This is a gamemode idea I have came up with although, I am not sure how well balanced it would be. It would be called something like president as that is the name of the paintball game I got the idea from.
There would be two teams, one which includes the president and his two body guards and the attackers. The president would be driving a cheap possibly free car, and his bodyguards would have tier 3 vehicles. The attackers would have tier 1 vehicles. The aim for the attackers is to knock down the president and the bodyguards have to try and keep the president alive by intercepting the attackers. The president would have to survive for a certain amount of time to win.
The president and the bodyguards would have only one life but the attackers could respawn.
