Sephonie

Sephonie is a story-driven 3D platforming adventure about three biologists shipwrecked on an uninhabited island. You explore its vast cave network, study unfamiliar creatures and learn about the scientists’ memories, dreams and relationships as they face challenges underground.

The island and its researchers

In the near future, Amy Lim, Riyou Hayashi and Ing-wen Lin travel to Sephonie Island on a joint mission to research its creatures using state-of-the-art ONYX implants. A sudden storm shipwrecks them before they reach the island. Amy, a bold Taiwanese-American leader, comes from Bloomington in the midwestern USA; analytical Japanese-Taiwanese researcher Riyou lives in Tokyo; and kind, considerate Taiwanese scientist Ing-wen lives in Taipei.

As the trio explores, their motivations and loyalties are tested by physical obstacles and their own memories and dreams. Their growing closeness to one another and the island faces a threat from an ancient force brewing in its abyss, with consequences that may reach the world. The story explores the trio’s bonds, the priorities of nations and the connection between humans and nature.

Traverse the caverns

You sprint, jump, wallrun and use acrobatic moves to cross lush caverns, subterranean oceans, surreal cityscapes and rocky passages. The Teledash Vault flings you over high ledges, while wallruns carry you across dangerous outcroppings. You can grapple through the air with long-tongued Ribbats and climb cliffs using sticky-ridged Gripshrooms.

Linking with certain creatures grants new abilities that help you reach deeper parts of the island. The varied cave network is home to large and surprising creatures, as well as jade canopies and rusty sandstone spires.

Research creatures

You research the island’s unknown creatures by Linking with them. Each creature presents a challenge in the Puzzle Grid system: place colored tiles freely to form large islands of a single color.

Additional challenges

The main adventure takes 6–8 or more hours. After completing it, you can play the postgame Bubble Adventure and search for hidden items designed to challenge experienced spelunkers.
