Angrymals has been in development since 2015. It is being developed by Sionera Entertainment, a boutique Italian game studio, which was acquired by Catheon Gaming, a leading blockchain game publisher in January 2022. The team's focus now is to convert the existing Angrymals game into a blockchain, play-to-earn version. Catheon Gaming will support the project with its expertise in blockchain integration, marketing and community building, and fundraising and listing support.
