Trivia

  • Madness is a state of frenzied or chaotic activity.
  • Defeating bosses in this map does not increase the counter of [Wrath Controller], [Diet Controller], [Detective] and [Madness Terminator] medals.
  • Host zombies make no appearance in this map, only origin zombies appear, except the Sting Finger (only host Sting Finger appears, no origin one).
  • This is the first extra chapter which Ganymede does not appear as the main boss of Round 2.
  • This is the first extra chapter that bosses don't appear in one arena together. Each boss arena is based on the one of each chapter in Zombie Scenario: Season 4 (except Round 1 and 2 are the same).
  • In Taiwan/Hong Kong and Indonesia regions, there are few glitches such as sound looping or the fact that it is almost impossible to hit Frozen Terror when he's going to perform the Snowball Slam.
  • There is a mistake of showing NPC message during the cutscene in round 2, which the texts show Gerard, but the image message shows Jim.
  • There is a bug in round 1 which Juggernaut does not give any damage, only the zombies do so.
