The Engineer avenging his Sentry.
Sentry Buster

This article is about Community Anti-Sentry Buster strategy.

General

  • Sentry Busters are not a high priority target, and most of the time shouldn't be worried about over giant robots and sometimes regular robot, unless you're an Engineer.
    • Focused fire on the Sentry Buster can give the bomb carrier a chance to slip past your defenses without anybody realizing, and if you detonate a Sentry Buster right in the middle of a bunch of teammates, it forces your teammates to stop what they're doing and run from the blast radius. In the worst case, more than half of your team will be instantly wiped out by a single Buster.
  • You can attack the robot from afar, as well as with a melee weapon. It is only dangerous once it arms itself, either through loss of health, or reaching its target Sentry Gun.
    • This isn't totally true in Mannhattan; the security system that stuns the robots when a gate is captured can sometimes interact rather strangely with the Sentry Buster, allowing it to actually use its "weapon" (of which the icon is the Ullapool Caber) and may actually plow over any player it passes through. It's quite rare, but be forewarned.
  • Never let your guard down. It can and will use detours to reach its destination faster, if allowed to do so.
  • If a Sentry Buster begins to detonate, get as far away as possible. Note that at this point it cannot be affected by knockback.
  • Blast resistance reduce the damage taken from the explosion and gives you a possibility of surviving the blast in some cases, if you're fortunate and healthy enough.
    • However, do not upgrade Blast resistance only for this purpose. There are better things you can spend your money on most of the time, except for Scouts and money Spies.
  • Always listen to the sound of it arming itself. If you hear such a sound, stop what you're doing, find the Sentry Buster and if in its range, get away from it.
  • The explosion of a Sentry Buster also kills its allies. Use this to your advantage, if your team is having a hard time dealing with a horde of robots.
  • Unlike giants and many other robots, Sentry Busters cannot pick up the bomb. However, they run faster than most robots and cannot be body-blocked (An act of stopping a robot from progressing forward by standing in its path); Sentry Busters simply walk through a player as if they were a teammate.
  • There's a long lasting bug where Sentry Busters truly vanish instead of exploding. It plays the sound cue when arming itself as well as the explosion, but neither arming animation nor explosion are triggered. This mostly happens if the Sentry Buster is being hit by weaponry with snare effects, such as Natascha or a Rocket Specialist Soldier.

  • Sentry Busters shouldn't be a big threat to Scouts. You can safely escape the Buster's explosion radius with speed alone. The Scout should only be dealing with the Buster when there's no cash to collect and there's no robot to milk.
    • However, keep an eye on where the Sentry Buster is, otherwise you may accidentally run into a self-destructing Buster, right when you're turning around a corner. If it doesn't flat-out kill you, it will result in you losing most, if not all of your overheal buff.
  • Using the Force-A-Nature will knock back the Sentry Buster at close range and also knock you back, if you are airborne.
    • Be aware of where you knock the Sentry Buster to. You don't want to knock it straight into your Engineer's buildings, or your teammates.
  • Sentry Busters are not affected by stuns from the Sandman, since they're considered a giant robot. You can however still upgrade it with the "Ball Marks Target" upgrade, so players will do mini-crit damage.
  • Mad Milk will still affect the movement speed of a Sentry Buster if upgraded. A Sentry Buster coated in Mad Milk gives a maximum of 1500 health points to you and your teammates before dying. If there's no presence of a giant robot yet, you can consider milking the Sentry Buster.
  • The Fan O'War will allow you to tag the Sentry Buster for mini-crits. Use this to allow the rest of your team to focus down the Sentry Buster, but remember - only one target can be marked for death at any time and the mark will disappear faster for giants.
  • Sentry Buster can give you boost for the Baby Face's Blaster. Shooting them can build your boost back up quickly. Don't over-commit to getting boost however, as it could arm itself without a moment's notice or leave you distracted from more important Scout jobs.

  • If the Sentry Buster is too close to you and primed to detonate, you can rocket jump to do an emergency escape.
  • If you have 160 HP or less use Escape Plan to escape faster from the explosion. Although you may take 35% more damage because of mark for death, it's better to take extra damage than losing all your health. Better safe than sorry.
  • If you have a lot of teammates, consider equipping the Buff Banner, Battalion's Backup, or Concheror since Sentry Buster provides a good source of damage to build up rage.
  • Your Rocket Specialist upgrade is very useful against Sentry Busters. The upgrade allows you to stun and deal maximum damage to it. Keep firing until it is dead, but stay away from its blast.

