PRAGUE, Nov 18 — Ukrainian studio GSC will on Wednesday release a long-awaited sequel to its hit S.T.A.L.K.E.R. video game, fine tuned during the Russian invasion which forced many of its staff to leave the country.

The post-Apocalyptic first-person shooter game is set in a fictional version of the exclusion zone around the Chernobyl nuclear power plant that was hit by a deadly accident in 1986.
