Director of the Eastern division, Hildern controls the Dam's power from Camp McCarran. If you are in front of the two vending machines you missed the OSI lab on the right that leads to the office of Hildern. He only cares for his research which also includes trying to prevent a shortage of food in the NCR. He is constantly outmatched by Keely (who he has a very low opinion of), and often takes credit for the work of his assistants (putting his actual competence for his position into question). He was trained by the Followers of the Apocalypse and left to help found the OSI. He believes in advancing himself through his research and eventually hopes to get to OSI Central.
Dr. Hildern can be found in his office located inside the Camp McCarran terminal building in the southeastern area on the ground floor of the terminal. Enter through the leftmost entrance of the terminal building.
xbox360 Hildern may exhibit a dialogue bug preventing him from any new dialogue choices once the quest There Stands the Grass has been completed. As a result, it is highly recommended that the player complete all other related quests to Hildern prior to completion of There Stands the Grass. This includes You Can Depend on Me which leads to the completion of Heartache by the Number affecting the player's ability to recruit Rose of Sharon Cassidy as a companion.[verification overdue]
