Be it World Tour or Ranked Mode, these items always do the trick for me -
ITEM 1: Buy the M-60 gun and get a red dot scope on it. On a serious note, the recoil does feel like it dropped 80% less and this gun shoots smooth with a decent fire rate.
ITEM 2: Buy a dome shield. Always helpful to cash out, if not, it will always work as a barrier to give a bit of pressure to the opponents.
ITEM 3: Buy RPG-7, always good to shoot those low HP's running away from you.
ITEM 4: MOST UNDERRATED AND THE MOST USEFUL ITEM WHICH NO ONE TALKS ABOUT. Buy the pyro mine. I can't even tell you how many kills I have had with these small little mines. For me personally, I get 4-5 kills on the first and second rounds at ease. Place just one mine on top of the dead body or place a mine on your cash out. When the enemy tries to steal it, just shoot the pyro mine which is on the cash out. Second option which is my favorite is to put the mines around the surrounding doors of where the cash out is or just put the mines around the doors if you are running away from an opponent. It's just the brain games at the end, think where the opponent might come from and place a mine right there.
ITEM 5: Specialization used: CHARGE AND SLAM. It helps me with getting away from an opponent or killing them. It's usually for killing them.
ITEM 6: A gorilla outfit. YES, cuz why not? hehe. A giant heavy gorilla with a charge and slam always scares the hell of out of your opponents.

For my spare items, I usually go for a flamethrower gun if I feel like playing short range for the whole game and rest of the equipments are kept the same.

Thank you for reading my guide. This is my first guide and I hope you all benefit from it. I just wanna help at the end, even if it makes a slight difference for anyone.

Cheers.
