of next-gen.”

This will be the first installment since 2013’s “Halo: Spartan Assault,” a third-person shooter set in the timeframe between “Halo 3” and “Halo 4.” The title received mixed reviews. “Halo 4” launched for the Xbox 360 in 2012 and grossed $220 million on its launch day and $300 million during its opening week, setting a record for the Microsoft franchise.
