Horizon Worlds
Petricore partnered with Meta to develop original multiplayer worlds for Horizon Worlds, creating social experiences designed to bring players together through competition and cooperative play.
Our projects included Mob Quiz, a 32-player trivia game featuring hundreds of themed, player-driven, and gameplay-based questions that create a different experience every round, and Floodfill Dodgeball, a team-based twist on dodgeball where players convert opponents to their side until one team takes over the arena. Both worlds were designed to be easy to jump into, family friendly, and built around the social nature of Horizon Worlds.

Mob Quiz
Mob Quiz is a crowd focused trivia game scramble. With currently over 200 questions Mob Quiz is a mix of themed categories and our own always unique player and gameplay based questions.
“How many letters in total are in everyone’s names” is just an example of one of our many player and gameplay based questions.
Mob Quiz is a family friendly and social experience suited for all age groups and anyone who loves trivia or gameshows. With 32 player support, these questions will have answers of endless possibilities!
