VentureBeat reports that makers of the game, Ndemoc Creations, were in formed that the game “includes content that is illegal in China as determined by the Cyberspace Administration of China“. Oddly enough, Plague Inc is still available via its Steam page in China.

— Plague Inc. / Rebel Inc. (@NdemicCreations) February 27, 2020 As for what exactly about the game is illegal, it remains unknown to all but the Cyberspace Administration. Though VentureBeat speculates that it may be because the virus in the game always starts in China. The outlet also reports that Plague Inc. now has a “fake news” mode, in addition to the addition of anti-vaxxers from back in March last year. For now, Ndemic Creations is getting in touch with the Cyberspace Administration to find out what exactly it finds illegal in Plague Inc. Though the devs do provide a disclaimer that reads “as a tiny independent games studio in the UK, the odds are stacked against us”. For those who are not in China, Plague Inc. remains available on all platforms the game is already on. The other game by the devs, Rebel Inc., also remains available on all platforms in and outside of the country. (Source: Ndemic Creations via VentureBeat)
