This RPG looks similar to Pokémon, but rather than taking part in turn-based battles your creatures (known as Beasties) take part in turn-based volleyball matches instead.
Each Beastie has a unique personality and teamwork style, which helps them build different types of relationships with other Beasties and learn various combo moves as a result.
The aim is to progress through the games story and win the Beastieball League.
