if its SMG'S your needing to just go on chaos moshpit and it will come eventually

Try hardcore, I need the Razorback gold for diamond, but I have postponed it because I hate it, today I unlocked gold for the Man of War, XR-2 and the KN-44, I managed to get the headshots and longshots done quite easily, there is really no easy way to earn this than boosting it is just time consuming. Just remember to use high calibre for headshots and Varix scope for longshots.

yeah same here. im working on razerback right now then they are diamond. just got 75 headshots. should have it gold by today

I just prestiged yesterday, only a few levels away from it again, hopefully getting diamond to tomorrow, just working on the M8 atm.

Im going for dark matter and all I have left are ARs. The main tip I have is to play hardcore FFA. Hardcore makes it a lot easier to get head shots, and I feel that FFA is the easiest and quickest game mode for the head shots.

One tip I have for the bloodthirstys are using the rejack ability. It makes it much easier to get the challenge done since you can die and it won't end your streak for the challenge. The bloodthirsty medal won't pop up in game but it will count towards your challenge.

Good luck!

The best way to get Dark Matter is to play Bonus > Chaos Moshpit and only stay in games where Nuketown is the map. Always have High Caliber and a Grip on your gun if you're going for gold and it is available. For shotguns and pistols, use laser sight (it helps a lot).

For the longshots, use the varix scope if available on that gun and be sure to be zoomed OUT while using it. (Makes it so that you can get longshots at much shorter distances) and also use the suppressor because it has the same affect.

Best of luck!
I'm 3rd Prestige right now and have about half of my guns gold.
