Battlefield 1942 is the reference of FPS multiplayer simply because it looks great graphically, on the internet this game can play a maximum of 32 players that will allow you to make great battles of WW2 time a soldier or driving a tank, a plane, a jeep while over 43 vehicles! But that's not all! Many changes exist for this game including the most famous and best: Desert Combat that immerses you in the Iraq war, with an impressive realism, weapons, tanks, soldiers, aircraft everything has changed! A connection 512 will suffice because the lag (deceleration) is very rare. By cons, those without adsl must go their way. Here is a superb network game that I highly recommend!
