Twists

 * The Target Lists - Upon entering the house, each of the 18 housemates were given two other housemates that they are to target while playing the game. If a housemate is able to eliminate both of their targets, they would have an option of a secret advantage to help them in the game. However, each of the housemates believes that they're the only ones that have a set of targets and they're unaware that they're also being targeted by two other housemates.
 * Immunity Challenge - After being absent from Big Brother 17, the Immunity Challenge returns for its fifth overall appearance. Prior to nominations being made, the housemates, with the exception of the Head of Household, would face off in a competition. The winner of the competition would receive Immunity and could not be nominated for eviction. The Immunity Challenge was temporatilty halted during Week Five in order to make way for the Double Eviction week.
 * Double Eviction - Having not been present in Big Brother 17, the Double Eviction returned during the fifth week of the season. Throughout the week, two separate evictions would take place. By the middle of the week, one of the housemates would be evicted, and by the end of the week, another one of them would be evicted. During this week, the Immunity Challenge was temporarily suspended because of time constraints.
