Like Battlefield: Bad Company, 1943 features the Frostbite Engine for its environmental damage. The game only features the series' signature Conquest mode and a new game type called Air Superiority which was unlocked when the online gaming community reached a combined total of 43 million kills in Conquest. Similar to Battlefield Heroes, 1943 features only three classes: Infantryman, armed with an SMG and anti-tank rocket; Rifleman, armed with a semi-automatic rifle and rifle grenade; and Scout, armed with a scoped rifle, pistol, and dynamite. Each class has an unlimited supply of ammunition. Explosive ordnance, however, does take time to replenish. The game also features a regenerating health system. There are four types of vehicles in the game; fighter, tank, car and landing craft. Each team's main base has two one-man fighter aircraft, with A6M2 Zeros for the Imperial Navy and F4U Corsairs for the United States Marine Corps. On every map there is also an airfield for either team to capture where a third plane can be used to a team's advantage. Each airplane has four machine guns and can also drop bombs. Tanks can accommodate two players, a driver who can use a tank cannon and a coaxial machine gun, and a passenger who can use a mounted machine gun. Cars can accommodate up to three players: a driver, a gunner in the back who operates a machine gun, and a passenger who can fire their own weapon. Landing craft (boats) are used to deliver troops from the carriers to the beaches. Players can also use air raid bunkers to attack with three bomber aircraft to clear an area of a map. To operate these, the player must enter a bunker with a large spinning dish on top. Planes can be shot down by fighter pilots and anti-aircraft guns, reducing the amount of bombs that the air raid can deliver, or destroying it entirely.
