There’s always room for a ”cool new story” if it ”sits deep within the narrative,” but otherwise events are ”planned out.” Altair’s has been ‘completed’ for two years.
”We have about - to give it a rough estimate - 85 percent of the Assassin’s Creed lore mapped out, but new things always happen along the way,” said Ubisoft’s lead writer Darby McDevitt, in an interview with Xbox World 360 magazine.
”…if a writer comes up with a cool new story which sits deep within the narrative, this might end up changing things. But we do have things planned out.”
”Altair’s complete story arc has been mapped out for two years, and Ezio’s story in Revelations was being conceived and planned when the team started working on Brotherhood,” continued McDevitt.
”So we’ve known the end of Ezio’s story for some time - it’s just a matter of working out how we present that: do we do it in a game? In a comic book? In a handheld game? In a facebook game?” Ezio’s story comes to a close in Revelations and in a short film Embers.
Assassin’s Creed: Revelations releases on Xbox 360, PS3 and PC November 15th.
