When I got the game up and running, my cousin and I played as a team. We are sitting in the same computer room and talk to each other as we play. We are not coordinated enough to play as a team, we just like to play the same game of Team DeathMatch. We got into a server right off and had no trouble with anything (except people killing us but that is normal.) the game ran like a champ and moved us in mid game when it needed to with no lost of anything. Now last Saturday after a steam update the game has problems. We have to join outside of the game as the invite button no longer works. After a half dozen tries, we finally got into a server with both of us intack. However it would throw us out or separate us for no good reason. Between the two Saturdays we went from amazement of how well it worked to "this thing is irritating". Is it just the sheer number of players or did they break the game with the steam update?

I've never been able to invite someone in game. I think me, Slashdawg, and DEFCON tried it and it didn't work.

We were able to do it using the steam icon and choosing friends then join. However it was easier when the invite button worked in CoD-MW2. As I said earlier, this joining does not always work to begin with. Once you play a game, it doesn't lose the friend unless he signs off or uses the bathroom.
