羽迹

When extreme disasters ravaged the Earth, its ecosystem was pushed to the brink of collapse — and birds vanished from the skies. To protect the last surviving birds, humanity built enormous biodomes.

Inside these vast biodomes, you'll embark on a birdwatching journey like no other, built around deck-building, Birdpedia collection, and long-term progression. Travel across diverse environments, encounter birds of all shapes and sizes, and study them through card-based gameplay — gradually filling the pages of your very own Birdpedia.

Map Exploration

Set out on expeditions across fixed maps, triggering events, discovering treasure chests, and encountering different birds and poses along the way. As your records grow, more areas and rarer birds will gradually open up to you.

Birdwatching Card Gameplay

Encountering a bird during an expedition triggers a card gameplay. Play cards to raise your Research, while managing Distance, Alertness, and your resource pacing — complete your research and recording before the bird flies away.

Long-Term Progression

As long as your Stamina holds out, everything you earn on an expedition comes back to base with you. Spend your haul on items, Talents, and card upgrades — or use the gear and cards you've gathered along the way to build and refine your birdwatching deck, strengthening your birdwatching abilities.

Birdpedia Collection

Complete a bird's research in card battles to collect the Birdpedia entry for its corresponding pose. As your Birdpedia grows, the secrets of the biodome will slowly unfold.
