Another S.T.A.L.K.E.R. sequel is underway at GSC Game World. Again.

GSC Game World CEO Sergiy Grygorovych announced today in a very brief Facebook post that his company is developing S.T.A.L.K.E.R. 2.

An official website is up, but there’s no info there aside from a 2021 release window.

In response to the news, Epic Games employee and SteamSpy creator Sergey Galyonkin tweeted "guesss the engine", which suggests S.T.A.L.K.E.R. 2 will use Epic’s Unreal Engine 4.

S.T.A.L.K.E.R. is uncompromising Ukrainian FPS survival horror series set under the shadow of the Chernobyl incident. It is seen as a precursor to the open world survival game craze, and comprises three entries: 2007’s S.T.A.L.K.E.R.: Shadow of Chernobyl, 2008 prequel S.T.A.L.K.E.R.: Clear Sky, and 2010’s S.T.A.L.K.E.R.: Call of Pripyat.

This isn’t the first time GSC Game World has announced S.T.A.L.K.E.R. 2; In 2010, the game was announced with a 2012 release window.

However, the following year, several sources reported turmoil at GSC Game World. It was rumoured that the studio would close (it did), that the game wouldn’t be released (it wasn't), and that Ukrainian government intervention may have been the culprit (who knows).

S.T.A.L.K.E.R. 2 was then cancelled, and GSC scattered to the radiation-poisoned winds.

In 2012, there was confusion over who owned the rights to the franchise, with Call of Pripyat publisher BitComposer Games claiming it had acquired the game’s licence after buying the rights to the novella on which the game is based – Roadside Picnic by Boris and Arkady Strugatsky.

GSC would reopen in 2015, and released real-time strategy title Cossacks 3 in 2016.
