Hello mates. I bought Call of Duty 4 this morning and i don't know what i'm supposed to do to play online(Multiplayer). I've never played a game online, so i have no idea. Do i have to register somewhere?? I run multiplayer mode but it doesn't find any Server.
Thanks!

maybe you need the latest patch. i think its 1.4 or something.

Usually you have to input the server you want to connect to, or there may be a setting to automatically search for a server matching your criteria.

You might want to look at GameSpy. It not only has patches and mods, but I believe it also has "hosting" for many games.

u need the patch
