Otterly Lost, an open-world adventure game from Soulworks Interactive starring an otter named Otto, is set to launch on September 23, 2026, for PC. A demo with a dress-up feature is available on Steam, and development is in final polishing stages.
Soulworks Interactive's Otterly Lost follows Otto, an otter swept from his mountain home by a natural disaster, as he explores an island full of mystery. The open-world adventure spans water, underwater, forests, caves, and shipwrecks, where Otto completes quests for the island's unique animals, solves puzzles, and uncovers the cause of mysterious earthquakes to restore the balance of nature. Players collect shells and items to strengthen physical abilities and equipment, use tools like stones and light puzzles for exploration, and customize Otto's appearance with hats, clothes, and accessories.
The game is confirmed for a September 23, 2026 release on PC. A demo is available on the Steam store page, and the developer states development is in the final stages of polishing, testing, and story adjustments. The release time and time zone have not been announced, so the date may shift in Japan. The game does not support Japanese and is a single-player experience.
In June 2026, the demo received an update that added a dress-up feature and general gameplay improvements, signaling active development ahead of the planned launch. The developer's note that Otto's story has touched many people suggests early community interest, positioning the game as a notable indie release in the open-world adventure space.
