Hunters in halo 3 legendary Tip

On the storm level, after you kill the Scarab, walk up that platform towards the door. When you get up there, turn to your left and there is a couple RoketPods. Bring it with you, just drop it and fight the brutes and pick it and go on. The pod will kill the hunters with 3 shots each.
On the Ark, when you see the hunters. Make sure you clear area of jakels. Save some sniper for the hunters. They will stay behind when everything pulls back so the hunters can work. Stay on that high platform, if you hide up there they will start looking and turn their backs to you. Keep an eye to your right, cause they will try to come around behind you. When you see one start to head that way, when he get to corner of the highwall he has to make a little bunny hop over a step. That gives you a LONG time to make the shot on his back. And if you hit him he'll turn around to go back to his place near his buddy. If he manages to get up there with you, through a the shield down near the edge of the platform, allot of times he will break it and jump back down if he doesn't see you.
On the Covenant, don't fire the laser more than 3 times, to would be better. Take out the first turret with it, I try to let the first brute get between me and the turent for a double kill. From where you popped the first turret, look across to near the back of the antiair-wairth you'll see two brutes side steeping in the open. They'll cross each other every 10or15 seconds, try for a double kill there too. I know there is a laser near the downed pelican but if the chief misses you he always and hits the downed pelican with the fuel rod gun and throwing it who knows where, so don't count on it being there. Save it till you get to the hunters. Two shots to kill the hunters, save the last shot for upstairs for the cheifton(sometimes I can get a triple kill on him). If you hit him alone it "should" kill him if you hit him in the face. But if you hit him and a couple of brutes he'll try to turn on his over shield.
The main tactic i use, is hide when they appear, then they will eventually start looking for you. when one turns around, try to stick his back. when you do this, the big plate will fall off, allowing for any precision weapon (sniper/beam rifle, and BR/carbine) to finish it quickly
