Brown Anderson was a member of B.S.A.A unit. In 2009, he was deployed and participated in the events of Kijuju outbreak and sometime after that he retired and was hired as an instructor for the participants and to monitor Idol Survival, becoming specialist in survival techniques and tactics. After zombie infection spreading on the island, he teamed up with Laura Bierce after saving her life and they worked together killing zombies alongside Crazy Alexander. Eventually they swam to the safety of the White Castle cruiser. However, the cruiser was soon swarmed with zombies and they were forced to climb to the top of the boat where he ran out of bullets. Alex committed suicide to avoid being eaten alive. Brown, distracted by this, was then grabbed by the zombies, but managed to survive by jumping into the ocean and was saved by Laura. Brown later organized small camp along with other survivors.
