Eris Chaos was an Niz Chicoloco/Sinbad spin-off game that never got past the concept stage. Not much information about this cancelled game is known, but it was going to take place after the events of Niz Chicoloco vs. Eris; Eris the goddess of chaos and discord would have been planning to infiltrate every place and steal items therein. It was also going to have stealth elements in this game.
- It is unknown if the characters from Niz Chicoloco or Sinbad would appear in the game as either allies or foes.
- Some of the game's elements would have most likely been similar to the scene in Sinbad: Legend of the Seven Seas where Eris steals the Book of Peace.
- It is unclear whether if it is related to the failed Eris TV spin-off pitch Gingo made or not.
