Metro protectron

Ticket Bots are Protectrons usualy found in metro stations that will ask for a Metro Ticket from the player. If you do not happen to have a ticket on your person, the Protection will attack you. After checking your ticket, the Protectron will remain friendly to you, and will walk around the metro station attacking any enemies such as Raiders, Feral Ghouls, etc. It should also be noted that there are similar Protecrons in Super Duper Mart and in the Old Olney sewers that ask for employee ID. The Old Olney Protectron will not, despite its repeated warnings, attack the player.

If a Ticket Bot encounters supermutants, it will repeatedly ask for tickets, causing the supermutants to laugh and mock it (until the Ticket Bot shoots them for "improper metro usage").
