The Battle Cats POP! pulled from the European 3DS eShop

In Europe, The Battle Cats POP! is no longer available for purchase. It’s simply been removed – and it’s unclear why at the moment. However, those who bought the game previously should still be able to re-download.

We should also stress that this news only applies to Europe. A quick look in North America indicates that nothing has changed with The Battle Cats POP!
