Assassin's Creed: Revelations is already slated for launch on November 15, but one of the leading developers working on the series from Ubisoft has said that there's more universe lore to be delivered to players although 85 percent of the game story has already been mapped out.

Speaking to the Xbox World Magazine Darby McDevitt, who is the lead writer working on the Assassin's Creed franchise, has stated, “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.”

He added, “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.”

The lead writer says that team is still debating internally exactly how it plans to deliver the last pieces of the story, with the possibilities being another stand alone game, a handheld title, probably for the new Vita, a comic book or a Facebook-based experience.

The lead writer has also said that while most of the elements of the story are locked in place those contributing to it can still change significant elements as long as they come up with cool ideas or twists.

Revelations is set to deliver a plot that shows the main connections between the main characters of the series: Altaïr ibn La-Ahad, Ezio Auditore da Firenze and Desmond Miles.

The developers at Ubisoft Montreal have also said that they have refined all the gameplay mechanics and introduced some new, surprising ones.

Assassin's Creed: Revelations will be released on the PC, the PlayStation 3 and the Xbox 360.
