Post Apocalyptic Storm | Metro Exodus
Metro Exodus is a great damn game. The story, gameplay, combat, visuals. A masterpiece from 2019.
It's like a very linear, story based S.T.A.L.K.E.R
Not completely open world, but each map is pretty big either way.
But its very immersive, from the Geiger counter ticking to sitting on bed drinking water to faring the train with your comrades.
Its prequels are even better. Metro Last Light was basically a psychological horror because of the dark ones.
