Mason was born in Flint, Michigan and grew up dirt-poor. His family was anything but kind. In a city filled with poverty and violence, Mason was eventually introduced to the crime life during high school. Mason saw this as his only way out of the hell hole that was Flint. He did dirty jobs for money, eventually making his way up the ranks of the ever-expanding crime syndicate until he was essentially the right hand of the man who led them. War broke out between them and another gang, leading to a need for heavier weaponry. Mason was to meet a shady weapons dealer in Chernarus. The deal went south, and Mason witnessed his best friends death right before his eyes. After that, Mason fled into the wilderness during the middle of a massive gunfight, knowing it was his only chance at survival. Mason had become lost in the woods for a week before he eventually found his way back to Zelenogorsk. However, he had returned to a society forever changed by the outbreak.
