'''Sentry Guns''', also known as '''Turrets''' or '''Sentries''' are a [[Buildings|Building]] type built by the [[Engineer]]. Just like other Buildings (except the [[Jump Pad]]) they have 3 levels, and each level costs 200 metal to upgrade. The Gun itself is a device on a tripod constructed of metal and team colored-paint and locks on to enemies with perfect accuracy.

A level 1 Sentry Gun is an automatic single machine gun with an internal magazine with a team-colored top with a team-colored light to the left side of the barrel.

A level 3 Sentry Gun is identical to level 2, except for a rocket launcher which comes out of the top of the Sentry Gun and fires 4 rockets at once.

The Sentry Gun is a powerful force for area denial. The Sentry Gun has perfect accuracy and an incredible amount of damage potential, as well as noticeable knockback. It locks on to the closest target within range and line of sight and opens fire until the threat is out of sight, out of range or neutralized. A well-placed Sentry Gun can singlehandedly defend [[Attack / Defense|a control point]], an [[Capture the Flag|intelligence briefcase]] a [[Payload| Payload cart]] or anything else.

However, they take significant time to set up, have limited range, are not very mobile, and can be easily destroyed via an [[Übercharge]] push, a [[Spy|Spy's]] [[Sapper]], the [[Demoman]] or any significant source of damage from range. Even the [[Scout|Scout's]] [[Pistol]] can destroy an unattended Sentry if he finds the right spot to shoot from.

The Sentry Gun costs 130 [[Metal|metal]] to build, by far the most expensive Building for the Engineer to construct, and just like any other Building (except the Jump Pad) it takes 200 metal to increase to the next level, totaling in 530 metal to fully construct and upgrade a Sentry. With each level the Sentry Gun becomes stronger, gaining additional guns, rockets and [[Health]]. However, the range does not change with level. The Sentry Gun's health and [[Ammo|ammo]] can be replenished by any allied Engineer hitting it with a [[Wrench]]. This allows a team with multiple Engineers to all support each other. Allied Engineers, however, cannot move another Engineer’s Sentry.

When a Sentry Gun is placed, it starts with 0 health but like all Buildings it gains health as it constructs. This continues until it reaches its maximum health. Any Sentry Gun routinely rotates 90 degrees around itself, however it will lock on any enemy entering its range, even if it was behind the Sentry Gun. However, the Gun turning takes some time, which can allow enemies to slip through. The Sentry Gun beeps as it turns, and the beeping increases with level upgrades. Experience players can use this to detect a Sentry Gun before seeing it and know its level before engaging.

When a Sentry Gun is hauled and placed down again, it must go through its construction and upgrade animations before it can function, similarly to a teleporter. This makes a level 3 Sentry ill-suited for offensive situations where the fight is constantly moving, such as offense on Payload maps, as a Sentry Gun that is re-constructing itself is a very easy target.  If the fight is constantly moving or the Engineer is on offense, an Engineer can consider simple using a level 1 Sentry that can be easily moved around as needed. If an Engineer is killed while hauling a Sentry (or any Building) it gets destroyed with a special kill icon.

The [[Minigun]] has a unique 15% damage penalty against level 2 Sentries and a 20% damage penalty against level 3 Sentries.

Line 34: Line 36:
Sentries have various vulnerabilities players can exploit to negate its damage or destroy it. A weapon fired at a Sentry Gun does not suffer from damage fall-off, allowing an enemy player to destroy it even from long distances. A destroyed Sentry drops metal parts which can be collected by any player as ammo or metal.

Sentries will not fire on [[Cloak|cloaked]] or [[Disguise|disguised]] [[Spy|Spies]]. However if a Spy disguises while it is being targeted by a Sentry, it will continue firing unless the Spy breaks line of sight or escapes it’s range. The Sentry will also not fire if the enemy is hidden behind cover, even if they are in the Sentry Guns range. Sentries are also not able to fire if they are being [[Sapper|Sapped]] or if they are in the middle of being constructed/upgraded.

Engineers are also able to take self-damage from their own Sentry. Engineers looking to avoid this can stand behind their Sentry Gun and not in front of it.
