I will tell you exactly what would happen…
_*Master Chief walking through snowy warzone*
Darth Vader: Ahh, at last, we meet. Now, prepare to die. Draws lightsaber
Master Chief: Ha, I’ll kick your ass.
Darth Vader shoves lightsaber through Master Chief and walks away
Master Chief on ground grabs pistol and shoots in back
Vader: Ahahahahaa…. That will not help you… Die!
