I found an ad for a new Godzilla mobile game on the official webpage. Its apparently a puzzle rpg called Po colon Dungeons X Godzilla. It came out on October 23rd 2015. Heres a link to see for yourself (ps: hope you can read Japanese)
Well, me and LesStudios are working on pages for the Diamond Eye monsters. However, despite of this, neither of us have seen all of the episodes yet. So pretty much every article is currently a "stub".
