In this game, the hunter weapons shoot a continual blast of plasma for a couple of seconds. To didge them, keep walking to the side and you will not be hit(at least you won't have to worry about getting hurt for standing near the shot like in Halo "1"). Shooting them in their front sides won't work unless they have their arm sheilds down, which doesn't happen once they shoot you. If you are in an inclosed space or small area, get close to them and wait for them to smack you. Before they make contact, sidestep, get behind them, and shoot them in their backs. This usually takes a couple of tries per Hunter. Frags don't do much damage, so they are useless, and plasma 'nades won't do much unless you just want ot piss them off, plus they will track you and you will get hurt by the plasma blast. When you are in a lare area, shoot them in the backs with a sniper or laser beam rifle, that will usually kill them instantly.
