Ok what ya do is this. Go to
www.zone.com and log in. (If you havn't already got a screenname then you'll have to get a .net passport so basically go and set up a hotmail account.) Once you've loggd into the zone click on the Combat Flight Simulator 2 jimmy and wait for all pictures to start loading then go to midway. A wierd zone thing will come along and then all you need to do is choose a game and press join. I would suggest getting DirectX8.1 before you start and make sure theres a file called multiplayer.mis in your main CFS2 Directory (That was the file that caused me so much grief!) It should still be there but theres no harm in checking. Erm yeah so there you go.....
P.s. I can now take out Ace Zeros with a Hurricane so watch out!!!!
