Hey, I'm new, and i don't have found an article about, how I play this game online. In the multiplayer mode i've found some servers. But i can't play against my friend. What should i do, and is it able to play so?

Look at the number of the server, name of the server. If that would not work look at the IP adress and tell it to your friend.That is how.

Hmm, you have to go to "Setup" on the menu, and then login with your user name and password. Then Press escape, then click "Multi player" then pick a serve rthat your friend is in and fight.

Oh, but I though... thanks alot Aaron, I forget that :|
