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 Securitron Mark I Operating System installed, the unit is unable to make use of the rocket and grenade launchers. If upgraded to the Securitron Mark II Operating System, all weapons become operational.

Securitron Mark I Operating System
This standard operating system allows the Securitrons armor to deflect more small arms fire and shrapnel. The Mk I displays a policeman for a face. The weapons this OS allows are fairly unimpressive but are as follows:


 * 9mm submachinegun
 * Frag grenades

Securitron Mark II Operating System
It is activated by inserting the Platinum Chip into the computer in the Securitron Vault located at The Fort, and uploading the data.

The Platinum Chip upgrades their entire arsenal and Armour. The Mk II displays a soldier for a face.

The upgrades to its arsenal include the following:


 * X-25 Gatling laser
 * M-235 rocket launcher
 * G-28 grenade launcher
