Bungie has revealed a “multi-year narrative plan” for Marathon. Creative director Julia Nardin explained that the team has the overall story direction mapped out but will keep it flexible to incorporate player feedback She stated, “We know where we want to take the story over the next few years, but I don’t want to say it’s completely ‘locked in’ because it’s important to us that our players be able to help shape it.” The backstory of what happened to Tau Ceti is “locked,” with more clues to be revealed over time as the story evolves. “It’s also important that players can jump into Marathon at any time. They’ll always be able to uncover the mysteries of Tau Ceti’s past while experiencing its present. We want every season to be a new entry point, and for new players to be able to understand what’s going on regardless of how long we’ve all been running.”
