Hello Commanders,
CN, JP, KR Metal Waltz versions will soon be entering beta, details regarding the English version are below:
Happy Universe will be publishing the English version instead of What's Up Labs due to regional rights, however there are still some resources to prepare. Once ready, the English version will be released under the "Panzer Waltz" name.
Thank you for your interest and support, we hope to see you soon!
Happy Universe Team
