Zanki Zero features additional content for players who have save data for games from the Danganronpa series on the same console as their Zanki Zero save data.
If the player has save data for Danganronpa 1.2 Reload, Danganronpa Another Episode: Ultra Despair Girls or Danganronpa V3: Killing Harmony on their PS Vita or PS4, Monokuma monsters will appear at random on Trash Island. Having save data for more than one of the games increases the probability of Monokuma appearing. Additionally, Danganronpa posters can be found throughout the game that increase the probability further. Defeating Monokumas grants a high amount of EXP and score, as well as powerful weapon and armor item drops.
