The game is a first-person shooter like the rest of the Call of Duty games. Its focus is on its single-player campaigns, as it has no multiplayer. The game is set in World War II. The player can carry two guns at one time, and can carry grenades. Levels are played with a team of soldiers from both Britain and the U.S., while helping him or her by killing enemies and opening doors. The game has been criticised by some critics for the poor AI, displayed when friendly soldiers push you out of cover and into the enemy line-of-fire.
The Game has 4 campaigns: War in the Pacific, Winter Offensive, Victory in Europe, and Victory in the Pacific. The player takes on the role of a marine in the Pacific campaigns and both British and American soldiers in the European campaign. Unlike other "World at War" titles, Final Fronts has a training level. The War in the Pacific and Victory in the Pacific Campaigns see Private Joe Miller (a reference to World at War protagonist C. Miller) and his fellow soldiers Sgt. Roebuck and Pvt. Polonsky (also in World at War) fight their way through Japanese defenses on Guadalcanal, Betio, Saipan, and Okinawa. A major difference in the American campaign from World at War is the fact that both Roebuck and Polonsky survive the final battle for Okinawa (also, Sgt. Roebuck shares a similar character model to Sgt. Dixon from Call of Duty 3). The Winter Offensive and Victory in the Europe campaigns have three protagonists: Pvt. Lucas Gibson of the US 80th Infantry Division of George S. Patton's Third Army, Pvt. Tom Sharpe of the British 6th Airborne Division, and Gunnery Sergeant Alex McCall of the US 4th Armored Division. The Winter Offensive campaign sees the Americans and British move to relieve the city of Bastogne (while the 80th take Ettelbruck in Luxembourg), and the Victory in Europe campaign sees the British 6th Airborne Division capture the town of Weser during Operation Varsity and the Americans capture Adolf Hitler's birthplace of Braunau-am-Inn in Austria.
The PlayStation 2 game was not developed by Treyarch, the studio that made the other versions. Rather, its development was outsourced to British studio Rebellion. Built using the Asura engine as opposed to the id Tech engine used for the other versions, Final Fronts allows players to employ elements like fire to affect the dynamics of the battlefield. Some voice tracks are recycled from previous games, predominantly the German voice tracks. As stated before, Sergeant Roebuck shares a character model with Mike Dixon from Call of Duty 3, although he is voiced by Kiefer Sutherland, who voices him in World at War as well.
