Forget about who watches the watchmen; the burning question in Ubisoft's upcoming last-gen console title Assassin's Creed Rogue is, "Who assassinates the Assassins?" Here to answer that question is Shay Patrick Cormac, a former Assassin who considers himself to have been betrayed by his former brothers-in-arms and joins the Templars as part of a quest for revenge against those who wronged him.

Along the way he encounters Haytham Kenway, the middle child of Assassin's Creed III and Assassin's Creed IV: Black Flag, who appear to play a substantial supporting role in Assassin's Creed Rogue's storyline. In addition to expanding upon the Kenway saga, the second of Ubisoft's new Assassin's Creed titles for 2014 will also continue the naval gameplay from the previous two games in the series, while Assassin's Creed Unity returns to dry land with a story set during the French Revolution.

A new trailer for Assassin's Creed Rogue has now been released, featuring a mix of gameplay and cinematics in a range of different locations. The trailer also reveals that Adéwalé, Edward Kenway's old friend and first mate, will be featured in the game as one of Shay's enemies. Since Adéwalé's fate has yet to be established in the series' canon, it wouldn't be surprising if he ends up perishing at the hands of the player in Assassin's Creed Rogue.

At another point in the trailer it also looks like Shay is fighting a younger version of Achilles Davenport, Connor Kenway's mentor from Assassin's Creed III. This scene may take place during the purge of the Colonial Assassins orchestrated by Haytham Kenway. If it is Achilles then players can at least be safe in the knowledge that they won't have to kill the poor old guy.

Shay's motivation is hardly groundbreaking within the larger context of video game plots (vengeance against former allies is a stock trope of the action genre) but it certainly puts an interesting twist of the Assassin's Creed franchise, which has so far been fairly strict about putting players firmly on the side of the Assassins and treating the Templars as the enemies. There have, however, been plenty of hints to suggest that the Assassins are far from saintly and the Templars aren't just Saturday morning cartoon villains, so there's plenty of potential for an eye-opening narrative in Assassin's Creed Rogue.

Assassin's Creed producer Karl von der Luhe has previously said that fans of the franchise will be thankful to have two major releases within a week of each other, but it's entirely possible that a lot of players may end up buying only one of the games. Between Assassin's Creed Unity and Assassin's Creed Rogue, which game do you think looks more appealing?

Assassin's Creed Rogue will be released for PS3 and Xbox 360 on November 11, 2014.
