The Spy, unlike any other class in the game, heavily relies on stealth. Using a unique array of cloaking watches, he can render himself completely invisible or even fake his own death, leaving unaware opponents off-guard. His Disguise Kit lets him take on the form of any class on either team, allowing him to blend in while behind enemy lines before stabbing his unsuspecting "teammates" in the back. In fact, a swift backstab with any of the Spy's knives will always kill an opponent in one hit.
