Assassin's Creed's Unity, the upcoming next-gen game, may be getting a subtle upgrade.

Titanfall may be inspired by Assassin's Creed parkour moves, but Titanfall took it one step further with horizontal wall-running. But for Unity, wall-running may be included, according to Gameranx.

Jesse La Flair, a traceur who goes by LaFlairParkour, says it will be in the next game. In the comment section of an instructional parkour video, he said: "What if I told you I may or may not have worked on the NEXT AC and they may or may not have added the ability to Horizontal Wall Run in the game..."

There's at least some basis of truth to this rumor, but there's another rumor flying around on the Assassin's Creed reddit page that may be more fiction than fact. Supposedly, the scrivener Nicholas Flamel will be involved in the game.

Though he's a Frenchman, the timeline doesn't quite add up. Flamel lived in Paris in the 14th and 15th centuries, and the game will take place in the 18th century, so perhaps he is involved in another way.

One of the latest trailers featured an assassin wearing a black hood and watching a public execution from a rooftop. The accompanying video said, "Qu'ils mangent de la brioche [Let them eat cake]! We have been working on the new Assassin's Creed for more than three years and although we weren't quite ready to show you our full vision for a next-gen only AC, it seems Abstergo are trying to force our hand! So here's a true first look at in-game footage from Assassin's Creed Unity. Stay tuned - we'll have many more exciting details for you in the months ahead!"

The game will be released in December.
