You have to be patient. There are newbies, just need to wait for them to join your game or find one.
Also, not all of us are dickheads who kick out new players. I'll play with ye.
What you can do is play single player to learn the chars. Or better, Download the mods (look in this forum), start a multiplayer and play against AI. It will not count towards your record if you win or loose. You can test alot of things and get better.
Once people. like myself, see that you have a basic understanding for the game, and you can control your char, then its no big problem to join most games. There still will be some twats that will kick you untill you have a good % or alot of games. Just need patience....
Play Multiplayer yourself. Learn, then you shouldnt have much problems.
