The Whole Gang's Here

The Whole Gang's Here is a trophy/achievement in Fallout: New Vegas which is awarded for successfully convincing all of the companions to join you.

The eight companions you need for this achievement are: Arcade Gannon, Craig Boone, ED-E, Lily Bowen, Raul Tejada, Rex, Rose of Sharon Cassidy, and Veronica Santangelo. You must get all the companions in one game in order to get the achievement.

Bugs
This achievement may on occasion bug and instead of hiring all of the companions, all you need to do is hire 8 companions; even hiring the same companion in 8 playthroughs qualifies for this achievement.
