Big Brother 4

Big Brother 4, also known as BB4 Impel Down, is the fourth game of AP Forum's Big Brother. It was initially scheduled to be played in December 2015 with Kubihige as the host, which would have made it the first-ever winter Big Brother, but was postponed due to the mods being too busy. Kitsune Inferno then planned to host it in the summer of 2016, calling it Big Brother 4: The House of Shifting Walls, but after going inactive while hosting Survivor 6, he decided to withdraw. However, Kubihige took the mantle back up and hosted the game as Blackbeard, along with Wooden_Giraffe as Shiliew, NateRich as Victoria Cindry, and Nojiko as trappedolphin.

After 56 days, Jabra, played by second-time player Kitsune Inferno, was crowned the winner over Pappug, played by first-time player vorlianis, in a 5-2 vote.

Twists

 * Revenge Nomination: The first evicted player who chose Revenge over Redemption would be able to nominate a third HouseGuest for two cycles, giving these cycles three nominees; the third nominee would be able to participate in the Power of Veto Competition and be vetoed off the block. Brook, the first evicted HouseGuest, chose revenge, nominating Enel in Cycle 3. However, he failed to show up again to make a second nomination, and this twist is recognized by the mods as a failed one.
 * Redemption Challenge: Like Big Brother 2, evicted players could return to the game. They could initially decide between this or gaining the ability to revenge nominate, but after Brook chose Revenge, this became the sole option for evictees. The challenge involved a quiz followed by four challenges, as well as the evicted player having to post Escape the Void 5 times every cycle However, unlike in Big Brother 2 and in Survivors 4 through 6, someone coming back was not guaranteed, as a certain quiz score was needed to continue, and none of the HouseGuests who took the quiz passed, thus meaning no one came back in this game.
