Sensha-dou theatre secret/Girls und Panzer player models

For those who dont know Sensha-dou is the fictional martial art of tank battling from Girls und Panzer
Would be cool to have another secret room and another achievement to go with it! Maybe it could be designed like the School hangar used in the series or a similar sort of hangar style!
I think we need more secret rooms!!/[and more dance moves] lol
Would also be nice to have some Girls und Panzer player models running around
