1) Practice leading your shot at distances (shooting in front of them in the direction they are headed)
2) THIS IS A BIG ONE... its takes 4 shots to kill someone. what you might not know is The first 3 shots can be anywhere on the body (to take off shields) even in the foot! And the last shot must be in the head to "4 shot" someone. If you shoot at the body, even after the shields are down, it will take 7 shots to kill someone.
Remember the first 3 shots can be anywhere, the last shot must be to the head
2) Go on foundry, have you and your opponent face opposite walls, and on the count of 3 turn around and try to "out br" each other.
3) Every map is a good map, get used to th feel of how you shoot at a specific area of each map with your br, and learn where battle rifle spawns are in each level so you can pick one up and use it more often.
During Battle...
1)When safe always reload, make sure you have atleast half a clip to be ready for another person.
2)Use grenades in the begging of a fight, not in the middle.
3)Get used to the idea of aiming for the head
4)Mele's will make or break you, learn how to use the correctly
If you need any other tips, or if you want me to help you in game (once i get my xbox fixed =\) i can show you what i know =D
Good Luck
