Once deployed, the Sentry Buster makes a beeline for the Sentry Gun that triggered its appearance while making a beeping noise if you get close. Additionally, a voice response from the [[Administrator]], the [[Engineer]] who built the targeted Sentry Gun, and, in some cases, from friendly [[Heavy|Heavies]], [[Soldier]]s, and [[Medic]]s is played to alert the team of the sentry buster's appearance. Upon reaching its target, it crouches and begins [[Media:Mvm sentrybuster spin.wav|beeping]]. About 3 seconds later, it detonates in a massive explosion guaranteed to level the offending Sentry and just about anything else within approximately a three-[[Teleporters|Teleporter]] radius, including other non-giant robots around it. If giant robots are in the Sentry Buster's explosion as it detonates, the giant only takes 600 damage. If another Sentry Buster is caught in the explosion it also begins its own detonation, even if it is still in spawn or [[ÜberCharge]]d by a Medic bot.

Sentry Busters can simply be killed before they reach their target, which causes them to wind up and explode prematurely. [[Haul]]ing the Sentry after Sentry Busters get close to the Engineer's sentry is recommended, as Sentry Busters cannot move once they begin counting down, but that does not protect any other buildings or teammates that may be nearby. An Engineer picking up his Sentry and carrying it around the map is not recommended, as it stops the Engineer and his Sentry from attacking the rest of the horde and attending to his other buildings. [[Knockback]] can keep a Sentry Buster at bay long enough to destroy it, but once they begin the detonation process, they are immune to it (excluding [[compression blast]]). However, regardless of how a team defeats a Sentry Buster, the robot horde continues to send them out after a mission-specific delay time until the target Sentry is destroyed or the wave is completed. The [[Rescue Ranger]] allows an Engineer to pick up his Sentry Gun from a distance, assuming that he has at least 100 Metal. This allows him to safely wait until the Sentry Buster starts detonating, then quickly withdraw his Sentry Gun before it explodes. | |

” |
The Sentry Buster is a specialized robot that appears in Mann vs. Machine when a Sentry Gun has dealt significant damage to the robot horde. It appears as a large pair of legs similar to a Demoman Robot, but with a large naval mine for a torso.
Once a defending Sentry Gun has reached a certain amount of kills or damage (see Spawning requirements), a Sentry Buster is dispatched; they do not appear under any other circumstances. Once deployed, the Sentry Buster makes a beeline for the Sentry Gun that triggered its appearance while making a beeping noise if you get close. Additionally, a voice response from the Administrator, the Engineer who built the targeted Sentry Gun, and, in some cases, from friendly Heavies, Soldiers, and Medics is played to alert the team of the sentry buster's appearance. Upon reaching its target, it crouches and begins beeping. About 3 seconds later, it detonates in a massive explosion guaranteed to level the offending Sentry and just about anything else within approximately a three-Teleporter radius, including other non-giant robots around it. If giant robots are in the Sentry Buster's explosion as it detonates, the giant only takes 600 damage. If another Sentry Buster is caught in the explosion it also begins its own detonation, even if it is still in spawn or ÜberCharged by a Medic bot. The splash of the explosion will pass through the Medic's Projectile Shield, if you are still in range.
While inattentive Engineers are sure to lose at least their Sentry to a Sentry Buster, aware ones with a competent team can deal with it without too much trouble. Sentry Busters can simply be killed before they reach their target, which causes them to wind up and explode prematurely. Hauling the Sentry after Sentry Busters get close to the Engineer's sentry is recommended, as Sentry Busters cannot move once they begin counting down, but that does not protect any other buildings or teammates that may be nearby. An Engineer picking up his Sentry and carrying it around the map is not recommended, as it stops the Engineer and his Sentry from attacking the rest of the horde and attending to his other buildings. Knockback can keep a Sentry Buster at bay long enough to destroy it, but once they begin the detonation process, they are immune to it (excluding compression blast). However, regardless of how a team defeats a Sentry Buster, the robot horde continues to send them out after a mission-specific delay time until the target Sentry is destroyed or the wave is completed. The Rescue Ranger allows an Engineer to pick up his Sentry Gun from a distance, assuming that he has at least 100 Metal. This allows him to safely wait until the Sentry Buster starts detonating, then quickly withdraw his Sentry Gun before it explodes.
Sentry Busters spawn against and target Mini-Sentry Guns, but they ignore Disposable Sentry Guns, even if it is doing more work than the primary one. If a Sentry is destroyed before the Sentry Buster gets there, it continues running to where the Sentry used to be and then detonates. If a Sentry dies high enough in the air (in the case of an Engineer dying midair while hauling one) before the Sentry Buster can reach the Sentry Gun, it runs around the area directly below, often giving up and detonating after a few seconds. Rarely, they may become stuck and not detonate for a few minutes, or if the team sufficiently damages it. These Sentry Busters do not prevent new Busters from spawning, and a new one spawns after the cool-down period, as long as the Engineer rebuilds the Sentry and it is not destroyed by other robots. A Sentry Buster self detonates if it cannot find a path to a Sentry Gun.
Destroyed Sentry Busters, whether by themselves or by the players, leave no credits. A large cloud of dark grey smoke lasting a few seconds remains after detonation, blocking the view of players within the range of the smoke.

Spawning requirements
The Sentry Buster only spawns when a Sentry Gun reaches a specific kill or damage threshold. This threshold is dynamic depending on the amount of non-disposable Sentry Guns on the map, decreasing with every additional Sentry Gun, up to a maximum of six Sentry Guns. These values are the same for every Valve-made mission, however, custom missions can set custom thresholds with the attributes AddSentryBusterWhenDamageDealtExceeds and AddSentryBusterWhenKillCountExceeds. Each Sentry must hit one of the thresholds for a Sentry Buster to spawn for that Sentry Gun. Sentry Busters spawn in waves depending on their cool-down times, which is mission-specific (in some cases, such as Bavarian Botbash, the cool-down times are also wave-specific). The first wave of Sentry Busters also has a per-mission (in some cases, per-wave) delay, and cannot spawn until a certain amount of seconds has passed since the wave began. Only one Sentry Buster spawns per Sentry per spawn wave. Kills and damage dealt is only reset when a Sentry is destroyed by the robots, or if the wave ends. If an Engineer destroys their Sentry one kill before a Sentry Buster would have spawned, then one spawns when their next Sentry gets a single kill, provided the robots do not destroy it while it is building.
| Sentry Guns | Kills | Damage |
|---|---|---|
| 1 | 15 | 3000 |
| 2 | 13 | 2700 |
| 3 | 12 | 2400 |
| 4 | 10 | 2100 |
| 5 | 9 | 1800 |
| 6+ | 7 | 1500 |
Note: Giant kills count as 5 kills in regards to these kill thresholds.

Bugs
