There is no voice in bf3 except through Origin and you have join the party to be involved. The only swearing per say will be typed out in chat and there are filters for that. GC rules would and will be enforced to a certain degree. 1 warning, kick then if persistent banned. The difference between this game and L4D is that you can go up in the mountains and camp sniping till your heart is content. It won't kill the team. It will be like CS but a different (and better lol) game. No worries. Clueless and I have been to this rodeo before. Scopeless.
I have confidence that we can make it work.
