Battlefield:1943 is a great demo for many particular reasons. You are a soldier of WWII fighting for the glory of the army for which you fight for! You may become an Imperial Japanese soldier, or a battle-hardened U.S. Marine. In the demo, you get to choose between three classes of soldiers and you are able to man guns, fly planes, drive jeeps, or even take a spin in a destructive tank! The demo is for online purposes only and it is free. However, the demo itself is timed and will expire after you have used it.
