Securitron

The PDQ-88b securitron (also named the RobCo security model 2060-B) is a private security robot created and mass-produced by House Industries with the help of RobCo Industries, and privately and on a much smaller scale by the Big MT research company, who were primarily attempting to improve the original. They are commonly found patrolling The Strip. They can also be found around Big MT and inside the Lucky 38.

Characteristics
The PDQ-88b securitron is a 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 a Glastinghouse 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 only secondary weapons; concealed compartments in 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 produced by 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 explosive weapons, limiting the robot's arsenal to the built-in X-25 Gatling laser and the 9mm machinegun. 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 upgrade improves the combat effectiveness of each securitron unit by 235%.

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

House Industries
These are the models 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 submachine gun, but it cannot use its auto-repair systems. The unit's face is that of an American policeman.

* 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 1s have grenade launchers instead of X-25s, and will use it frequently despite them supposedly not having the software drivers for them.

Mark II
Through the use of the platinum chip, the Courier may upgrade the securitrons of Mr. House or Yes Man at The Fort and around The Strip to the Mark II operating system. The Securitron Mk II can use all the built-in weapons: the 9mm submachine gun, the rapid-fire G-28 25mm grenade launcher, the M-235 missile launchers, and the X-25 Gatling laser system. However, outside of the Lucky 38 basement demonstration, it only ever uses the last 3. It can also use the auto-repair systems, and its armor is increased. The unit's face is that of a American soldier wearing an M1 Combat helmet and smoking a cigarette.

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 irreparably damaged or have gone berserk due to lack of maintenance for over 200 years, also now lacking any functional armor.

Berserk series
The face of the berserk PDQ-88b securitron unit is a distorted face, similar to the "angry moon" featured in the film A Trip to the Moon. The berserk model has the ability to use the rocket launchers in its shoulders and the laser in its arm, but not the grenade launcher or machine gun.

Damaged series
The unit's face of the damaged PDQ-88b securitron is the berserk one's face crossed out. It can use the grenade launcher and machine gun, but not the other weapons.

Other interactions
Securitrons in the Mojave Wasteland are the hands, eyes and soldiers 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 Courier 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 Courier, with the exception of Muggy.

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 This is a reference to RoboCop, who uses the same line.
 * Likewise, if the Courier chooses to frame Heck Gunderson for his son's murder during the Beyond the Beef quest, the securitron will say before shooting him dead.
 * When in combat, Securitrons guarding The Strip North Gate will occasionally say This is a reference to the Daleks from Doctor Who.

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.
 * The securitrons may sometimes keep swapping weapons without even attacking the enemy.
 * 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.
 * It is possible that opening Mr. House's Antechamber may only cause a couple of his securitrons in his penthouse to become hostile, even after destroying some of them.
 * Its possible that none of the securitrons will become hostile when opening Mr. House's antechamber.
 * The securitrons at the Battle of Hoover Dam (if you fought for an independent New Vegas) will not switch from their shoulder mounted rocket launchers, often blowing themselves up within minutes of the battle. However, if you side with House, this does not happen.
