One Turn Kill news & patch notes

Hello. The currently available demo version of ‘One Turn Kill’ is scheduled to be discontinued shortly. As time has passed since the demo's release and its specifications have become outdated compared to the full version, we have decided to temporarily end the demo's availability.

Ideally, we would update the demo to match the full game's specifications. However, we are currently focusing our development resources on updating the main game and adapting it for platforms like the Nintendo Switch. Therefore, updating the demo in the near future is difficult. The demo is scheduled to be taken down approximately one week from now (around the end of January 2026).

Plans for a new demo version are currently undecided. We sincerely appreciate your understanding regarding this matter and humbly request your continued support for the evolution and refinement of One Turn Kill. Thanks,

Team DenDen and Waku Waku Games.

Thanks everyone for playing One Turn Kill!!

We’ve implemented several bug fixes. We hope you continue to enjoy the game.

We’re currently investigating an issue where the game may fail to launch when a controller is connected.
