Having iterated for two years without finding its audience, the project was cancelled, with servers to close a few months later on 27th April 2018. Poor player retention was cited as the leading cause.

  I haven't read the whole review yet (and this isn't really related to the actual game itself), so I'm not sure if this was mentioned, but considering how the developer is Epic Game studios and that Paragon shut down shortly after Fortnite blew up (and that classic "we definitely won't shut down the game" PR just weeks before they announced they were going to shut the game down...   Because the reality is that money talks, it was unfortunate, but not really a surprise that Paragon was shut down.
