Onibi, a newly formed studio of games industry veterans who have worked on games like Baldur’s Gate III, Fall Guys, Fortnite, League of Legends, and World of Warcraft, has announced Tomo: Endless Blue, an anime-style open-world action RPG set in a boundless ocean realm inhabited by mysterious creatures. It will launch for PC via Steam in late 2026.
“We can’t wait for players to embark on the journey that is Tomo: Endless Blue,” said Onibi CEO Benjamin Devienne in a press release. “Each island in the Endless Blue is a self-contained world, shaped by unique traditions, Tomo, and beliefs. As players explore these islands, we hope they’ll enjoy being challenged by how these civilizations view the same world through vastly di erent lenses.”
Here is an overview of the game, via Onibi:
About
Set sail through the Endless Blue, an ocean realm inhabited by the Tomo. Team up with your companions to fight or enjoy daily life. Build vehicles and contraptions to explore procedurally generated islands and villages, and meet unique characters along the way.
When worlds end, fragments of their civilizations become islands adrift in the Endless Blue. As players embark on a journey to uncover the story of each procedurally generated island, they discover vibrant villages filled with characters and Tomo living their lives, every island and village a microcosm of a unique civilization.
Whether players want to battle alongside Tomo companions, build intricate vehicles and contraptions out of blocks, or live a cozy life with their friends, the world of the Endless Blue is theirs to discover.
Key Features
- Befriend the Tomo – Players will meet extraordinary creatures known as the “Tomo,” each with unique powers they’ll use while fighting alongside the player. Tomo are also the player’s day-to-day companions, helping them build, farm, craft, cook, and more.
- Procedurally Generated Worlds – The game utilizes a combination of handcrafted content and bespoke procedural generation to create vibrant and diverse islands. Each island offers a variety of challenges, including battles against Tomo Champions, searches for mythical Tomo, and the uncovering of hidden secrets in ancient ruins.
- Voxel Physics – Blocks in Tomo: Endless Blue adhere to real-world physics, allowing players to construct vehicles and contraptions to aid their exploration or daily life. Whether it’s a boat, crane, or airship, players can build their own machines block by block—the possibilities are endless.
- Terrain-Based Live Combat – Players can switch between their own point-of-view and their Tomo companion’s. The blocks forming the surrounding terrain can be used strategically to gain the upper hand: for example, spread water to cool down a fire Tomo, then hit the water with an electric attack for massive damage.
- Multiplayer Capabilities – The game supports offline single-player gameplay, local network multiplayer and distant server play. There’s no limit on the number of players—it’s as many as the player’s device or server can support.
