Turrets: Difference between revisions

'''Sentry Turrets''' are tripod robots that appear in every game in the ''Portal'' series. They are seen as incapable of independent movement, but can open each side of their chassis (their 'arms') horizontally in order to reveal twin double-barreled machine guns. The central part of the chassis holds their red eye, which emits a targeting laser. Almost all of the space within the Turret is devoted to storing the ridiculously stacked ammo, explaining the nearly infinite supply of ammo when firing. According to the ''Portal 2'' Turrets trailer, the turrets use spring mechanisms to accelerate the whole bullet, including the casing, which may explain how the player can survive getting shot by the Turret so many times and to quote Cave Johnson "They fire more bullet per bullet."

 

In Portal, Turrets will shoot the bulletproof glass and portals when the player is on the other side. In Portal 2, however, Turrets will only follow the player behind glass with their beam and not shoot through portals, opening fire almost immediately when the player moves out of the glass or through the portal. In addition, Turrets appear to be unable to see through [[Hard Light Bridge]]s or [[Excursion Funnel]]s.

In the game's [[co-op]] campaign, the Defective Turrets appear as obstacles for [[Atlas]] and [[P-body]] throughout the ''Mobility Gels'' testing course. These Turrets appear to be as fully functional as regular Sentry Turrets and possess the innocent and feminine voice tones as they should. The only difference from regular Turrets is that they have been defaced. This is most likely because [[Aperture Science]] had not yet developed the modern casing. {{spoiler|One Defective Turret in the final test chamber of this test course has been evidently reconfigured by someone, as instead of serving as a typical testing obstacle, before dying it reveals that it "needs to protect the humans".}}

Frankenturrets do not speak, and instead emit incomprehensible chirping sounds. They generally serve as {{spoiler|Wheatley's}} replacement for Storage Cubes {{spoiler|once [[Chell]] is available as his test subject}}. They are harmless, and the only difference from normal cubes being that Frankenturrets will hop around aimlessly when not placed on a [[Heavy Duty Super-Colliding Super Button|button]]. When picked up by Chell, they retract their legs inside the cube. If they fall over on their sides or upside down, they will wave their legs trying to get up.

{{spoiler|Apart from the ending, a Prima Donna Turret can also be found in the chapter ''The Return'', at the end of Test Chamber 11; briefly seen taking a lift upwards just as [[Chell]] enters the [[Chamberlock]]. It can also be found below the [[Doug Rattmann|Rattmann]]'s den in the same chapter during Test Chamber 16, where it is observing or lecturing a turret quartet.}}

The '''Animal King Turret''' is a unique type of turret in the single-player campaign of ''Portal 2'' that is only used in an Aperture Science slideshow to represent an "Animal King Takeover" in the chapter, ''The Courtesy Call''. The Turret is considerably colossal in comparison to its Sentry Turret brethren, and appears to operate the 'arms' on its side in exactly the same way.

The '''Hover Turret''' is an unused Turret found within the game files of ''Portal 2''. It uses the model of the [[Curiosity Core]]. It emits a laser, similar to the other types of Turrets, that is coloured light-blue, similarly to the Rocket Turret's targeting laser, and is able to burn the player similar to the burn of the [[Thermal Discouragement Beam]], however unlike the Thermal Discouragement Beam its laser does not provide a barrier for the player's movement, nor does it interact with game mechanics. The Hover Turret can be spawned within ''Portal 2'' via the cheat command <code>ent_create npc_hover_turret</code>, although it lacks a model by default, resulting in it appearing as a bright blue ERROR.

Turrets are introduced as testing hazards to [[Chell]] during the entirety of [[Portal Test Chamber 16|Test Chamber 16]]. Following this, they continue to appear throughout the remaining test chambers and eventually, during Chell's escape.  

* The shipping box for the Turrets states that one of the blue painted Turrets was bought on January 25, 2010 by a person with an unreadable name. The reference to Michael Jackson can be seen on the box.{{Citation needed}}

* The Rocket Core from Portal was originally intended to fire lasers instead of rockets, but playtesters thought that a rocket would be more dramatic than a laser slowly melting the glass.

* Turrets fire the whole bullet, which "is 65% more bullet per bullet"<ref>[https://www.youtube.com/watch?v=6i-nMWgBUp0 Aperture Investment Opportunity #3: "Turrets"]</ref>
