Securitron

The PDQ-88b Securitron (also named RobCo security model 2060-B), is a private security robot created and mainly produced by House Industries with the help of RobCo Industries, and privately by the Big MT company. Its form is vaguely humanoid, with two flexible arms and claw-like pincers in place of hands. Despite that, their hands are not suited to use tools and weapons usable by humans. On the front side is a screen displaying an image of a face, indicating the unit's purpose and alert status. When killed, the screen will freeze in whatever position it was in when it was destroyed.

Characteristics
The PDQ-88b Securitron is a fairly large, monowheel robot with a titanium alloy housing, resistant to shrapnel and small arms fire. The PDQ-88b Securitron is heavily-armed. Its left arm contains its primary weapon, a Glastinghouse, Inc. X-25 Gatling laser for medium range engagements. For close-range suppression and crowd control, the Securitron mounts a 9mm machinegun in its right arm. However, these are both secondary weapons: concealed compartments on its shoulders contain M-235 missile launchers for long range and surface-to-air engagements, and a rapid-fire G-28 grenade launching system for close range engagements. The robots also have onboard auto-repair systems to repair any damage sustained from combat. Thus armed, a Securitron can handle nearly any combat situation.

The PDQ-88b Securitron of House Industries supports only two operating systems: Mk I and Mk II. The Mk I operating system lacks drivers for the auto-repair systems and shoulder-mounted weapons, limiting the robots' arsenal to the built-in X-25 Gatling laser and the 9mm cannon. The Mk II operating system enables the M-235 missile launchers, the rapid-fire G-28 grenade launching system and the auto-repair system. As estimated by Mr. House and Yes Man, the combat effectiveness of each Securitron unit is improved by 235% by the upgrade.

The PDQ-88b Securitron of Big MT supports six operating systems: Mk I, Mk II, Mk III, Mk IV, Mk V and Mk VI. These increase gradually firepower and accuracy, efficency of auto-repair systems and missile launcher capacity.

House Industries
They are the model created by House Industries, the original creator of the PDQ-88b Securitron, with the help of RobCo Industries. After the Great War, they are almost all controlled by Mr. House and can be upgraded via the platinum chip.

Mark I
The Securitron Mk I can only use the X-25 Gatling laser and the 9mm cannon, and it can't use its auto-repair systems. The unit's face is that of a policeman.

* Possibly due to developer oversight, the Securitron Mk I's on the Strip have a DT of 0. The Securitrons in Freeside and inside the Lucky 38 have the normal DT of 20.

Mark II
Through the use of the platinum chip, the Courier may upgrade the Securitrons of Mr. House at The Fort and around The Strip to the Mark II operating system. The Securitron Mk II can use all the weapon available as the X-25 Gatling laser, the 9mm cannon, the M-235 missile launchers, the rapid-fire G-28 grenade launching system and can also use the auto-repair systems. Its armor is increased and the unit's face is that of an American Army infantryman.

Big MT company
They are a new line of Securitrons created in Big MT by 0|Doctor 0 and his team, to surpass the PDQ-88b Securitron created by House Industries and Robert House (the latter considered by 0 to be his greatest enemy). These efforts succeeded to a degree, as a Mk VI Securitron operating system was developed. However, these never reached full production and as of 2281, all of Big MT Securitrons are either irreperably damaged or have gone berserk due to lack of maintenance for over 200 years, also now lacking any functional armor.

Berserk
The unit's face of the berserk PDQ-88b Securitron is a distorted face, similar to the "angry moon" public domain clip art.

Damaged
The unit's face of the damaged PDQ-88b Securitron is the berserk one's face crossed out.

Other interactions
Securitrons in the Mojave Wasteland are the hands and eyes of Mr. House. Notably, they patrol the Strip and guard its north entrance. Like all robots, Securitrons cannot be pick-pocketed, and attempting to do so will just trigger the Securitron to say one of their quotes. The player may upgrade the units to the Mark II operating system through the use of the platinum chip.

Those of Big MT, however, are all hostile to the player.

Appearances
PDQ-88b Securitrons appear in Fallout: New Vegas and the add-on Old World Blues.

Behind the scenes

 * If the courier has taken the Wild Wasteland trait, Securitrons may say "Your move, creep!" This is a reference to RoboCop, who uses the same line. Likewise, if the player chooses to frame Heck Gunderson for his son's murder during the "Beyond the Beef" Quest, the Securitron will say "Dead or alive, you're coming with me" before shooting him dead.
 * When in combat, Securitrons will occasionally say "Exterminate!" This is a reference to the Daleks from Doctor Who.
 * The Berserk Securitrons in Old World Blues (add-on) have a face similar to a piece of clip art known as "Angry Moon". This piece of clip art was taken from the cover of sheet music to the song "Stingy" by J. Fred Helf and Ed. Gardenier published in 1904.

Bugs

 * While inside The Strip, if you kill a Securitron with a head shot and destroying its TV monitor, the screen will still be present but the surrounding edges around the screen shows that the screen was destroyed.
 * One of the Securitron Gatekeepers (top right) will be missing from its post when fast-traveling or just heading regularly to the Strip's gate. It can be found in an alleyway to the east of the gate, seemingly stuck between a light post, a dumpster, and the wall of the building to the north. Pushing it from this spot will cause it to roll back to its post. What causes this is unknown, but it may be that the robot spawns in the said position.
 * The Securitrons may sometimes keep swapping weapons without even attacking the enemy.
 * The Securitron's, both Mk I and Mk II, pathfinding skills and ability to engage the enemy is so that they often get stuck in their location or refuse to move and shoot at hostile targets.
 * Sometimes, companions will attempt to talk with a Securitron, even though Securitrons have no greeting dialogue. For example, it will reply: "Please, do not stand in the fountains" when greeted hello (or similar). Occasionally, your companion will stay there indefinitely until you talk to the Securitron AND your companion.
 * When passing the Science check with the Securitron Gatekeeper, and talking to it again saying goodbye, the Securitrons might turn hostile while attempting to enter the Strip.
