The Engineer with a Level 3 Sentry
How am I going to stop some big mean mother hubbard from tearing me a structurally superfluous new behind? The answer: use a gun. And if that don't work... use more gun.
The Engineer


The Sentry Gun (sometimes known as a "Turret", "Sentry" or abbreviated to "SG") is a building that can be constructed by an Engineer and functions as an automated turret which fires upon any enemy who walks into its line of sight. The Sentry Gun will always target and fire on the closest enemy player or building, provided they are within firing range and in line of sight of the Sentry Gun (not behind a wall, etc).

The Sentry Gun costs 130 Metal to build, 200 Metal to upgrade to level two, and an additional 200 to upgrade to the third and final level. With each upgrade level the Sentry Gun becomes more powerful, gaining machine guns, rockets and the ability to take more damage. The firing range remains constant regardless of level.

The Sentry Gun's ammo may be replenished with your own metal by hitting it with your Wrench. Each bullet reloaded costs 1 metal and each rocket salvo costs 2 metal.

When placing a Sentry Gun, the limit of its range is represented by a 3D sphere of your team color. A Sentry Gun that is being constructed will have its health increase gradually until it reaches its maximum health upon completion. The Sentry Gun rotates 90 degrees to patrol the area, but is capable of rotating 360 degrees to lock on to a target. This takes a brief moment however, which may allow faster foes to slip past its range. The Sentry Gun can also be manually rotated to face a different direction before you build it: When the blueprint is shown, using the alternate fire button (default key: MOUSE2) will rotate the blueprints counter-clockwise by 90 degrees.

Sentry Guns will not fire upon enemy Spies that are cloaked or disguised. Sentry Guns are also unable to fire if an enemy Spy attaches an Electro Sapper to it or while they are being upgraded/built. A destroyed Sentry Gun leaves 60 Metal worth of pieces, which can also be picked up by other classes as Ammo.

Unlike most other weapons, the Sentry Gun's weapons do not get affected with damage falloff from range nor can it gain criticals. It is possible however, to make the Sentry Gun deal Mini crit attacks and damage if its target is coated in Jarate or if the Engineer who built the Sentry Gun is close to a Soldier with an active Buff Banner, boosting the damage of each bullet to 22.

Since the Engineer Update, players are able to pick up and move their Sentry Guns around. The Sentry Gun retains its level after being transported in the Toolbox.

Also included in the Engineer Update is an unlockable Pistol replacement, The Wrangler, which allows the Engineer to take direct control of his Sentry Gun by 'marking' targets manually. Doing so shuts down the Sentry Gun's automated target-lock system, but diverts the excess power from the targeting system into speeding its firing rate, effectively doubling the damage-per-second of the Sentry Gun. Also, the Wrangler provides the Sentry Gun with a protective Shield, which absorbs two-thirds of enemy fire while the Wrangler is active. Once the Engineer shuts off and pockets the Wrangler, however, his Sentry Gun is left defenseless for 3 seconds while its auto-lock targeting computer reboots.

since the new update all level sentry's can be replaced when fully deployed. when the engineer carries his sentry or other building he goes around the speed of a heavy. he can not fire or change weapons. when he gets killed also his building gets instantly killed. this gives as "destroy picture" a engineer box with a explosion. a redeployed sentry automatic goes to his previous level. he builds 2-3 times faster then normally. he does not lose ammo or gains ammo by doing this. also a redeployed sentry has no health at start of the build. just like a normal sentry. once it has been deployed it will automatic start firing or start the wrangle fire. sapped buildings can not be redeployed.


Combat Mini-Sentry Gun

A RED Mini-Sentry Gun
Sometimes, you just need a little less gun.
The Engineer

The Combat Mini-Sentry Gun is a more combat-efficient version of the standard Sentry Gun, and is a component of the Engineer's Gunslinger unlock. The Combat Mini-Sentry Gun has several advantages: it costs only 100 metal to place, constructs at four times the speed of the original Sentry Gun, is deployed at full health and fires 50% faster than a Level 1 Sentry Gun. However, it is neither repairable nor upgradable, as it is intended for short-term use rather than long-term area denial fortification. It also deals only 50% the damage per shot of the original Level 1 Sentry Gun.

like any other sentry gun it can be replaced after it has been fully deployed. redeploying does go faster like the normal sentry gun. not really needed anyway.

the mini-sentry is easier to see because it has a small alarm light on the top of the mini-sentry.

Trivia

  • The original Sentry Gun designs were created by Radigan Conagher in 1890 [1]. The original and current designs are visually identical.
  • The Engineer apparently designed and built the final version of the Sentry Gun under contract from 'TF Industries' in 1965.
  • The official game manual for Team Fortress 2 is actually the Sentry Gun Operating Manual.
  • Engineers can receive a "Sentry Gunner" achievement for racking up 10 kills with a single Sentry Gun; the Engineer can die, as long as the Sentry Gun does not.
  • A label on the Sentry Gun blueprint reads "Automatic Sentry Gun Aparatus;" however, the Sentry Gun manual refers to it as a "Sentry Gun Mechanical Firing Device".
  • Like all Buildings, Sentry Guns can be built underwater.
  • Sentry Guns cannot fire through a Dispenser built by an Engineer of the same team.
  • The Sentry Gun makes a number of beeps every time it reverses its rotation. The number of beeps corresponds to its upgrade level, where a level 3 turret makes three quick beeps. Additionally, the higher the Sentry Gun's level, the louder it is. A level 1 Sentry Gun is slightly harder to hear than a level 3 Sentry Gun; this fact can be used to counter enemy Sentry Guns.
  • When out of ammunition, a Sentry Gun will continue lock on to enemies and attempt to fire, but will instead make clicking sounds.
  • Engineers can reach higher standing on a level 1 Sentry Gun than with a Dispenser, making it a better choice on jump and puzzle maps.
  • Due to a bug, the rockets from a Sentry Gun may sometimes damage teammates if the Sentry Gun is destroyed as the rockets are in-flight.
  • An unused alternate kill icon for the level 1 Sentry Gun exists in the game files, seen to the right.
Unused level 1 sentry kill icon
Oldesentry.PNG
  • When the Wrangler was added in the Engineer Update, all levels of Sentry Gun were given laser sights to accommodate it.
  • A bug existed where level 2 and 3 Combat Mini-Sentry Guns could be built by building a normal Level 2 or 3 Sentry Gun, switching to the Gunslinger and hauling and redeploying the existing Sentry Gun. The result of this was a miniature version of the Level 2 and 3 Sentry Guns that gained the properties of the Combat Mini-Sentry, such as the 75% damage and the 4x build speed. These Sentry Guns would always appear to be on the RED team but their characteristic light effect would glow their proper team color. This bug has since been fixed.
  • When using the Wrangler, the Sentry Gun's laser will auto lock on (aim assist) to targets when you move your crosshairs near them.
  • An image appearing on the Engineer Update page possibly show very early designs of the modern Sentry Gun.
  • The flashing light on the Combat Mini-Sentry Gun appears to be attached with duct tape. It appears to be identical to the flashing light on the Bomb Cart in Payload maps. This light also appears to be duct-taped on.
  • Feign deaths produced by the Dead Ringer will not be added to the Sentry Gun kill/assist counter.
  • if a sentry is redeploying he gets a milisecond between it goes from level 1 to level 2 (and 2 to level 3). enough time to start the wrangle shield or a beep that it sees enemies.
