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. Privately and on a much smaller scale, another model was produced 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.
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 GlastinghouseX-25 Gatling laser for medium range engagements, while its right arm contains a 9mm machinegun for close-range suppression and crowd control. 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.
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.
* 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.
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 an American soldier wearing an M1 combat helmet and smoking a cigar.
There is 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. Because of this, they lack any functional armor, as well..
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.
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 lines. 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.
With a Science skill of 80 or greater, the Courier 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 the 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.
The securitrons in the Las Vegas Boulevard Station and in front of the water fountain, will still be Mk I, regardless of any upgrades given to the other securitrons.
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.
According to Father Elijah, they are said to have come from the Big MT.
If there is an NCR Ranger or trooper following the Courier, the securitrons by the Strip will shoot them.
Securitrons have a small plate just beneath their monitors that reads H&H Tool Company, implying a relation to Anthony House (Robert House's half brother).
Killing the securitrons at the Strip's gate will cause all securitrons to become hostile.
The securitrons at Big MT use the same Robco terminal symbols as Dr. 8, which can only be seen with the subtitles turned on. The securitrons will also make a beeping sound when this happens rather than Dr. 8's static sound.
It appears that they have the ability to switch AI "personalities" (I.E. Victor and Yes Man) from one securitron to any other, as Victor is seen welcoming the Courier if he goes to the Strip via NCR Monorail, and then immediately switching back to a standard securitron guard robot AI.
