Halo 3 shotgun tip

One of my best things to do on matchmaking is 1. Use the shotgun at any given moment that you have and atempt to always melee directly after you shoot to make sure that they are dead shield sometimes wil just go down and they wont go down 2. If the other person has a shotgun, then keep distance between you and the shotgunner, and shoot them a lot. Playing with friends on your team will also help you have better communication.Try and make head shots for a quick kill.
