Halo 3 - Construct
Swords: If you find your way into a swords match, or simply are wielding a sword while an opponent wields one as well, be aware that using the melee attack with the sword is faster than using the weapons main attack. The melee does not produce the lunge, but, if landed, will cause a one hit kill. Following up with a much faster melee attack after a sword clash will commonly give you the win.
