Speaking of S.T.A.L.K.E.R. 2, here are a few new pieces of concept art
The last one is interesting because it’s from a familiar location. Can anyone guess from where it is?
Also on their VK page there are a few pieces of artwork
The car park at the Cordon
Abandoned church in the Swamps
Pripyat / Jupiter underground
I have a hunch that the devs are hinting at a time and space anomaly. There was something similar in both Clear Sky and Call of Pripyat. 
Also I’m glad they are sticking close to what we were used in the first games when it comes to the design of the factions.
Duty and Freedom in SoC / CS / CoP
