I get the feeling that many of you have no idea as to what I am talking about so I offer a short explaination.
Bombing run is like CTF in the sense that both teams have a area that they should try to control, a red side and a blue side. There is a ball in the middle, and the object of the game is to shoot the ball thru the other teams goal. When someone has the ball they are without attack abilities. To get the ball they must either shoot it and miss or they must be killed. If the ball falls off a ledge it is reset in the middle. When a goal is scored all teams respawn at their bases and the ball is back in the middle.
Its great fun.
