Hello everyone,
at the moment the achievements are in development.
Don't be surprised to see them already on shop page but not yet in game.
They can't be added to Steam in an "hidden"- or "in development"-mode. Once created, they are visible. That is unfortunately the case with Steam.
But they will be available in-game with the next update. ːsteamhappyː
Have a nice weekend and see you soon
