My suggestion would be to get an AR, something that'll take enemies down fast incase you are out of Special/Heavy ammo or you're caught between a rock and a hard place. Second, obtain either a Shotgun or Fusion Rifle that deals Void damage (Of course). Whichever fits your play style. I personally chose a Fusion Rifle called "The Calming" which helped absolutely wreck PvP at a stock upgrade. You'll have to play it safe and wise. No, not by camping, but by knowing the map, not rushing in to try and murder everyone, and by keeping a slight distance. Get a Void Heavy, I chose a Rocket Launcher. Finally play in Control, capture B, get a good feeling of where your enemy is, or where he/she will come from. All I can think of saying... Oh, yes! Do not let the 500 points or deaths get to you, keep a positive attitude and don't rage. I did it in roughly 2 hours but I was also a Voidwalker. I wish you the best of luck.
