New WWII-era weapons like the MP 40, the M3 submachine gun, the MG 42 and the Beretta Model 38 also appear in the game. Many firearms from the previous return, such as the Thompson submachine gun and Colt 1911, as well as a pump-action shotgun (though it was changed from a Winchester Model 12 to a Remington 870). There are 30-40 vehicles in the game (45 with DLC) as well as licensed music from the era.
The game is set in the 1940-50s era of Empire Bay, a fictional city based on New York City, Chicago, Los Angeles, San Francisco, Boston and Detroit.
