Hello everyone,
We are pleased to announce that ASTLIBRA Gaiden: The Cave of Phantom Mist
will be launching on the Nintendo Switch eShop on October 17th. Unlike the
Steam version, the Nintendo Switch version of ASTLIBRA Gaiden will be a
standalone product. Players do not need to own ASTLIBRA Revision or start it
up to play Gaiden.
Thanks again for your continued support and patience!

然後跟Steam不一樣，會採獨立產品的方式發售而非DLC
