"You got blood on my suit."

(these groups are to see which class is most popular.)

The Spy is the stealth class in Team Fortress 2, using his Cloak and Disguises to blend in and sneak behind enemy lines. A Spy can get behind his foes and silence them in one smooth swipe with the Knife. This used to not be instantaneous when the spy was inches behind his target, but the Scout Update on 24/02/09 made the Backstab almost instant, but also greatly reduced its range. The Spy cannot use weaponry at all while Cloaked, and will lose any active Disguise if a weapon is used except for the Electro Sapper. In addition to being able to eliminate enemies quickly, the Spy is a great anti-Engineer measure. The Spy can place an Electro Sapper on an Engineer's building, disabling it and slowly draining its Health until it is destroyed. However, the Electro Sapper is easily removed by an Engineer with two swings from his Wrench. A common strategy is to Sap a structure and then immediately Backstab the Engineer. A less common tactic is first stabbing the engineer and then quickly sapping the turret before the turret turns around and shoots the spy.
