The Whole Gang's Here

The Whole Gang's Here is a achievement and trophy in Fallout: New Vegas.

Requirements
It is awarded for successfully convincing all of the companions to join the Courier.

The eight companions one needs for this achievement are Arcade Gannon, Craig Boone, ED-E, Lily Bowen, Raul Tejada, Rex, Rose of Sharon Cassidy, and Veronica. One 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 eight companions; even hiring the same companion in eight playthroughs qualifies for this achievement.
