How do you beat an X1 in Star Wars Battlefront Elite Squadron

People think that you HAVE to be an engineer, but you don't. Here is how I beat him. I was a heavy, and went in. Then, when we started the battle, I took out my lightsaber, and started to attack by holding down B. When he took out his gun, I took out the chaingun, and started firing. When he took out his lightsaber, I did not. I laid down detpacks and set them off when he came near, until I ran out. Then I took the rocket launcher and started firing until I ran out. Then I took out my lightsaber and started to throw it. That's how you win.


P.S.- To dodge the rock , press X while running. Lightning attack in the same, about in the middle of it. Good luck!
