In the killing game featured in the Despair Arc of "Danganronpa 3: The End of Hope's Peak High School", there were 3 rules that set it apart from the other killing games shown in the franchise: all participants are put to sleep every 2 hours; during this time, a traitor would wake up and kill exactly one person; and all participants have a forbidden action, or NG Code, that will result in their death if they perform it.
This killing game (AKA The Final Killing Game) was in the Future Arc of the show.
