I could show you some good camping spots, but none that will get you so many kills it really depends on your own type of gameplay do you like camping or rushing?





Sub or Assault?





Jugg or Sleight of hand.





Personally heres my FAVOURITE class if it helps ;)





M4 Carbine


Bandolier


Sleight of Hand


Steady Aim





Red Dot ;)
