Fallout: New Vegas Walkthrough -> Features
Traits, or additional features in Fallout: New Vegas, add subtle details to a character's personality. Each has both advantages and disadvantages. If you want to take advantage of the former, you have to accept the latter! A character can have up to two traits, or none at all.
