GSC GameWorld has just released the first official screenshot for S.T.A.L.K.E.R. 2. S.T.A.L.K.E.R. 2 will be using Unreal Engine 4, and this screenshot will give you an idea of the graphics/visuals it will feature.
From what we know so far, the main inspiration for S.T.A.L.K.E.R. 2 is the original trilogy (Shadow of Chernobyl, Clear Sky and Call of Pripyat). STALKER 2 will be the most ambitious game from GSC GameWorld, and its main feature will be its unique atmosphere. The developers aim to make a really atmospheric game, similar to what the original STALKER was when it came out.
Furthermore, the team will be working on making modding tools so that modders can start creating new content when the game comes out.
