The following technique is most useful in Energy Sword games or whenever two opponents with Energy Swords are battling. However, it can be utilized in any situation when you are up against someone wielding the sword.

Underwear

When approaching someone who has the Energy Sword, wait until right before you think they will lunge at you - and then duck. Very often the attacking player will lunge right over top of you. If you are swordless, this will give you a chance to turn around and finish your shooting. If you also have an Energy Sword, remain ducked as the person lunges at you and then press the right trigger button and lunge at the opponent. This should increase your success.

Bonus Tip!

To defend against or counter the above technique, simply aim low with your Energy Sword crosshair when you see the opposing player ducking or duck yourself. This will give your melee attack a low center of gravity.
