This video shows you how to play with more than 4 friends in Bad Company 2 and how to get them on the same team. There are a few different ways of doing it. Also is a tutorial on the UAV C4 Trick that is being used online in Rush mode. I do not like the trick and I hope they fix it - But knowledge is power and I feel you should be aware of everything in the game. Counter this attack by making sure you target UAVs and their drivers.
