85% of Assassin’s Creed’s plot is already mapped out according to lead writer Darby McDevitt.
Speaking in the latest issue of Xbox World 360 Magazine he says;
“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, 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.
“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?”