Leaderboard class pyro.png Pyro

  • Your airblast is invaluable, so make sure to face the robot with full ammunition.
  • An easy way to alert your teammates of a Sentry Buster’s presence is to light it on fire and make it more noticeable, as well as damage it.
  • Critical flares shot from the Flare Gun or Detonator, and Axtinguisher or Postal Pummeler hits do critical damage when used in combination with air blasting - but remember that air blasting is the greater priority.
  • Max out the airblast force upgrade to push Sentry Busters back. If you can, you can knock them into an environmental hazard, such as a pitfall.
  • Although airblasting can save your teammate's lives and time, using them brainlessly creates more harm than helping.
    • Sometimes when Sentry Busters decided to self-destruct in mid-air, it only plays the sound but doesn't play the self-destructing animation. This can be very confusing especially for new players and thus can create an unexpected death.
    • Your team's Engineer should be ready to deal with the Buster. Airblasting just to buy him time can end up making him waste more time, waiting for the Buster to reach him.
    • A bouncing robot is almost always harder to hit than a robot traveling in its predictable path. Overusing airblast can make it harder for teammates to deal with the Buster and a living Buster can accidentally block incoming fire for other robots, as well as distract teammates from dealing with other threats.
  • Due to the Sentry Buster's large health pool, you can get a considerable amount of Mmmph with the Phlogistinator. Chase them down to get as much Mmmph from them as you can when there's no other way of building Mmmph faster or engaging other robots to build Mmmph is too risky.

Leaderboard class demoman.png Demoman

  • Demoman doesn't profit too much from the presence of the Sentry Buster, and thus they should avoid shooting the Buster when there's other robots to take down.
  • With the Scottish Resistance, you can plant extra stickies near an Engineer’s nest. If the Sentry Buster gets near, detonate them to weaken and hopefully kill it right away. Just make sure not to put them too close, that the robot will still be in range of the buildings.
  • Use the Chargin' Targe, Splendid Screen, or Tide Turner to escape the explosion if you're caught right next to them.

Leaderboard class heavy.png Heavy

  • Stand on the Dispenser and help defend the Engineer with your Minigun.
  • Natascha slows down Sentry Busters immensely. Use it if you have surplus time to keep the Sentry Buster pinned.
    • The damage penalty can make killing other robots harder, however.
  • Sentry Busters have a large health pool. You can build a considerable amount of rage from each one.
  • The Gloves of Running Urgently can be used to escape the Sentry Buster if it detonates near you.
  • The Fists of Steel may provide damage resistance against explosions, but even combining it with maxed out blast resistance barely gives you much chance of surviving the blast.
  • The Holiday Punch's critical hit forces the Sentry Buster to taunt. The animation that the Buster plays is simply an idle Buster standing still. This buys your teammate some time to shoot the Buster. However, the Sentry Buster will detonate immediately after a set amount of time without giving any warning, and can result in some players dying without them even knowing what happened.
    • If you're playing as another class, simply keep your distance and allow the Heavy to work while you chip away at it.

