As in
Battlefield 1942, players play the role of a soldier in a two-sided battle and can choose which weapons and/or vehicles they want to use in accomplishing this task of victory on the battlefield. Usually, the team that works together more effectively wins by reducing the enemies' tickets to zero in a classic "Conquest" mode. (A team loses tickets when its members are killed, but also when the other team holds a majority of the capture points on a map.) Even more so than in
Battlefield 1942, the weapons in
Secret Weapons of WWII are designed to be used in unison with other weapons to compensate for weaknesses and maximize strengths. The default Allied (US) Army and
Axis (German) Army have received new weapons and vehicles in addition to the creation of two entirely new factions, the
SAS (
British Commandos) and the German Elite Troops (the
Waffen-SS and the
Fallschirmjager). The accompanying update package 1.41 introduces an additional three new factions,
USMC,
RAF, and
Luftwaffe. Each faction has unique weapons to their faction that can only be obtained by playing as that faction or picking them off a fallen enemy soldier. They also have unique vehicles that are only available at their bases. Even with the creation of these new factions, all the maps in the expansion pack are Axis versus Allies, as is the custom in the
Battlefield series. Also of special note is the
Jet Pack, which allows players to fly in the air while firing a weapon. To maintain gameplay balance, the Jet Pack is very susceptible to blowing up while under fire, instantly killing the player. As opposed to other weapons, the Jet Pack is not unique to one faction, and instead, it can be found at one or more locations throughout a particular map as an item that replaces the player's current equipment. ==Development==
