Instead of buying the first five DLC's one by one, grabbing this pass lets you save 25%, and you get to play the content a week before anybody else.
Also, details on the first DLC planned for the game was also announced.
The first DLC that will be included in this Season Pass is called "The Tyranny of King George". It's a whole new single player campaign that's divided into three episodes releasing one by one. It's an altered history, with George Washington as a Tyrant king, and Conner tasked to dethrone Washington and bring back freedom to the land.
The Season Pass will also include multiplayer map and characters as DLC in the future. The pass will be available for Playstation 3, Xbox 360, and PC.
Assassin's Creed 3 hits stores on October 30 on Playstation 3, and Xbox 360. The PC version will be released a bit later on November 20. The Wii U version will be available on November 18, the console's launch day.
