About

Terra Fauna

Features
Read full description

Explore the world. Build your team. Terra Fauna turns real wildlife encounters into a living collection. Record a short video of an animal, enter the species you think you saw, and let on-device classification help verify your observation. Every successful encounter adds a unique animal to your collection. Its Health, Attack, Defense, Speed, and Dexterity are shaped by your level, the encounter, and the quality of your video. Discover new species for bonus XP, unlock field research, and collect berries that help your animals grow. Choose one of four teams—Earth, Air, Fire, or Water—and earn additional benefits from encounters that match your team. Revisit individual animals, explore their stats and moves, care for them, or release them in exchange for useful items. Features include: • A collection of 60 species • On-device animal classification • Unique stats and moves for every captured animal • Species information unlocked through field research • Earth, Air, Fire, and Water teams • XP, leveling, berries, and animal upgrades • Location verification for authentic encounters • Restrictions around zoos and other captive-animal facilities Terra Fauna is designed around respectful wildlife observation. Never approach, disturb, feed, or endanger an animal to complete an encounter. Your adventure begins wherever wildlife finds you.
