The good news is that S.T.A.L.K.E.R. 2 is back in development at GSC Game World, but the bad news is that it isn't going to be released until 2021. That's going to be a long wait.
The news was confirmed when a link to the official S.T.A.L.K.E.R. 2 Website appeared on the GSC Game World Facebook page. At the moment there's only a splash image with a date, so we don't have any information on the game other than that, but hopefully we hear more in the near future.
What would you like to see in S.T.A.L.K.E.R. 2?
