According to the official Girls und Panzer website, several New Game!! characters will be making an appearance in the Girls & Panzer: Great Tankery Operation! smartphone game for iOS and Android mobile devices.
New Game!! and Girls und Panzer don’t really have much in common as the former is about the daily lives of game developers, while the latter is about girls fighting with frigging tanks.
But now, it seems that the employees of Eagle Jump will be trying their hand in tankery for a special New Game!! x Girls und Panzer collaboration.
The website does tease that players may be able to play a team which consists of Aoba, Hifumi, Hajime, and Yun, but they didn’t reveal anything official yet.
