i couldnt find any path. and im not friends with them im just trying to join their matches. their friends list is full but they host some matches once in a while
What do you mean by "their friends list is full"? The steam friends list can be (basically) infinitly long. To join you need their direct IP address. I don't really think this will work very safely, since most people get a new IP every 24h hours. Usually the port is 28960 (at least it was in MW2 and I managed to connect to people with that in alterIW).
So, what you need to do is - go to the steam library - go to MW3 MP - properties - set start parameters or something and add "+connect 127.0.0.1:28960" IF IW hasn't blocked out the connect command. Otherwise you could also add a 'bind F1 "connect 127.0.0.1:28960" ' in the config_mp.cfg, again, if the command still works. Still, this is a very unreliable method, just get them to be you friends with on steam.
Oh yeah, 127.0.0.1 needs to be replaced with whatever IP you want to join - 127.0.0.1 is always your own computer.
