Also feel free to ask stuff during the game. Most people are friendly enough to help others out. Even the opposing team ;)
Currently I feel the game lacks modes. The current one is either TDM or "who can sneak faster to the enemy base". Somethin with more variety like capture and defense modes. Which are closer to the campaign missions in previous MW games. Or something like a cooperative "horde" mode. Or just a FFA arena. That kind of stuff. The current mode gets too boring after a while.
