Wow Rich just about got it right come on guys this game at the beginning was great fit the people on this forum, especially me to help to get to know some more of you guys that don't play cod.
If its a messing about session like the mass demolision derby affair or whether missions there's a time and place and you can always go off on your own or split into groups.
The other day I chucked a grenade at Dylan's car as it wouldn't let me in unfortunately he came out of ammunation and he died, for some reason we couldn't hear each other over the mics so as I tried to deliver cars to Simeon Dylan just kept killing me as he thought I'd attacked him for a death match...a bit frustrating but no big deal in fact had to laugh about it.
As for races I just assume anything goes I hate you can use weapons but races are just pure fun, and thanks to Euan he was the reason I didn't come last in every one
So come on guys the best thing about this game is playing in a mass group, just maybe a little more communication is needed?
