Hello Im playing on headlong with the banshee in multyplayer my friend..

Why do you take the Banshee if you know he is going to kill you. If you press A and left thumbstick sideways you will do a Banshee- trick and that should fool it enough for you to get time to shoot your friend or fly down and jump out of the Banshee. If your very skilled you do it close to a building and the rocket should hit the buildin instead of you.

Is he on the other team? If he is, the rocket will follow you. If he's on your side, it won't flollow you.

Just an idea here, if you know he has a rocket launcher don't take any vehicles(although you can sometimes evade rockets in a banshee if you do banshee tricks at the right time by pressing A and moving the left thumbstick to the left, right or up at the same time) instead try to stay far away from your friend and and kill him from a long way off with a beam rifle, sniper rifle, battle rifle or a carbine. Or you could always get the rocket launcher first and blow your friend away.

Hope this helps.

While in a vehicle and another person has the rocket launcher it locks on and follows you

Ok, it's pretty simple, all you have to do is do a banshee trick (ex. A left, A right, A up) right before the missle hits you, or you can try out running it but it is kinda hard to do.

Make your banshee do tricks to avoid the rocket. Hold down A and then use the control stick.
