There's been quite a bit of speculation about how BioWare's Destiny 2-styled online shooter Anthem will tell a single-player story contained within a multiplayer world, particularly since epic tales of solo heroism have historically been BioWare's bread and butter. Casey Hudson's "mid-summer update" on the BioWare Blog reveals a little bit about how the studio is approaching the task through a system called "Our World, My Story." 

"[Our World, My Story] is one of the most innovative things about Anthem," Hudson wrote. "In the dynamic open world, everything is experienced in real-time by all Anthem players—day/night, weather, and world-scale events that shape the ongoing narrative of the setting. This is 'our world,' which we share as a player community."
