Survivor Brother is a combined game of Survivor and Big Brother. One team wins, and the other goes through a very difficult process. They compete in another challenge and the winner is the Head of Team (HoT :P). They nominate 2 people and the rest vote!
When 5 are left the teams merge. The winner gets HoG (head of game) and noms two people again.
At the final 3, the jury (the people who got voted off) votes for the winner!
