Team DeathMatch Multiplayer

[vulcan]

Hey,

I am looking for a good down to earth mission plan for a team death match mission against two large clans. I need more then just put all the west stuff on the west side and east stuff on the east. Maybe like CTi or nogovo campaign were you have to take towns and place AI to defend them. I just need some good ideas for a "Big War" MP game that will last a very long time. up to 3 hrs ?

thanks for your input
