Welp. Stellar Blade's Twitter page has not had a single tweet since September. It's dead. FUCK.
I wouldn't worry about it too much. It's one of my most anticipated playstation games as well, but it's not over until it's over.

The game is still listed on the playstation store as a game you can add to your wishlist.
