The Frontier consisted mostly of wilderness, containing cliffs, forests, rivers, and mountains. It was also inhabited by a variety of animals, including bears, beavers, deer, wolves, rabbits, and elk.
While Boston and New York City were the primary settlements located near the Frontier, the countryside itself also contained several small Native American and European ones, including the towns of Lexington, Concord, Charlestown, and Connor Kenway's Mohawk village. One could also find logging camps, mills, and trading posts.
As the war dragged on, the condition of the towns would change during the preparation or aftermath of a battle. At different times, one could find battalions of men readying for a charge, or injured soldiers by abandoned tents.
- The Frontier is reputedly 1.5 times larger than Assassin's Creed: Brotherhood's Rome, meaning it will be the largest map in the Assassin's Creed series.
- The Frontier is the setting for around 30% of the main storyline content for Assassin's Creed III.
