Halo 5: Guardians

Halo 5: Guardians, announced simply with the title Halo and commonly referred to as "Halo Xbox One" prior to the unveiling of its official title, is the upcoming ninth installment in the Halo franchise. It is the second game in the Reclaimer Saga and continues the story of the Master Chief. Originally alluded to in a teaser trailer shown at Microsoft's E3 Media Briefing on June 10th, 2013, Guardians was officially announced on May 16, 2014. Exclusive to the Xbox One, the game is in development and is set to be released in Fall 2015.

Development
In her formal announcement of the game on May 16, 2014, 343 Industries General Manager Bonnie Ross describes Halo 5: Guardians as a bigger effort than the preceding Halo 4 in terms of the content and scope of the game as well as the technology underpinning it. The game's engine is said to have been completely retooled to take full advantage of the Xbox One's hardware and ecosystem. Ross states that Halo 5 will incorporate lessons the 343 Industries team learned from Halo 4 with regard to technology, performance, aesthetics, and scale in response to feedback received from the fan community. She also mentioned that the game will run at 60 frames per second and will feature dedicated servers.

E3 2013 teaser
In their E3 2013 conference, Microsoft showed a teaser trailer intended to showcase the future direction of the Halo franchise on the Xbox One. Rather than announcing Halo 5 in particular, the trailer announced the presence of the Halo franchise on the new console, set to debut in 2014 with an unspecified Halo title.

The teaser opens with a hooded figure journeying through a desert on an alien world. The figure, revealed to be John-117 clad in battered MJOLNIR armor, clutches Cortana's empty data crystal chip as he encounters an enormous Forerunner machine rising from the sand.
