Snail Games USA unveils open‑world sandbox ‘9 Yin Sutra: Immortal’

Snail Games USA announced its upcoming open‑world sandbox training game “9 Yin Sutra: Immortal”. The single‑player title, which also supports online co‑op, lets players start as ordinary humans and pursue the path to becoming an immortal sage through cultivation, exploration and survival mechanics. Developed with Unreal Engine 5, the game features a massive 1,600 km² map—roughly 2.5 times the size of Tokyo’s 23 wards or 2.4 times Lake Biwa—and includes a flying‑sword mode, extensive building tools, rune‑crafting and cross‑platform progression. The initial release will focus on PC via Steam, with plans to expand to additional platforms later.
