In a way, director Ridley Scott's Halo-themed project, dubbed Nightfall, brings Microsoft's tentpole shooter franchise full circle. Master Chief's galaxy-spanning exploits owe a giant debt to the filmmaker's iconic tale of deep-space horror, Alien, and now Scott is helping establish where the franchise goes on the Xbox One. As 343 Industries head Bonnie Ross said during my meeting at E3 this week, working with him "kind of upped the bar" on the series, especially compared to 343's last attempt at live-action, the Halo 4 lead-in Forward Unto Dawn. "Hopefully we get better each time," she said. Nightfall tells the origin story for Agent Locke, a character Ross said plays a "pivotal role" in Halo 5: Guardians. As far as story, that's as much as we know so far. Ross isn't sure how many episodes Nightfall will span, but said that there will be five of them leading into Halo 5's beta timeframe.
