Battlefield 1 is a first-person shooter video game developed by EA DICE and published by Electronic Arts. Despite its name, Battlefield 1 is the fifteenth installment in the Battlefield series, and the first main entry in the series since Battlefield 4. It was released worldwide for Microsoft Windows, PlayStation 4, and Xbox One on October 21, 2016. Similar to its predecessors, Battlefield 1 is a first-person shooter game that emphasizes teamwork. It is set in the period of World War I, and is inspired by historical events. Players can make use of World War I weapons, including bolt-action rifles, automatic and semi-automatic rifles, artillery, flamethrowers, and mustard gas to combat opponents. Melee combat was reworked, with DICE introducing new melee weapons such as sabres, trench clubs, and shovels into the game. These melee weapons were divided into three groups: heavy, medium and light. Players can also take control of various armored vehicles, including light and heavy tanks, armored trucks, cars, torpedo boats, biplane aircraft, an armored train, Reconnaissance vehicles, a Dreadnought and an LZ 30 Airship, as well as ride horses into battle. Destructible environments and weapon customization, features present in the previous games, returned in Battlefield 1 and are more dynamic.
