Ever since the Coronavirus epidemic went public, Plague Inc saw a significant rise in its player base. The game is centered around developing a 'perfect' plague that is meant to wipe out all life on earth. The Chinese market, in particular, saw a lot of takers for the game. Now, it appears that Chinese authorities have banned the game, citing that it is 'illegal content'. The game's developers —Ndemic Creations— announced its departure via a blog post.

We have some very sad news to share with our China based players. We've just been informed that Plague Inc. “includes content that is illegal in China as determined by the Cyberspace Administration of China” and has been removed from the China App Store. This situation is completely out of our control.