Leaderboard class engineer.png Engineer

  • Sentry Busters are there just because of you, and it's mostly your job to deal with them, not your team.
  • It's not your team's responsibility to kill the Buster for you. Do not pick your Sentry up and run around the map, just to buy your team some time to destroy it. Most of the time, they have more important things to do and you not being at your post could be their undoing.
  • Put your other buildings far away from your main Sentry Gun. This will allow them to stay intact even if your Sentry is destroyed.
  • As soon as the Sentry Buster comes to your Sentry and starts preparing to detonate, grab your Sentry and run as fast as you can. Note that grabbing a Sentry too late will cause you and your Sentry to be destroyed. The Rescue Ranger reduces this risk, by allowing you to wait until the Sentry Buster approaches your Sentry Gun, then grabbing it from afar as it arms itself.
    • If you have a bit of free time, you can simply grab your Sentry, run to the Sentry Buster and touch it, then move away from the explosion. This saves you more time because you don't have to wait for the Sentry Buster to detonate to put the sentry down in your regular spot.
    • If you are standing near an edge, try to fall off it with your Sentry Gun. Note that a horde of other robots may be under the cliff, so plan your retreat.
    • If your Sentry was placed near a corner, pick up your Sentry and run around the corner once the Sentry Buster starts to detonate. The wall will protect you and your Sentry from the Sentry Buster’s explosion.
  • There are locations on some maps where Sentry Busters will take a while to reach, as they cannot jump. Know those locations so you can stall the Sentry Buster and time your escape.
  • If there is more than one Engineer on the map, you should refrain from Sentry Stacking (Placing your main Sentry Guns next to each other), to prevent a single Sentry Buster from destroying all of them.
  • Having only 1 Engineer is advised because the appearance of multiple busters at once may confuse which Buster targets which Sentry Gun.
  • Wrangling your Sentry will not shield it from the explosion.
  • Use your Übercharge Canteen to protect you and your Sentry from the explosion as a very last resort. Note that it will not protect your other buildings.
  • Make sure your buildings are not in the way of the path of the Sentry Buster, otherwise they will get destroyed since the Sentry Buster can simply walk through them and trample them, no matter how much health they have.
  • When dealing with Sentry Busters, make sure you detonate them behind the team's defense and not in the middle of a bunch of teammates. Pick up your Sentry and let the Buster self-destruct away from the front line.

Leaderboard class medic.png Medic

  • Because the Übersaw gives you 25% charge when you score a successful hit against a Sentry Buster, experienced Medics can gain a large amount of charge with a single Buster and charge his teammates with uber/crit/mega-heal/resistance more often. Thus, if dealt with correctly, the Sentry Buster can benefit the Medic way more than harming him.
    • However, do not chase the Buster if you or your team have to risk dying, due to your moving away from your section. Remember, dead teammates will weaken your defensive line, and dying yourself destroys all your charge unless using the Vita-Saw, which will salvage 19% of it.
    • It is advised not to attempt this when you already have a shield deployed. Switching away from your Medi Gun disables the shield and it cannot be reactivated until the shield meter completely empties. Balance out the cost to decide whether to build your charge or keep your shield running. Remember, keeping the shield running can save many of your teammate's lives and thus benefits your team more when there's a swarming amounts of incoming projectiles.
  • If you're using the Vaccinator don’t hesitate to use your resistance in dangerous situations on the Engineer or yourself.
  • If you're caught with the Sentry Buster right next to you and it's about to explode, popping your Übercharge (Or Über canteen, if you're using the Quick-Fix, Kritzkrieg, or Vaccinator) can save you from dying and losing all your charge. Pop it, don't drop it.

Leaderboard class sniper.png Sniper

The hitboxes of a Sentry Buster.
  • While it doesn't look like it, Sentry Busters do have head hitboxes that are sensitive to headshots. Hitting the very topmost pin of the Sentry Buster will do headshot damage.
    • Upgrading explosive headshot slows the buster if you score a successful headshot. More points in the upgrade means the Buster will be slowed more, you will hit more nearby robots, and the slow effect last longer. It will also damage robots around the Buster.
    • They're one of the hardest robots to score headshots with due to their incredible speed and their "invisible" head. Focus your shots carefully or target other threats, if you have no time to work on it.
  • The best and most effective means of helping your team would be to throw Jarate on a Sentry Buster. With slowdown upgrade, you can reduce the Buster's speed to a crawl and make scoring headshots on them far more easier.
    • In particular, the Bushwacka can wreak havoc on a Jarate'd Sentry Buster. Though again, worry about other threats, if they're present.

  • Sapping the Sentry Buster kills most of their speed for a short period of time. Make sure to sap it as soon as your teammates can attack it effectively. Otherwise, save it to sap higher priority targets such as Über medics.
    • Working with a Medic, you can sap the Sentry Buster and then signal the Medic to use his Übersaw on it to gain charge, if he is lacking a full charge.
    • Sapping a Sentry Buster can buy the Engineer more time to either pick off more robots before dealing with the Sentry Buster, or to reach his Sentry Gun to pick it up, if he is not close enough or respawning.
  • Sentry Busters cannot be backstabbed, as made obvious by the lack of a back to stab. They can still be headshot with the Ambassador if you hit the top pin, like a Sniper.
  • Remember, the Sentry Buster will explode when its health runs out, so give yourself time to get clear of the blast. If that isn't possible, the Dead Ringer can save you from death by the Sentry Buster's explosion, though this should only be used as a last resort, as it means you will have to get it recharged before going back to work on the robots.
