Per the official description relayed by Video Games Chronicle and PCGamesN, Cal Hampton is Jason Duval's friend and an associate of Brian Heder, occasionally helping him out on jobs.
He's described as the chilled sidekick who's always there for a good time, but loyal until the very end. A dedicated conspiracy theorist, he spends part of his free time being suspicious of flocks of birds flying in formation and listening to the Coast Guard frequency.
