The Frontier consisted mostly of wilderness inhabited by a variety of animals. Hunting Regions split up the land, where hunters could track and kill different types of game.
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 settlements. These included the towns of Lexington, Concord, Charlestown, and the Kanien'kehá:ka village, Kanatahséton. Small logging, fishing, and mining posts could also be located.
As the Revolutionary War waged on, the condition of the towns would change as a consequence of the battles. At different times, battalions of men could be found readying for a charge, or injured soldiers could be spotted.
