Some ideas

Vehicles:
If there was a button which allowed you to change which direction tou were firing, like to the left and right of the vehicle, and for grenades you could throw them behind yourself.

Also an option where you could turn off character detection in the map, and also an option where tou can just turn off the map in general, so that way players can prepare ambushes, and there is some fear in not knowing where your opponents are.

Tanks are too op, they need a lot more firing lag instead of being able to fire rockets like bullets from a minigun. :)

Being able to turn off pistol so that the only weapon allowed is the knife would be cool too, as well as a mode where no weapons and or vehicles spawn, the only stuff you have is stuff you started with.
