Assassin's Creed III
The following weapons appear in the video game Assassin's Creed III:
A Braddock Pistol is available for use. According to the description it was made by a Spanish gunsmith named Gabbitas and has the initials "E.B." on it.
Double Barrel Pistol
A Double Barrel Pistol of British origin can be used by Connor. It can fire two shots allowing for quicker takedowns on enemies.
"Duck Foot" Flintlock Pistol
The "Duck Foot" Flintlock Pistol is a sidearm available in the game. Though real Duck Foot pistols usually had four barrels, there were also three barreled variants. According to the in game description it is popular with jail keepers (despite the ones at Bridewell Prison in New York never using them) and naval officers to discourage mutiny. Another version is available called the "Naval Duckfoot".
French Coat Pistol
A pistol by the name of "French Coat" can be used. It can shoot two times due to a double trigger.
Harper's Ferry Flintlock
The Harper's Ferry Flintlock is the game's default pistol and is used by Connor, Haytham Kenway, British Officers, Sergeants, Charles Lee, Connor's ship crew, Templar agents, and the "Jäger". Connor has the option of carrying two of these by crafting a pistol sheath with two holsters. The Harper's Ferry Flintlock is anachronistic as the first model was not made until 1805.
Heckler & Koch Mark 23 Phase II Prototype
Daniel Cross's weapon of choice is a Heckler & Koch Mark 23 Phase II Prototype when Desmond retrieves a power cell in Manhattan. Later Cross also uses a suppressed Mark 23 in Brazil and Italy. The Mark 23 is also used by Abstergo guards and Desmond.
An Italian Flintlock can be bought and used by Connor. The description states that the ramrod is made of walnut.
Two Pitcairn-Putnam Pistols can be bought. The description says that these pistols are copies of the ones given to Major General Israel Putnam in Lexington and has the coat of arms for the Crosbie family.
The Royal Navy Sea Service Flintlock can be bought and used.
The Royal Pistol is available to Connor.
The "Scottish Flintlock" is actually based more on an 18th century Russian flintlock.
Cannons are a common sight in the game seen in use by the British Army, the Continental Army, and the Crew of Connor's ship the Aquila. The cannons on the Aquila are operated by one crew member while the ones used by the Armies have 2-3 man crews. They can also fire Grapeshot and Chain-shot.
The Aquila has several Swivel Guns mounted on it.
Naval mines are encountered in the seas to deter British Ships.
Smoke Bombs are available for use. They work as expected to as in to provide a chance to get away.
Trip Mines are pressure detonated explosives to be used to ambush convoys.
Enfield Pattern 1853
An Enfield Pattern 1853 incorrectly shown with flintlock lockwork appears as the standard long gun of the British Army, the Continental Army, couriers, Templar agents, tax collectors, poachers, thieves, Bridewell Prison guards, Connor's ship crew, and Connor's Indian tribe. It is extremely anachronistic since it would not be invented for almost a century, and is probably supposed to be a Brown Bess Flintlock Musket.
