While playing as the Sneaker, equip your cloaking ability in a multi-player match. While holding your saber, jump down from a high area (for example, the beginning of the Beach Dead map). About half a second before you hit the ground, press X to activate your cloaking ability. If done correctly, your character should hit the ground fully cloaked, and you will not have to wait to activate it on the arm panel and flash. This is particularly useful for jumping into battlefields to surprise the enemy.
