First announced by Perfect World Games (Wanmei) back in April 2021, One-Punch Man: World is one of two One-Punch Man mobile games being developed by major game companies in China right now (the other one here). Recently, other than droipping a new trailer consisting of in-game graphics, it was announced that the first beta test will being on 3 November. I highly doubt that Saitama will be a playable character though.
One-Punch Man: World is touted by Perfect World Games as the “first mobile action title” based on the One-Punch Man IP, with players being able to manually cast all the iconic skills found in the source material. Personally, I feel that this is an awesome change of view, as the other titles are turn-based. Players can also explore familiar locations in full 3D, take part in co-op PVE boss raids, and many more. Stay tuned for updates!
