S.T.A.L.K.E.R. 2 is still years away so here's a banquet of irradiated exploration and scavenging to tide you over. Dead Air is a standalone mega-mod (no purchase necessary) for bleak FPS sandbox series S.T.A.L.K.E.R. Built on top of the fan-upgraded OpenXRay engine and using Call of Chernobyl's massive world map, it offers an uncompromising but accessible survival sandbox that looks good and runs better than any similarly huge S.T.A.L.K.E.R. mod out there.
