The DioField Chronicle has been available on PlayStation 5, Xbox Series, PlayStation 4, Xbox One, Switch and PC via Steam for a couple of months now. Since then, attention has now shifted to post-launch support of the game.
In fact, publisher Square Enix and developer Lancarse have announced a huge free update that will be coming to the game in March of 2023. The update will add a new scenario, weapon, skills, mode, and a difficulty level. You can see a trailer for the update down below.

Thank’s for posting this, i was planning on starting The DioField Chronicles after finishing some other games. Surprised it includes a new scenario, weapons, skills and a difficulty level in a free update. Sounds more like an expansion with the amount of content included.
