This article is about the stock building item for the Spy. For other sappers, see Sapper (disambiguation).

The Sapper, mentioned in the Sentry Gun Operational Guide as the FM/AM Sapper, is the default Building weapon for the Spy. It is a small box inscribed 'ELECTRO-SAPPER' and sports a dial and switches. It also features two clamps that are deployed when used.

The sole function of the Sapper is to destroy an Engineer's buildings. Should the player select the weapon and stand near an enemy structure, they will be able to see a white outline of the Sapper on the building, indicating that it is in range and can be sapped. Additionally, the needle on the gauge will move to the right red zone. Pressing the primary fire key, default MOUSE1, will attach the weapon, and the building will slowly be damaged until it is destroyed. A sapped building will cease to function; Sentry Guns will not fire, Dispensers will not heal or dispense ammo and Teleporters will not teleport. When applied to buildings, the Sapper will produce electrical sparks and a loud hissing noise. When a Sapper is attached to one end of a Teleporter, another Sapper is automatically placed on the other end of the Teleporter, if it exists. If the Spy is disguised, the disguise class will play a distinct, unique animation of placing the device on the building. Unlike the Spy's other weapons, using a Sapper will not cause him to lose his disguise.

For each building the Spy player places a Sapper upon, a small window in their HUD will appear showing both the remaining health of the building sapped and the health of the Sapper on that building.

Once the building is being sapped, the Engineer owner will be alerted to it in his HUD, and will automatically play a voice clip alerting nearby players of the building's predicament. Engineers can remove a Sapper with two hits from their melee weapon. When a Sapper is attacked, the Spy player will be notified by a similar alert in their HUD. If an Engineer removes a Sapper from a Teleporter, the Sapper at the other end is also removed. If another Engineer strikes the Sapper first, he can get an assist for the Sapper kill, and a Medic healing an Engineer can also score an assist in this way. Pyros equipped with the Homewrecker, Maul or Neon Annihilator can also destroy Sappers if they happen to come upon them. Enemies focused on removing Sappers may leave themselves open to a backstab or headshot, allowing the Spy or a teammate to distract and dispose of enemies in addition to the building in question.

The Sapper has infinite ammunition and no discernible "cooldown" time; Sappers can be placed on a building faster than an Engineer can repair the damage each one causes, which guarantees the building will be destroyed if the Spy is not dealt with. This tactic seldom works if there are multiple players around.

The Sapper breaks into metal fragments upon removal. The fragments can only be picked up for metal after being destroyed on a Dispenser, each gib giving 3 metal.

Sapped Sentry Guns only take half of the damage from the Spy who applied the Sapper, for example when shooting it with a Revolver. Dispensers and Teleporters are unaffected by this.

In Mann vs Machine mode, attaching a Sapper to a robot will disable it and any other robots within a defined radius. However, unlike regular multiplayer, there is a cooldown time enforced before a new Sapper can be deployed.

Unused content

  • The game files have referenced a taunt for the Sapper since the game's launch, however, the animation is not present in the Spy's animation set.

Bugs

  • An issue can occur when the Sapper is placed on a building that upgrades to the next level at the same time; the Sapper will be unremovable by both Engineers or Pyros equipped with the Homewrecker or Maul. Additionally, the sapped building will function as normal, albeit with draining health. Hauling the affected building corrects the problem.
  • The idle animation does not play during a replay, causing the needle to remain still.
  • Occasionally, a Sapper war between a Engineer and a Spy on two ends of a teleporter will result in the Sapper being removed from the Engineer's end and not from the Spy's end.

Trivia

  • Sappers are considered by the game to be buildings. As such, they are immune to critical hits (they are not destroyed in one hit by a single critical Wrench swing) and can be created with the build console command.
  • A Template:W is a combat engineer who typically builds or demolishes structures in warfare.
