A multiplayer mob game in the style of call of duty sounds awesome...but it would be difficult to implement.
You can't really do a sit down or a mob style hit in a multiplayer game.
It really just sounds like a giant clusterfuck when I think about how you would try to do these kind of things.
Just think of governments as competitive organized crime syndicates trying to whack each other during those army games I guess.
Long as I remember The rain been coming down. Clouds of Mystery pouring Confusion on the ground. Good men through the ages, Trying to find the sun; And I wonder, Still I wonder, Who'll stop the rain.
