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 monowheel robot with a titanium alloy frame. Its form is vaguely humanoid, with two flexible arms and pincers for hands. On the front side is an image of a face, indicating the unit's purpose and alert status.

Each comes with a set of four weapons mounted on its arms: a 9mm submachinegun for close range suppression and crowd control, a Glastinghouse, Inc. X-25 Gatling laser against soft targets at medium range, M-235 rocket launcher for ground and air targets at long ranges and a rapid fire G-28 grenade launching system to enhance its lethality in close-range engagements.

With only the Mark I operating system installed, the unit is unable to make use of the rocket and grenade launchers. In this state, the unit's face is that of a policeman. If upgraded to the Mark II operating system, all weapons become operational and the unit's face becomes that of a soldier.

Interactions with the player character
In Fallout: New Vegas, PDQ-88b units are the hands and eyes of Mr. House and roam the New Vegas Strip enforcing his law. Notably, they guard the entrances to the Strip. Victor frequently appears in the main quest line, and Jane takes Snowglobes from the player to be placed in Mr. House's collection.

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

Appearances
The PDQ-88b appears in Fallout: New Vegas.
