Assassin's Creed 3:

The main portion of Assassin's Creed III is set before, during and after the American Revolution from 1753 to 1783 featuring a new half English and half Mohawk protagonist; Ratonhnhaké:ton, also known by the adopted name of "Connor". In addition to the historical period, the game also features the "present day" setting, where series protagonist Desmond Miles must adventure to prevent the 2012 apocalypse, as his story develops and reaches a conclusion.

New gameplay additions include muskets and rifles, which can be fired at a considerable reload time, or used as a melee weapon. Hiding places can now be mobile, such as haystacks in wagons or moving carts, which can be used to sneak up closer to targets. Disguises can also be worn, fooling normal troops and only risking investigation by officers.
Free running has been modified to allow for more fluid, parkour-like movement over certain obstacles. Exploration has also been modified, allowing for map areas to be revealed without requiring a viewpoint synchronization.
Close combat has been modified, slowing during blocks to allow for more options in attack and defense. Human shields can be taken against firing lines of enemies.

Assassin's Creed III features new weather simulations such as snow, fog, and rain. Depending on the seasons, weather determines how enemies/players will move around. Heavy snowfall makes it more difficult to travel.
Players are now able to trap and hunt animals for skins in the wilderness. Hostile animals, such as Bears and Wolves also exist, and will attack the player on sight. The value of an animal's hide is determined by the method of killing. Muskets, flintlock pistols, and multiple attacks will make pelts less valuable while a single stab or shot with a bow will increase the value.

Another major addition is the Davenport Homestead missions. Starting with a single house and a few outbuildings, the player can perform missions for NPCs in order to convince them to settle near the Homestead, providing the player with raw materials and crafting facilities. Recipes for crafting can be obtained. Raw goods and crafts can then be used as part of a local economy, selling them at market by either land caravan or via sea convoys. Dependent on the goods being traded and the level of threat nearby, these goods can be attacked and stolen, or sold for a profit.
Assassin's Creed III also features naval expeditions
