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.
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 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 only 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 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 combat effectiveness of each Securitron unit is improved by 235% by the upgrade.
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.
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.
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 build-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 an American Army infantryman.
They are a new line of Securitrons created in Big MT by 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.
The unit's face of the berserk PDQ-88b Securitron is a distorted face, similar to the "angry moon" public domain clip art. 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.
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. Oddly, the Damaged Securitron's face is still lit up when destroyed.
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 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 with the exception of Muggy.
With a Science skill of 80 or greater, the player can input the following code when attempting to enter the New Vegas Strip: 1C 3C R34 M. This is "L33T-speak" for ice cream. Ice cream is also the code word used to identify third floor access at REPCONN Headquarters.
When deactivated via Robotics Expert perk, they will still move but cannot be interacted with. This is an issue present with many of the other robots in the game.
Outside of the Ultra-Luxe, three female NCR troopers are dancing in the water fountain, two in their underwear and the other wearing sexy sleepwear. Two Securitrons will be telling them to leave, while getting more and more hostile. Eventually, two male NCR MP's will arrive and disperse the women.
Two Securitrons can occasionally be seen outside of New Vegas Boulevard Station, puzzled by a piece of graffiti on the wall. They fire their Gatling lasers at it in attempt to clean it off, although this is futile and nothing actually comes off.
Securitrons seem to have police sirens in the opening cinematic. In game, they do not ever actually use their sirens.
