314 URB-LOC 0017 was one of several Advisors stored within the Citadel prior to its destruction.
Half-Life 2: Episode One
Alarm bells start ringing as 314 URB-LOC 0017 is loaded into its pod to be launched to safety from the self-destructing Citadel. As Alyx examines the foreign creature, the Advisor unleashes a painful telepathic attack on Gordon and Alyx, driving them from the room.
Half-Life 2: Episode Two
The crashed Advisor pod seen outside the barn complex is labeled 314 URB-LOC 0017. This suggests that the Barn Advisor may be the same individual, though it is equally likely the model was simply reused.
Like all Advisors, 314 URB-LOC 0017 has powerful telepathic and presumably telekinetic abilities. In response to Alyx's unwanted examination, it uses a telepathic attack that causes both Gordon and Alyx immense pain, as well as distorting their vision. The attack does not do any actual damage, but persists as long as Gordon and Alyx remain in the room.
Behind the scenes
- The shaft seen in the Citadel in Episode One where the Advisor leaves is one of the oldest concepts created for Half-Life 2. An early WC mappack map ("
proto_citadel_advisor.vmf") features a prototype version of it.
