Shawn Rivers is a British Rainbow operative. He was part of a two man advance team sent in by Rainbow at the start of the siege.
Shawn is the second half of Brian's team, every bit as capable as his leader. Responsible for supporting Brian's more direct actions, Shawn's expertise includes tagging enemies, sniping hostiles, rerouting electrical power and security systems and many other skills. An older and more experienced soldier, Shawn often acts as a calming influence on Brian's more impulsive tendencies.
Shawn gives his life in order to prevent the virus from being spread through the Las Vegas water supply.
