Securitron

, or RobCo security model 2060-B, is a pre-war robot produced by RobCo Industries. In Fallout: New Vegas, they are encountered mostly in and around the New Vegas Strip.

Characteristics
The PDQ-88b is a fairly large, monowheel robot with a titanium alloy housing, resistant to explosive shrapnel and small arms fire. Its form is vaguely humanoid, with two flexible arms and pincers for hands. On the front side is a screen displaying an image of a face, indicating the unit's purpose and alert status.

Its left arm contains an X-25 Gatling laser for medium range engagements. Its right arm contains a 9mm SMG for close-range suppression and crowd control. 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.

The PDQ-88b supports two operating systems: Mark I and Mark II.

Mark I
The standard Mark I operating system lacks drivers for the auto-repair systems and advanced weapons, limiting the robots' arsenal to the Gatling laser and submachine gun. In this state, the unit's face is that of a policeman.

Mark II
Through the use of the Platinum Chip, the Courier may upgrade Securitrons at The Fort and around The Strip to the Mark II operating system. Once upgraded, all weapons become operational, the auto-repair systems are engaged, and the unit's face becomes that of a soldier. It is stated that Mark II Securitrons are 235% more effective per unit in combat than Mark I Securitrons.

Interactions with the player character
PDQ-88b units are the hands and eyes of Mr. House. Notably, they patrol the Strip and guard its north entrance.

Victor and Yes Man frequently appear in the main quest line. Jane buys snowglobes from the player to be placed in Mr. House's collection.

The player may upgrade the units to the Mark II operating system.

Behind the scenes

 * Securitrons may say "Your move, creep!". This is a reference to RoboCop, where the same line is said. Likewise, if the player choses to frame Ted Gunderson during the "Beyond the Beef" Quest, The Securitron will say "Dead or alive, you're coming with me" another RoboCop line.
 * When in combat, Securitrons will occasionally say "Exterminate!" This may be a reference to the Daleks from Doctor Who, but it is more likely to be a reminder that Securitrons are robots.
 * The Securitron's arms, shoulders and placement of their face screens are strongly reminicent of the Martian invaders from George Pal's 1953 film The War of the Worlds. This would be in keeping with the game's 1950's retro stylings.
 * Their flashing vocorder plates bear a strong similarity to the B-9 Robot from the classic sci-fi series Lost in Space

Appearances

Bugs

 * While inside The Strip if you kill a Securitron and destroy the TV monitor, leave and return the screen will appear to be on 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.
