First Announcement
On August 13th, 2010, GSC Game World announced that a full fledged sequel to S.T.A.L.K.E.R. : Shadow of Chernobyl was in the works and was slated to be released in 2012. Billed as "the next chapter" in the series by CEO Sergiy Grygorovych, the game was to use a new multi-platform engine built off of X-Ray, that the design team was building from the ground up. No other details were given at the time of the announcement.
On December 9th, 2011, the Ukrainian News Agency (then UkraNews) announced that GSC Game World would be closing down. Rumors claimed the closure was because of CEO/founder Grigorovich's unhappiness with the development progress of S.T.A.L.K.E.R. 2, a claim which was later refuted in a Twitter post by GSC, a post which would later be taken down. Beyond commenting on the rumor, the GSC Twitter also stated "We will do our best to continue. However, at this moment, nothing is certain." Soon after, a number of GSC employees formed Vostok Games and began developing Survarium.
Second Announcement
Following a revival in 2014, GSC Game World posted on May 15th, 2018 that development of S.T.A.L.K.E.R. 2 had been restarted, with a projected released date of 2021. This was further confirmed the following day on Sergei Grigorovich's Facebook page.
On July 23rd 2020, a first-look trailer for S.T.A.L.K.E.R. 2 was shown as part of the July Xbox Series X event, with the game slated to be a timed exclusive to Xbox Series X and PC, alongside being part of Game Pass at launch. New details were added to the official website, including news that development has shifted from a proprietary engine to Unreal Engine 5. During Microsoft's E3 2021 presentation, a second trailer was shown, showcasing characters, combat, and environments from the game. The trailer included a tentative release date of April 28, 2022, and a new subtitle, "Heart of Chernobyl". On January 12, 2022, the game was delayed to a new release date of December 8, 2022.
In March of the same year, the subtitle was changed to "Heart of Chornobyl", replacing the location's Russian spelling with the Ukrainian spelling, a move that was assumed to be related to the Russian invasion of Ukraine begun in February 2022. As a result of the invasion, part of GSC's development team was reportedly relocated from their Kyiv headquarters to Prague.
