Thanks goes to MadGuy from our forum's who noticed that the Demo had been released on EA's Battlefield:1942 website.
Get ready for a World War II experience like you've never imagined. Weapons and vehicles from the Allied and Axis laboratories are about to see combat for the first time in the stand alone multiplayer demo for Battlefield 1942: Secret Weapons of WWII, the incredible new expansion pack for the 2002 Game of the Year.
The demo also unleashes the power of ten of the 16 new weapons in Secret Weapons of WWII. Fly and fight at the same time with the experimental German rocket pack, or buzz the skies in one of the new compact dynamo fighter planes—the Axis Natter rocket plane or the Allied F-85 Goblin. Both the Axis and Allies also have new motorcycles with machine gun-mounted sidecars, as well as amphibious assault vehicles: the German Schwimmwagen and the American LVT-2 Water Buffalo. The new Axis Flakpanzer, a T-38 tank with an anti-aircraft gun mounted on top, is a nasty beast—but it looks tame compared to the Allies' Sherman tank with a T-34 Calliope rocket launcher.
With all this plus new hand-held weapons such as silenced SMGs, new assault rifles, and deadly throwing knives, become a deadly force on the most intense virtual battlefields ever created.
