Void rocket launchers are also good for getting several kills at control points. You can judge the number of enemies at a control zone by how quickly the capture meter is filling then blast Truth into their faces for quick points. I wouldn't count on heavy ammo, though. Back when I did it, shotguns were the best way. That was before the first nerf, though. Today, I think I'd go with a fusion rifle or Atheon's Epilogue, obviously.
