The player controls different dinosaur species in direct confrontations, while exploring prehistoric settings, collecting fossils, and unlocking new creatures for their collection, in a formula aimed at a young audience fascinated by dinosaurs rather than at fighting-game enthusiasts.
It's part of the 'Battle of Giants' series (also known as 'Combat of Giants' depending on the market), which explored the same idea with insects and dinosaurs across several DS entries, always targeting the family segment of the European catalog.
