Berkley

Berkley is a resident of San Fierro who is a rival of Zero. The two each own their shop (Berkley RC and Zero RC, although their rivalry goes back to when Zero won the top prize at a science fair. The two are, in 1992, involved in a war involving remote control vehicles. Berkley, having just returned to San Fierro, launches 'a full scale attack' on Zero's shop and transmitters. Berkley's delivery men and vehicles are then targeted by Carl Johnson, and then defeated in a remote control army battle. After losing the battle, Berkley is told to pack up his business and leave San Fierro.

The whereabouts of Berkley are unknown, although he continues his rivalry with Zero. He is informed by Zero of the casino heist planned by Carl Johnson, Wu Zi Mu and the San Fierro Triads. He alerts the authorities, who turn up at the Verdant Meadows abandoned airfield, where the money is taken. Berkley is not mentioned after this event.
