The roguish sorts at Ubisoft now offer a couple of new trailers from Assassin's Creed Unity for our viewing pleasure. The UbiBlog has an Arctic Naval Gameplay Walkthrough trailer which shows one of the game's less probable environments, saying: "In the North Atlantic seas sheets of ice offer new areas for exploration, but also new threats and challenges to your sailing abilities. And as if the ice and seas themselves didn't offer enough danger you’ll be faced with cunning enemies using new tactics to send you to a frozen grave." They also have a river valley land gameplay walkthrough trailer they describe thusly: "In this walkthrough commented by Game Director Martin Capel, you’ll learn about naval gameplay in the river valley and get a look at Shay’s new weapons and abilities like the deadly air rifle and its various types of ammunition and Shay’s “Eagle Sense” which allows him to locate, avoid, or eliminate Assassins lurking in the shadows."
